What's the overall length?
Bob B on Jun 4, 2018
Is the barrel threaded? I'd like to drop the flash can and add a suppressor.
Cj B on Jun 30, 2018
BEST ANSWER: I didn't remove mine, but I'm sure it's replaceable.
I'd reach out to PSA for absolute confirmation, but yeah I'm pretty sure you can swap it out!
By the way, I almost threw down for another one of these!
Great price for this guy!
For my understanding, this is not considered an NFA item until assembled with the already registered lower?
Kelly M on Apr 28, 2018
BEST ANSWER: yes, only after you assemble it with a rifle lower, thus making it an SBR, will it be an NFA item. use it to build an AR pistol your good
does The barrel stick out far enough to attach a suppressor ?
Ray M on Jun 21, 2018
BEST ANSWER: dont have a suppressor to try this with but looking at my upper the hand guard extends approximately 2" past the end of the barrel. so if you have a suppressor the same dimensions as the flash can then you can, if not then most likely not, the hand guards sit within a 1/4" from the flash can. so it is a very tight fit.
Would the Silencerco Saker 762 (1.5" diameter) fit under the handguard?
Kelly M on Apr 28, 2018
BEST ANSWER: No, however I did Mill mine out to accommodate an AAC ti-rant 45. It’s about the same size I think. A machinist can do this for you with no problems.
I am in the process of starting a A.R. pistol build. Can I legally possess an upper before I own a registered pistol lower? I already own a registered rifle lower.
Robert L on Jul 5, 2018
BEST ANSWER: Enter an answer to this question.If you have an AR rifle lower and no pistol lower, then absolutely NOT!
How long before it's back in stock?
Craig Z on Apr 24, 2018
BEST ANSWER: Lead times on getting products back in stock will depend on production and demand. I would recommend signing up for the back in stock alerts at the top of the product listing. This will notify you as soon as it comes back in.
Anyone know what the internal diameter is of the handgaurd?

Very happy with it.
Well made and happy with it so far. I will update this after I put 1000 rounds through it.

Best deal I’ve ever got on a complete upper
Caught it on clearance for $269 with free shipping. Unbelievably good deal. Not a single hiccup. Couldn’t be happier.

Magpul AFG...FAIL
Magpul AFG will not mount to this handguard without screw contact to the flash can or the gas block or both. M lok hardware will not spin to position at the flash can area due to lack of clearance. I had to grind a screw to clear the gas block. I was careful on the initial attempt, but still ended up marring both the gas block and flash can. What a shame. No way of positioning the AFG and be able to miss the can or block. Attention to detail PSA, come on.

WOW! Excellent upper!!
Added this to an Anderson lower and it fits and matches perfectly. Ran about 100 rounds through it with NO issues Flash can pushes blast and sound forward making it a pleasure to shoot.
July 28, 2018
Great upper!
Works like a charm, I have about a 100 round they this upper and it’s flawless!

Mated this to a Savage stripped lower. Unsure if it’s the upper or lower but there is a slight amount of play. Have yet to test fire it but I love it.

Came fast

My 300blk pistol build.
This is a very solid and fun upper, I sighted in at 50 yards and was getting 1” groups with budget 125gr 300blk ammo, at 100 yards I was getting very respectable 2-3” groups with an RDS, I have no doubt with better ammo and a magnified optic I could get much better results but this isn’t a “target” build so I’m getting exactly what I wanted from it, a small fun package to reliably send lead down range and it does that very well.
PSA 7 1/2” upper on a PSA pistol lower with a SB3 Brace, I added an RDS and a cerakote camo job.
