Building a 9mm AR...how dependable is using an AR15 lower with a magazine adapter?

You will be glad you did. The RDB is much smoother than a blowback 9mm. The endomags are super slick too.
USPS just delivered the Endomag innards this morning and I installed them into 2nd gen PMags...this is a slick design ...they also delivered an order of 500 124 grain plated 9MM bullets from Accura Bullets...now while waiting for the upper to arrive, I’ll get to loading. One question though...does your upper favor any type of load ie. bullet weight, powder or velocity?

I have only shot mine with WWB 115gr and my own handloads. 125gr Precision Delta bullets (polymer coated), loaded with green dot powder to make minor power factor out of my USPSA guns. Both loads shot very well.

UPS delivered my CMMG upper today...I mounted a Vortex 1X Spitfire scope off an extra rifle upper I haven’t used in a while...put the whole shebang on my pistol lower and hope to head out to the range this weekend for some 9MM fun

Am I reading this right, Endomags and a 9MM upper is all that's needed to convert a 5.56 AR to 9MM ?

You’ll want a 9mm buffer as well.

Assuming the CMMG is the only upper which can use the standard 5.56 buffer?
If it's that simple, CMMG upper and Endomags... I'm in.
Developed in collaboration with Mean Arms, CMMG’s 9 AR Conversion magazine is designed to allow a standard M16/M4/AR15 lower to run 9 x 19mm Luger ammunition with the use of a CMMG MkGs 9mm Radial Delayed Blowback operating system upper group. The 9 AR Conversion magazine is not a .223/5.56 to 9mm conversion kit. The 9 AR Conversion allows owners of standard M16/M4/AR15 to purchase a dedicated CMMG 9mm MkGs upper group. The 9 ARC and MkGs upper groups are designed to be compatible with M16/M4 full auto lower receivers. The 9 AR Conversion utilizes a MagPul PMAG® 30/AR/M4 GEN M2 MOE® magazine body.
NOTE: The lower receiver should run a standard carbine buffer and action spring for reliabThis message has been edited. Last edited by: Bisleyblackhawk,

I was thinking same thing until I saw the Endo mags are $30 a pop, you could get 2 Colt style mags for that price. I think a Spikes colt style lower has my name on it soon.

I bought a de-milled Colt 9mm machine gun which contained everything except the lower. One of the main things that attracted me to it, was it came with a factory 3-round burst ... which I used 2-3 times and got bored with and put it in a bag some where. However I still shoot the Colt 10.5" upper, with the matching bolt & carrier, buffer as well as the Colt mag block and was supposed to come with 2 Colt mags which turned out to be something other than Colt, but they worked fine.
Being de-milled, the mag block had the rivet holes drilled out, but it also had a screw in the bottom that when tightened would push out to pistons to lock it into place.
I've used it on different SBR'd lowers and my M16 and have never had a problem with it
If you really want something you'll find a way ... ... if you don't you'll find an excuse.
I'm really not a "kid" anymore ... but I haven't grown up yet either

I think I like the complete CMMG Banshee 300 with the Glock lower...
$1550 is steep but not terrible.
