Will this work with standard mil spec AR-15 lower? Or requires 9mm specific lower?
Clint on May 6, 2019
BEST ANSWER: There are special magazine internals for 5.56mm PMAGs that allow you to convert them into 9mm magazines, so theoretically yes. Dedicated 9mm lowers may or may not run smoother.
Can you just take off a 5.56/223 20" rifle upper and replace it with this 16" 9mm upper with a magazine adapter and start shooting or is there other parts that need replacing (as buffer or spring)?
Gill T on May 8, 2019
BEST ANSWER: You will aslo need a 9mm buffer. As far as the magwell adapter, Mean arms makes an endomag that replaces the internals of a Pmag and has worked flawlessly for me.
Will this 9mm upper be compatible with this 516445843 PSA 556 lower using a mag adapter ?

Will this work with mil spec AR-15 lower or does it require a 9mm lower specific? Thanks.
Clint on May 6, 2019
BEST ANSWER: It will work with a mil-spec lower. All you need to change is the buffer . 9mm is heavier than 5.56
Should this upper work with a mil-spec lower assy and a magazine well adapter using Colt-style magazines? Thanks!

Does the bolt lock back with last round?
David G on May 14, 2019
Does the bolt accept glock mags or colt or both?

Well made for the price
My first 9mm AR and it fires very well combined with mean 9mm conversion magazine. I attached this with Palmetto lower receiver and it fits like a glove.
