Does the rail have qd sling attachment points?
Mackenzie C on Sep 7, 2019
Would this be considered a rifle or pistol when fully built?
Marcus H on Sep 7, 2019
BEST ANSWER: It would be a pistol and need a pistol brace. In order to be an SBR (short barreled rifle) you need to submit paperwork with the ATF and get it approved to put a rifle buttstock on it.
Is this a carbine or mid-length gas system?
TideMan on Oct 3, 2019

This has a carbine length gas system.

Good alternative to the 10.5
Not having any reviews at all had me concerned. But i've been lucky and never had any issues with any of my PSA uppers so i figured id give the 11.5 a shot. I received it within a week, no blemishes, upper receiver has a nice tight fit to a Spikes lower. Handguard screws were only snug, which is fine because I prefer to take them out and loctite them anyways. A warcomp and a few coats of rattlecan and went to the range. Only had a chance to put 500 rds through it, and no issues. Shooting M193 and seeing 3 MOA on average. Good enough for me. I will follow up review once have more rounds through it. All in all, good buy so far
