Is there an adapter available to convert to 1/2 x 28 threads,... as are most 9mm cans???
Robert B on Apr 16, 2019
Got one of these recently. The handguard is an M Lok but I can’t see how a rail could attach as there doesn’t seem to be any room with the flashcan? Anyone mounted anything to the sides or bottom of the handguard?
AJ2248 on Feb 18, 2019
BEST ANSWER: no, the flash can doesn't leave enough room to allow m-lok mounting hardware. Everything is on the pic rail.

PSA 9 mm-what a blast
I oiled the bolt a little and put some grease where I had some wear on my other PSA pistol and put 200 rounds downrange. One round would not load in the chamber. Since I tried a couple of times I'm gonna charge that problem to the ammo and not the pistol. 100% reliable. Accurate as all get out too!

OAL = 23"

Lots of fun.
Pulled this little gem out of the box, put some oil on the bolt and ran over a hundred rounds through it completely issue free. Ran with the ETS mags also. For my first pistol caliber AR I’m liking it.

Reliable Weapon
Runs perfect with Glock Magazines. Well built quality firearm
February 17, 2019
Yes! Do it!
This is an awesome little piece with a great price tag. There's a little wiggle between lower and upper but nothing awful. The shockwave brace would probably be better as an sb brace (at least) but out of the box it's still a wonderful little cqb option.

The stock mag isn't great. If it wasn't for that mag id have given it 5 stars, but it's compatibility with glock makes that a small issue.

*HAD PROBLEMS WITH FRANKLIN BFS* safety doesn't work. Everything else works fine.
