Never tried but I "think" the idea of a blowback action is the bullet is gone before the bolt moves. So it seems that the bolt would go no matter how much less barrel there was. As long as these have been around there is surely some who have made an NFA weapon out of one. Somewhere out there is probably some reviews and such on how they did it.
I did a quick search of someone who had made or tried to make an NFA out of one of these and nothing seems to be popping up. Kind of surprised me. So don't know if some have tried and ran into some kind of problem or what.
That's a good one - and I found another, possibly even closer to the action of the Mech Tech - this one shows a Tec 9, which seems to have a very similar setup to the Mech Tech.
Skip to 6:12 to start the Tec 9 portion:
I don't know why I didn't think of this before but the TNW PCC's I have work this way. They sell the same guns as either a pistol or a rifle. To make a rifle a pistol is just a barrel swap to the shorter barrel. They are saying nothing else changes. So the Mech-Tech would work the same way. TNW does of course warn you not to have in your possession a rifle and a pistol barrel unless you have also bought a pistol from them. Since if you get caught with them both (rifle and pistol barrel but no pistol) it "could" lead to you being charged. They also last I looked said they would not sell you a pistol length barrel unless you could prove to them you had one of their guns that was made as a hand gun. So anyway the Mech-Tech would work the same. Don't know why this did not click with me as I was very much thinking of buying another TNW in pistol form to use with one of the braces.
Is your buddy using a single stack or double stack 1911 and if single stack does it work well enough for him for the IDPA PCC division?
thats pretty much exactly what I was thinking of doing, too bad the listings finished so I can't get contact the guy.
Looking at BBTI (and including 45 super since there's only one entry for 460 Rowland) it looks like commercial ammo doesn't really gain much from a barrel longer then 10 or 12" so momentum shouldn't really be effected.
Weight doesn't really bother me that much, besides with 44 mag ballistics, weight is a good thing.
Saw this on another thread, how's this working for you, and who did you have cut it down and thread it?
Tom Denall did the cut/threading.
This thing is admittedly ugly but wicked effective.
It's an odd combo: Pistol Brace + CCU + 80% lower + suppressor and old red dot but it works, really really well.
I'll see if I can find out. I didn't shoot with his squad last time but I have his phone #.
I forgot. Maybe Saturday.
I talked to my friend today... His MechTech is actually for a Glock 17, which surprises me because he is a 1911 guy. However he got that because he could use the Glock 33rd mags with it. Apparently the Division Capacity for PCC is 30 rounds. A single stack would be at quite a disadvantage, yes?
Secondly, he gave an emphatic yes on the reliability being enough to shoot IDPA PCC with it. Said it is a bit on the heavy side tho. Which, having shot with my AR heavy varmint rifle, I think would be another disadvantage.
He mentioned that AR9 prices have been coming down and some are now on sale for $600, which is only slightly above the price of a Mechtech upper.

AR9s under $600
How long of a barrel did you end up with?
Well I found a sub2000 gen 2 for a decent price that should work reasonably well for PCC competitions, it fits nicely beside the bed and with a little practice my wife should be able to shoot it well. Still planning on getting the CCU though for more power.
We have 2 older units. A 1911 unit with an older gunsmith kit frame that used a framed frame so no adapter needed.
The other is a second one for a Glock 17 for the wife. On this one the length of pull was too long, so I shortened the butt stock by 9/16" , the most I could go.
I've shot both of them in steel plate matches and never had a hic-up.
On another issue I got to compare the 9mm against a Palmetto Arms 9mm on a AR platform, and a Colt AR9. The Mech Tech had far less recoil then both of them. It's a soft push against a sharp slam.
What's the weight difference between the CCU and the AR9?
The Mech Tech with an empty 33 rnd. mag weighs 7.315 lbs.
The Colt AR9 with mag weighs 7.675 lbs.
The Mech Tech has a massive bolt the measure about 6 1/ 2 " long by about 1 1/2" wide
The Colt has a standard bolt / carrier
You should enjoy that a lot. They are so short and light that for me they make a dandy home gun. The GenII fixed one of the big short comings of the GenI like mine. Much better sights. Is the one you bought a Glock mag model?
Yep, I think it can use any of the glock mags but I'm not sure, I can only get a 2 finger grip on it but my wife can get a full grip on it. Had to figure out a way that the wife could charge it but with that figured out she likes it too.
