What are the dimensions for clearance inside the handguard? In other words, would you have clearancr to attach a standard 300blk suppressor to this upper?
John T on Jun 6, 2018
BEST ANSWER: There is not enough clearance to mount my AAC SR-7 surpressor inside the hand guard. However, after installing an extended length O ring on the threads, the QD mount for my surpressor was extended past the hand guard enough that I can fully secure my surpressor to it. Hope this helps
Will a direct thread suppressor attach without any issues? Can't see if the threads are extended out past handguard.
Daniel H on Jul 12, 2018
BEST ANSWER: No if you have a Silencerco you can use the compensator for the quick attachment.
You could also trim back the hand guard.
What kind of buffer tube should I use with this one?
Robby on May 10, 2018
BEST ANSWER: Either pistol or carbine length buffer tube will work. I have the KAK Shockwave brace and tube on mine.

PSA for the win!
For the price, the quality is outstanding. 170 rounds thus far, no issues. Super light handguard, modestly heavy barrel and BCG but all around a great upper, especially for the money. Definitely getting a PSA upper for my next build. PSA makes gun building super easy for the everyday man. GOD BLESS AMERICA

My first AR pistol!
Went together easily. 300AAC upper and the SBA3 brace. Added the Vortex Sparc with Magpul 10 mag deal to round it out.
The only part I've upgraded is the the pistol grip to Magpul. The rest of this is PSA, very happy.

Great fit, finish, and function
Ran flawlessly over 200 rounds. I kept switching between my 5.56 pistol lower. Now I have a 300 dedicated lower. But definitely worth it

Sturdy, good looking, goes bang every time.
Goes bang every time with supersonic rounds. Will have to adjust buffer to get subsonic ammo to work unless using a suppressor.

Back 2 back
Got it in, inspected everything... Bolt carrier group was terribly finished. It felt like 120 grit sand paper. Called psa immediately, I sent it back. 3 weeks later another one arrives. Nearly the same condition as the first. I used sand paper and steel wool to smooth everything up myself instead of sending it back a second time, I really just wanted to shoot the gun I purchased almost 2 months ago... Never had an issue with psa up to this point quality control could surely use a looking into since this was not a blem purchase

Great gun! Along with a psa lower build kit, iv got this thing running great!
