Hey folks,

Saw this in a Brownells ad toda:

How does this work on the AR platform?  I don't see a place for a gas block or any way to have it cycle the action.

Most 9mm AR's are blowback and do not use a gas system like a regular AR.

Interesting.

Does this require a specialized buffer system?

How about the upper unit?  Is there a specialized upper that has the gas tube hole plugged somehow?

The lower and bolt are caliber specific. The bolt is actually one piece.

The upper can be regular AR15 and typically the gas tube hole is left as is.

The buffer systems vary, but you can use a conventional system with a 9mm buffer.

dont you need a stamp for one or those? serious question

not for the ar pistol.  If you configure as a rifle it's a short barreled rifle and you would.

And you can hunt with it

Too soon?

Cool.  So you get a lower that can handle the 9mm mags(I have seen some that take glock mags), and then you put a standard upper in with a traditional buffer set up and a 9mm BCG, and put the barrel on and it should cycle without the gas system?  That's pretty slick

I've seen a 9mm carbine that had similar look and feel to an AR on a real popular you tube channel hickock45. The cost was $500 ish and seemed pretty decent straight blow back design and offered in a bunch of Glock calibers as it used those mags.  Pretty sure 9mm was designed for sub machinegun/carbine use...
Pretty sure they were being used in 3 gun competitions too.

Mech tech carbine upper for your glock.

Also Just Right Carbine for an off the shelf complete gun in 16" barrel and they are in the $5-600range, come with 1 or 2 mags.  They are great running guns, but no BHO on empty mag.

I recently bought a CZ Scorpion and sold my 9mm AR, just like the scorpion better.
