00:00:08:01 00:00:10:15
– [Announcer] Hey everybody
Adam from Atlas Gunworks.

00:00:10:15 00:00:13:21
Alright first video in
the Mag Tuning Series.

00:00:13:21 00:00:17:02
I’ve got a pile of SV Mags
here and we gotta make sure

00:00:17:02 00:00:18:15
they drop free from the gun.

00:00:18:15 00:00:20:18
That’s the very first thing
I do because that gets

00:00:20:18 00:00:22:12
a little violent.

00:00:22:12 00:00:24:24
This one’s a little sticky
but for the most part

00:00:24:24 00:00:26:07
it drops free.

00:00:26:07 00:00:28:03
Now keep this in mind.

00:00:29:05 00:00:32:24
The EVO grip versus so
the PT EVO grip versus

00:00:34:14 00:00:38:01
the plastic grip versus the SV grip versus

00:00:40:07 00:00:43:04
whatever else, there’s a regular
PT grip there’s other grips

00:00:43:04 00:00:44:09
out there CK.

00:00:44:09 00:00:46:19
They’re all a little bit
different angle in here and that’s

00:00:46:19 00:00:49:08
gonna matter on the tubes
there’s not a lot of clearance

00:00:49:08 00:00:52:14
there so different ones
might need some adjustment.

00:00:52:14 00:00:55:12
But the systems kinda all
the same on how you do it.

00:00:55:12 00:01:00:08
Keep in mind that if you
have old STI guns or STI guns

00:01:00:08 00:01:04:03
the SV tubes often don’t fit
in here without a frame cut so

00:01:04:03 00:01:07:01
this is more for the premium guns,

00:01:07:01 00:01:08:09
our guns,

00:01:08:09 00:01:10:25
I dunno who else is doing
those cuts the relief cut

00:01:10:25 00:01:15:04
in the frames but all our
guns will take a SV tube.

00:01:16:17 00:01:19:21
this system we have another
video out that predates this

00:01:19:21 00:01:22:09
that talks about the mag
tubes but this system also

00:01:22:09 00:01:25:17
works for the old style for the STI tubes.

00:01:25:17 00:01:29:06
So SV old style, SVI and the
tuning on those is almost

00:01:29:06 00:01:33:10
identical so anyway this one’s
not so bad we’ll be okay here

00:01:33:10 00:01:36:15
we’ll find some that don’t cut.

00:01:36:15 00:01:38:07
So this one’s tight.

00:01:39:13 00:01:43:13
Drops free but it goes
in tight that’s one kind.

00:01:47:10 00:01:48:24
That one’s not bad.

00:01:50:13 00:01:52:03
This one’s not bad.

00:01:55:06 00:01:57:08
This one won’t drop free.

00:01:57:08 00:02:00:11
Now sometimes they won’t
even come up into the

00:02:00:11 00:02:04:03
into the mag wall
three-quarters of the way.

00:02:04:03 00:02:06:11
So what do we do now?

00:02:06:11 00:02:09:06
Well we’re gonna start to
figure out where it doesn’t go.

00:02:09:06 00:02:11:23
And the beauty of this is
that the metal will have

00:02:11:23 00:02:14:07
witness marks here so I see

00:02:14:07 00:02:17:16
and I used to do this in a
vice and now I do a lot more

00:02:17:16 00:02:21:01
with just a hammer with
the nylon tip side.

00:02:21:01 00:02:25:00
So I’ve gotta witness mark
here and a witness mark here.

00:02:25:00 00:02:26:15
A little investigation.

00:02:26:15 00:02:28:24
Now I know where to look
but it’s gonna be a lot in

00:02:28:24 00:02:31:03
this front section from here to here.

00:02:31:03 00:02:33:08
So I’m just gonna hit this.

00:02:33:08 00:02:34:15
(hammering onto metal)

00:02:34:15 00:02:37:20
A few spots let’s see what happens.

00:02:37:20 00:02:40:05
I think it’s a little better.

00:02:41:10 00:02:45:01
Now I’m getting a witness mark here.

00:02:45:01 00:02:48:04
So I almost always start
with this front side because

00:02:48:04 00:02:50:10
that’s almost always where the issue is.

00:02:50:10 00:02:51:14
We’re close.

00:02:51:14 00:02:56:09
Now oftentimes too you’ll see
that this top part’s too wide

00:02:56:09 00:02:58:16
and as you come up into the frame

00:02:58:16 00:03:00:24
there’s a hiccup as it kinda

00:03:04:11 00:03:06:04
so what you’re doing is just
kinda looking to see where

00:03:06:04 00:03:07:13
stuff rubs now,

00:03:07:13 00:03:10:13
if you’re afraid to do this,

00:03:10:13 00:03:12:11
the safe method,

00:03:12:11 00:03:15:21
and again I do it so
much that I don’t I don’t

00:03:15:21 00:03:18:09
have to do this very often
but this is the safe method.

00:03:18:09 00:03:20:03
On your workbench you should
always have one of these

00:03:20:03 00:03:24:01
fat Sharpies and blue’s
the best color I think.

00:03:30:14 00:03:33:18
So let’s just get the front worked out.

00:03:33:18 00:03:36:22
There’s gonna be potentially
some tuning over here

00:03:36:22 00:03:38:24
actually while we’re here

00:03:39:20 00:03:43:17
I think that that’s probably
rubbing’ right there a lil bit.

00:03:43:17 00:03:46:19
The SV tubes which in
the fall of ’17 still our

00:03:46:19 00:03:50:03
favorite tube always they
must clamp ’em right here.

00:03:50:03 00:03:53:23
They have a little deal right
here and you’re gonna need

00:03:53:23 00:03:54:19
to de-burn ’em with a
wheel or with a Dremel.

00:03:54:19 00:03:58:11
But I do like to get
’em to drop free before

00:04:00:10 00:04:01:21
I take that step.

00:04:06:01 00:04:06:22
Alright.

00:04:10:18 00:04:14:17
Just run it in and out a couple times.

00:04:14:17 00:04:16:06
See what we’re seeing.

00:04:16:06 00:04:18:22
Alright so here’s some drag marks.

00:04:18:22 00:04:21:02
That top one you don’t wanna
flatten that out too much

00:04:21:02 00:04:23:12
because it’s some of
that’s the way it comes in

00:04:23:12 00:04:24:23
the angles.

00:04:24:23 00:04:27:25
(hammering on metal)

00:04:30:24 00:04:32:01
There you go.

00:04:34:11 00:04:36:07
I don’t love this one.

00:04:37:25 00:04:40:22
Looks like we’re right here.

00:04:40:22 00:04:43:20
Just a little bit of contact maybe.

00:04:47:13 00:04:49:24
Now I want that to come up
and fall down on its own

00:04:49:24 00:04:51:16
so what’s happening is
it’s sticking when it’s

00:04:51:16 00:04:53:00
all the way up.

00:04:53:00 00:04:55:21
(hammering on metal)

00:04:55:21 00:04:57:20
You don’t have to hit
that tremendously hard.

00:04:57:20 00:05:00:23
We don’t want that to be wavy for sure,

00:05:00:23 00:05:04:08
just a little bit of stick
now sometimes this is over

00:05:04:08 00:05:07:12
(hammering on metal drowns out speech)

00:05:07:12 00:05:09:01
work this one side.

00:05:11:13 00:05:14:13
Alright so we’re not getting
progress there so let’s go back

00:05:14:13 00:05:16:13
with the marker there and let’s see if

00:05:16:13 00:05:18:17
it’s this front side.

00:05:18:17 00:05:22:18
I’m gonna show you a little trick here.

00:05:22:18 00:05:24:09
None of this is rocket
science and if you do it

00:05:24:09 00:05:26:09
a bunch of times and you

00:05:27:15 00:05:30:00
just get comfortable with it.

00:05:30:23 00:05:33:03
So I’ve got the mag in
the gun I know it doesn’t

00:05:33:03 00:05:35:09
quite drop free the way I want.

00:05:35:09 00:05:38:04
So wiggle it front to
back and left to right.

00:05:38:04 00:05:40:21
There’s a left or right movement
no front to back movement

00:05:40:21 00:05:42:13
so that would almost

00:05:43:09 00:05:45:23
always tell you that it
needs some front to back

00:05:45:23 00:05:48:05
adjustment so take it out.

00:05:48:05 00:05:49:23
And that what that’s
doing there is telling me

00:05:49:23 00:05:52:08
to start keep looking in
the front and stop messing

00:05:52:08 00:05:53:11
with the sides.

00:05:53:11 00:05:55:15
Now remember as you hit
the sides or the front

00:05:55:15 00:05:58:03
you’re moving it the other
direction so if I bang

00:05:58:03 00:06:00:11
on the side here I’m
gonna bow the front up but

00:06:00:11 00:06:03:06
see we’re pretty violent right there.

00:06:03:06 00:06:06:08
(hammering on metal)

00:06:22:01 00:06:24:15
So you’ve got just one
little bump in that system

00:06:24:15 00:06:26:17
where you come in and you feel it

00:06:26:17 00:06:30:02
you feel it drag right
here and I’m wiggling it

00:06:30:02 00:06:34:04
and it’s probably not front to back issue.

00:06:34:04 00:06:35:13
Let me click it.

00:06:36:10 00:06:37:06
No, it is.

00:06:38:24 00:06:41:20
So even though we’re dragging right here

00:06:41:20 00:06:45:12
it’s only it fits nicely when we get here

00:06:45:12 00:06:50:02
so we know is probably
the lower side of this so.

00:06:50:02 00:06:51:12
We’re gonna.

00:06:51:12 00:06:54:02
You’re always gonna have
some drag marks there.

00:06:54:02 00:06:55:01
There you go.

00:06:55:01 00:06:57:20
So we’re getting closer.

00:06:57:20 00:07:00:25
And you know again you’re
gonna have some drag marks.

00:07:00:25 00:07:03:10
(hammering on metal)

00:07:03:10 00:07:06:09
Now if you went this far
and it’s having problems

00:07:06:09 00:07:08:23
then we know it’s
definitely up in the top.

00:07:08:23 00:07:11:04
(clicks)

00:07:11:04 00:07:12:04
There we go.

00:07:13:02 00:07:14:13
Mag goes in mag comes out.

00:07:14:13 00:07:16:06
Mag goes in mag comes out.

00:07:16:06 00:07:18:03
That’s how we need ’em to fall that well.

00:07:18:03 00:07:19:23
Now remember as this hits
the ground or whatever

00:07:19:23 00:07:22:13
you’re gonna have to
re-tune them a bunch but,

00:07:22:13 00:07:25:17
that’s that’s pretty much how they go.

00:07:25:17 00:07:28:13
We’ll try a couple more,

00:07:28:13 00:07:31:05
see if we can’t find
one that’s really bad.

00:07:31:05 00:07:33:11
(clicking)

00:07:41:01 00:07:42:20
Now this one’s pretty hard.

00:07:42:20 00:07:46:19
So on this one let’s
just skip the step here

00:07:46:19 00:07:48:24
let’s assume it’s down at
the bottom of the other one.

00:07:48:24 00:07:51:11
Now if you get a set and they
were made at the same time

00:07:51:11 00:07:53:07
and you find them
together the problems are

00:07:53:07 00:07:55:14
probably in the same spots.

00:07:57:21 00:07:59:23
Most likely not always.

00:07:59:23 00:08:02:16
Hmmm that made it worse.

00:08:02:16 00:08:04:00
Alright so now we’re in here

00:08:04:00 00:08:06:22
I have some front to back and
I don’t like my left to right.

00:08:06:22 00:08:10:08
So that this is probably bound up up top.

00:08:11:09 00:08:14:09
And again I kinda know
where to do it but if you

00:08:14:09 00:08:16:23
witness these you know you
can take the marker and

00:08:16:23 00:08:18:16
do the whole thing really but you’ll see

00:08:18:16 00:08:19:22
where they’re dragging.

00:08:19:22 00:08:21:21
We don’t want crazy drag marks you know

00:08:21:21 00:08:23:24
where it looks like
it’s really peeling the,

00:08:23:24 00:08:26:16
you know there’s when it rubs
it’s gonna be nice and smooth

00:08:26:16 00:08:28:02
and you want it consistent thing there

00:08:28:02 00:08:30:16
but you’ll see where the

00:08:30:16 00:08:32:02
(hammering on metal)

00:08:32:02 00:08:33:06
bad spots are.

00:08:34:16 00:08:36:20
So still just a little bit

00:08:37:16 00:08:42:00
I don’t like the front to
back here but there’s some so.

00:08:42:00 00:08:44:22
(hammering on metal)

00:08:44:22 00:08:47:17
Just now we’re trying to
eliminate that as the problem.

00:08:47:17 00:08:51:21
And I think see now it’s got
plenty wiggle room in the back.

00:08:52:22 00:08:55:18
(hammering on metal)

00:08:55:18 00:08:59:01
So pretty sure this (clicking
drowns out speech) up top.

00:08:59:01 00:09:01:05
And you can come up here

00:09:01:05 00:09:02:03
at the top.

00:09:03:11 00:09:05:05
And just see.

00:09:05:05 00:09:07:21
So when I push this up here
you’ll feel a little resistance

00:09:07:21 00:09:09:10
when it goes over the mag catch

00:09:09:10 00:09:12:08
hold the mag catch open and
that resistance goes away right.

00:09:12:08 00:09:14:18
But we just push it up here and just like,

00:09:14:18 00:09:16:16
what is it dragging on?

00:09:18:23 00:09:20:17
What’s it dragging on?

00:09:20:17 00:09:23:12
This one drags really
heavy on the mag catch.

00:09:23:12 00:09:25:14
Oh here you go.

00:09:25:14 00:09:26:16
You can see it.

00:09:26:16 00:09:27:21
Right?

00:09:27:21 00:09:30:03
So this side’s this is a little

00:09:30:03 00:09:33:18
tube’s a little skewed this way so.

00:09:33:18 00:09:36:15
(hammering on metal)

00:09:36:15 00:09:38:07
We’re just gonna give it a little relief

00:09:38:07 00:09:41:03
it doesn’t take much and you’ll

00:09:41:03 00:09:44:01
see that look a lot better.

00:09:44:01 00:09:46:17
So does this mag work, yeah.

00:09:46:17 00:09:49:15
See it’s just a little bit clunky?

00:09:49:15 00:09:50:17
That clunkiness.

00:09:50:17 00:09:53:05
I don’t like it so we’re
just gonna keep workin’ it.

00:09:53:05 00:09:56:20
(hammering on metal)

00:09:56:20 00:09:59:12
Now why is that dragging well as we,

00:09:59:12 00:10:01:16
the front might’ve been
a little flat so as we

00:10:01:16 00:10:03:21
work this front out it
bows out now you can’t

00:10:03:21 00:10:05:23
really control which
side it’s gonna bow to

00:10:05:23 00:10:08:08
it’s gonna go one way or
the other so you gotta just

00:10:08:08 00:10:11:00
watch these kinda sides.

00:10:11:00 00:10:11:23
Alright so.

00:10:14:00 00:10:18:02
This tube is really good
drags just a little bit.

00:10:21:03 00:10:23:14
We’re right at that tail end.

00:10:24:11 00:10:25:22
Now it’s perfect.

00:10:27:17 00:10:30:15
So take your time use the
marker until you kinda

00:10:30:15 00:10:32:07
get the system down.

00:10:33:03 00:10:35:05
And then you can always
do it you can do it

00:10:35:05 00:10:37:21
with the slide off too so you
can see a little bit more.

00:10:37:21 00:10:39:22
You know this one

00:10:39:22 00:10:41:16
clicks in there super nice.

00:10:41:16 00:10:43:10
(clicks)

00:10:43:10 00:10:45:08
That was rough but,

00:10:45:08 00:10:47:15
so again now it’s fighting
me and you put ’em in

00:10:47:15 00:10:51:15
a bunch of times kinda
like I’m doing there’s

00:10:51:15 00:10:54:16
you know there’s things change
a little bit as you’re doing

00:10:54:16 00:10:56:23
this so you really wanna go

00:10:57:23 00:11:00:25
(hammering on metal)

00:11:03:19 00:11:05:23
Told you there was some relief there.

00:11:05:23 00:11:08:16
There you go, that’s what you really want.

00:11:08:16 00:11:11:07
Does it slide up and slide down.

00:11:13:18 00:11:14:22
So.

00:11:14:22 00:11:17:16
Now I’m gonna go back
and see that this one’s

00:11:17:16 00:11:19:20
dragging just a little bit

00:11:21:12 00:11:23:25
make an adjustment there now,

00:11:23:25 00:11:25:14
if things are crazy

00:11:26:11 00:11:29:22
if you’re seeing it be an
insane you know drag mark

00:11:29:22 00:11:34:06
every time maybe the mag
catch needs to be a little

00:11:34:06 00:11:36:14
10 seconds pull this out and

00:11:38:10 00:11:41:04
yeah I got a little bit of a burr on

00:11:41:04 00:11:43:11
that mag catch now unfortunately this is

00:11:43:11 00:11:45:16
the gun I’m shooting this
one of our site-blocked

00:11:45:16 00:11:49:14
prototype guns which is super cool but um,

00:11:49:14 00:11:53:12
my gun gets all the mags tested in it.

00:11:53:12 00:11:57:16
This one has a more so let’s
say you buy a PT EVO grip right

00:11:58:21 00:12:01:02
they’re not all the same internally.

00:12:01:02 00:12:03:05
These mags drop for this
gun you could have one

00:12:03:05 00:12:04:21
that’s tighter or one that’s looser.

00:12:04:21 00:12:06:24
This gun tends to run on
the tight side of those

00:12:06:24 00:12:10:05
internal dimensions so
that’s why we use this one

00:12:10:05 00:12:12:19
I always try to run a grip
a gun with a tighter grip

00:12:12:19 00:12:16:19
than everybody else’s just
so that when we test the mags

00:12:16:19 00:12:19:18
if they work in mine they
should work in everybody else’s.

00:12:19:18 00:12:22:02
So I’ll clean that up a little
bit and then that’ll stop

00:12:22:02 00:12:26:16
dragging on there and you’ll
see how much cleaner it is.

00:12:26:16 00:12:30:02
So hang on one second and I will do that.

00:12:36:02 00:12:38:09
(grinding)

00:12:47:13 00:12:50:18
Alright I’m back so that’s all
rounded out now real quick.

00:12:50:18 00:12:51:22
Just did it on a wheel.

00:12:51:22 00:12:55:23
Now one thing to keep in mind
with all gun tuning stuff is

00:12:55:23 00:13:00:02
we have metal on metal contact
a lot in these firearms.

00:13:01:01 00:13:04:02
That smoothed that out a little bit.

00:13:04:02 00:13:05:23
Smoothed that one out.

00:13:08:23 00:13:11:07
This one drags just a little bit.

00:13:11:07 00:13:12:24
Oh we haven’t tuned that one yet.

00:13:12:24 00:13:15:09
So we’ll wanna tune that one next.

00:13:15:09 00:13:17:25
So metal on metal contact
sometimes things don’t go

00:13:17:25 00:13:20:03
just as we planned and
you’ll start to see burrs

00:13:20:03 00:13:21:15
you know sharp edges.

00:13:21:15 00:13:24:05
You never want a sharp edge
so whether you’re using a file

00:13:24:05 00:13:26:25
or a little quick sandpaper or

00:13:26:25 00:13:30:03
caution you to use Dremels
but something like that

00:13:30:03 00:13:33:14
then you know get rid of those sharp burrs

00:13:33:14 00:13:35:17
so anytime you see something
sharp it’s gonna cut

00:13:35:17 00:13:37:25
the other metal putting
grooves in metal makes things

00:13:37:25 00:13:40:06
not smooth not consistent

00:13:40:06 00:13:43:16
same thing with this whole
system so for example

00:13:43:16 00:13:46:11
we’ve got a little bit of
a sharp edge right here

00:13:46:11 00:13:48:20
I’ll put this on a wheel and
take that off I don’t want

00:13:48:20 00:13:51:19
that groove’s just gonna
become worse and more of a drag

00:13:51:19 00:13:54:06
everything we want to be smooth and slick.

00:13:54:06 00:13:58:02
We want everything to just
work as flawlessly as they can.

00:13:58:02 00:14:00:23
So this is the first part of the video and

00:14:00:23 00:14:04:02
or the first video I guess
in the part one of the series

00:14:04:02 00:14:08:06
and we’ll do parts two through
five comin’ up here soon.

00:14:09:02 00:14:11:16
We’ll see you on the range soon.

00:14:11:16 00:14:14:08
