I also got one from Armslist. Pick it up at my FFL tomorrow. $781 shipped plus $25 transfer.

Presume used at that price, but that's a steal, assuming decent condition.
I had one stutter with mine with a hollow point, but generally just run ball. With 10.5" muzzle velocity, it should do fine if ever called on for defense.

I've got an AR6450 and an AR6951 and both are a lot of fun to shoot. Compare the C-Products and Metalform mags... the Metalform is really heavy duty and mine have performed flawlessly.

Here's a write up on the Colt Submachine Gun, 9mm NATO, if anybody's interested. This is the predecessor of the 6951https://www.smallarmsreview.com/disp...darticles=3431

Chuck Taylor's assessment (he carried one):

.223Pound is right. I've examined the ASC mags and they look OK, but I went ahead and paid a few bucks more for Metalform 32s. They are the same as Colt OEM. I didn't get any 20s as I didn't see the need.

I have a few Colt 9mm’s 6991(10.5 inch barrel) in similar and full auto and an DOE RO633 7.5 inch barrel in simi. All 3 are amazing. ASC and Metalform mags work well with FMJ, Flat Points and JHP’s of all weights.

I have to echo many of the observations above. I have both a 6450 (from 1995) and a 6951 I picked up a few years ago. Both love the Winchester 124g NATO. The round is among the dirtiest I've encountered, but in these blowback rifles it doesn't matter: I usually clean them after every range session or at least once a month. I use the synthetic safe Gun Scrubber but am interested in hearing more about non-chlorinated brake cleaner at a fraction of the cost. Are these products the same chemically?

The 6450 has a pretty high round count so I don't shoot it that often any more, but it's still accurate and all parts still original. My 6951 had a defective bolt catch, a simple fix, but I made the mistake of trying to go through the warranty to have Colt fix it. After they had the gun for two months, I asked that it be sent back and replaced it myself in two minutes. After that I put a Magpul fore end on it to aid in a more muzzle forward support hand grip for competition (I used to use it for Steel Challenge). Right now my primary PCC is a CZ Scorpion but I bring the 6951 along just in case I need the backup gun, or someone else does.

Fine rifles. Recoil is there from the heavy bolt, but that's the nature of blowback mechanisms.

Hello from Maryland, by the way...

Boss', I'm a Scorp fan as well; no where near as elegant as the Colt, but it works, and becomes amazingly compact with the folding buttstock.
The AR bolstop (and trigger guard) can be treacherous to replace, so I'm glad you got it changed without drama.
I've gone to a Geissele trigger in mine.
BTW, any idea what the standard buffer weighs, and have you considered replacing it with a heavier one?

I have not weighed my particular buffer but I'm cleaning the gun tomorrow and will get it on my scale. As for replacing it, other than 147g hollowpoints, everything has cycled through it flawlessly. I do have a Kak buffer that can be increased or decreased in weight, but that's for a 9mm AR build I can't seem to get motivated to build yet.

It's just a great gun. The CZ is too, and I just run it because it's a lot of fun. At non sanctioned events I run the Scorpion pistol with a brace as it's slightly easier to bring around and get on target...

Can't get close enough to see the takedown; what do you have?
My Scorp has the 8" bbl; it was originally a pistol, and this was before braces were kosher, so I tax stamped it.
Ever consider SBR'ing any of those? Neat collection!
