I'm telling you it sounds like a guy that posted on GlockTalk about being some super mall ninja that wanted to carry MP5 for security. There was a thread on lF about it but cant find it right now.

BWAHHHHAAAAA!!

Okay, mall ninja stuff aside...

I am curious about a .40S&W AR weapon also as I have a ton of it & think it would be a cool toy. I am not an operator/mall ninja/special forces/SEAL/Green Beret/GSG9/SAS/Spetznaz type so I won't be going in to combat with it so I'm not worried about terminal ballistics, stopping power, etc. I just enjoy shooting and would like something other than a 9mm AR.

What mags would it use (I'm unaware of any subgun based in .40 other than the MP5 10/.40).

Any suggestions? Anyone???

Olympic Arms makes one in .40 S&W AR that uses Glock mags. I have their 9mm version that uses Glock mags.. It took some work to get it to function/ eject but I have been pleased for the last 2500 rounds. Try their site.

Interesting. What kind of work are you referring to? I am curious as I'd like to go with a .40 S&W AR but so far have been pretty disappointed with what is out there. I am most likely going the AR45 route but as mentioned I have a ton of .40 that would be sweet in a carbine.

Thanks for responding so quickly, BTW!

Re: AR45 in 10mm/.40.
On the CNC AR45 forum there is a guy who, IIRC, got his to work with 10mm using GG mags. Might be worth the searching to find him and see what he did. I do seem to remember him having to do some work on the feed ramp was about all.

Polished / deburred the BCG, installed a lighter buffer spring, polished all contact surfaces, and experimented with ammo brands. I keep it clean and it will run any major brand 9mm. It does not like the cheap dirty stuff. It's a blowback action and the unburnt powder and carbon clogs it up quickly. The brand name stuff works fine.
