[ARCHIVED THREAD] - "Upgraded" my Colt 9mm SMG

Posted: 8/31/2015 9:18:35 PM EDT

Started out as a standard, select-fire Colt 9mm SMG. Upgrades performed:

TROS USA 3-lug 9" barrel

BCM KMR7

RRA 9mm flattop upper receiver

Magpul BUIS

Magpul MOE stock

Ergo pistol grip

Streamlight M3 light

BCM handstop

NiB coated the original bolt

Aimpoint CompM4 for now, because I had it lying around with nothing under it. I'll be ordering an Aimpoint Micro T1 soon to replace it.

I'll test fire later this week.

Very nice! I'd like to shoot that someday.

I've kept a stack of UZI mags just in case I ever get something like that... or an UZI.

Either one would be a nice addition!

Much bad-ass-ness there CMshoot. Any plans to suppress?

Is the hand stop backwards or do you like to run it like that?

Any chance you are going to sell the old upper & stock?

I really like the old stuff.

That is way too bulky ass of an optic for that carbine.

IMHO, I'd scrap the CompM4 and go Micro T1 unless you want something heavy you can throw at your target when the Colt mags jam the #$@% up like they always do.

I'd rock it.

I run the handstop backwards to keep from running my hand too far forward and shooting my fingers off. On my M4 I run my hand further forward than I can reach on this SMG.

Sorry, keeping the old takeoff stuff!

Like I said in my original post, I'll be replacing the CompM4 with a Micro T1 or similar. I know.....we look at the pretty pictures but we don't read the squiggly words!

Actually talked to a guy at Aimpoint earlier. I already own 2 of the T1's, might buy a T2 this time.

Years ago I ran this same SMG at a week long SMG Instructor workshop. Not a single stoppage or malfunction with the Colt or C Products mags. I intentionally didn't clean her all week, but no worries. On Friday I was doing 32rd bursts with no issues. The only issues I had originally had with this SMG were related to the ejector. With the assistance of 00bullitt, that problem was solved and she runs like a Swiss watch.

Talked to the SMG Instructors at GPSTC during my SMG Instructor certification. They said they have less stoppages, malfunctions and parts breakages with the Colt than with the HK MP5.

I thought I was the only one who runs them backwards, especially on my SBR's. Same reason as Shep. Looks good, I want a .45 though.

.45 would be cool. I've got a M1A1 Thompson and an M3A1 I can play with whenever I want, although they ain't mine.

trust me, it ain't the mags when you have issues with a 9mm jamming.......I have an out of spec lower with a magwell adapter I had to hammer in running with promag mags someone threw away because they said they wouldn't run......the issue is that the there is a design flaw in the way the barrels are made........that originated with the first ones colt made and everyone else just copied.....

Correction....

....will be cool......we'll finally have the first production mags in hand in the AM....have to make a magwell adapter, barrels and bolts are already in production.....Blowback 45 with an adapter and mag to fit a standard lower should be on the shelf by November ........so far we have 5 inch and 16 inch barrels being run on the Mori Seiki.....hope to be running 8.3 inch next week.....long enough to get the muzzle threads in front of a 7 inch hand guard.

and I love what ya done with the Colt...........

Not all of them do it....

..........but all the tuning with getting the mag adapter at the right height......is eliminated with the way I cut feed ramps.....done a bunch in the pistol caliber forum for people who were having issues......corrected the feed cone and they run perfect.......

And I like the sight......I run an Aimpoint Comp M2 on all my stuff.....My AR45 that rides around with me...........
