Will this kit work with a folding stock adapter and Anderson ghost power?
Stewart V on Nov 7, 2018
What is the full length after put all together?
RICK13 on Dec 10, 2018
BEST ANSWER: With the brace fully collapsed, 23 1/4" to the front of the muzzle device.
With it being so short can you fit an angled foregrip on this rail without much modification?
Jonathan H on Feb 27, 2019
BEST ANSWER: Short answer no. The Magpul angled fore grip will interfere with the angle on the rifle hand guard and the gas block is directly beneath one of the two M-Lock slots. However, I have a suppressor on mine so I installed the Magpul angled fore grip "backwards" and just use the one forward M-lock slot. In this configuration, it'll definitely keep your hand off of the very hot suppressor.
Can this model be suppressed?
Chris on May 30, 2019
BEST ANSWER: Yes I have a buddy that shoots sub sonic's out of it he said that its excellent. Thats why i built this one. But, i haven't asked if he needed an adjustable gas block.
Will this kit be able to ship directly to my house? Or does it have to be shipped to my local gun shop or someone with an FFL?
Nathan on Feb 27, 2019
BEST ANSWER: The lower receiver is the serialized part of an AR-15. If you just buy this kit, it can ship directly to your home. If you buy a lower receiver, it will go to an FFL and you will have to do a 4473 for it.

This kit is awesome
Built this on a savage lower I picked up at academy and the fit is outstanding. Only have about 150rds thru it so far and it's great. At first had some mag related feed issues but once i got some actual 300blk mags, haven't had anymore problems. Love the trigger and bolt group along with the nitride finish. Well worth the up charge. I really wish ammo was cheaper because i love shooting this thing. It's a little beast tho, love it
Next to my Armalite m15 for size comparison.  This thing rocks!

Not worth the money.
When I received this kit it was missing the hammer. I had to make several calls to PSA to get them to send one to me. This took several weeks to get it done. Also the Mlok slots on the handguard are useless because the gas block is underneath them. I had to buy a different handguard. Then the barrel nut took a three foot pipe and wrench to break free in order to change handguards. Way more then the suggested 80 ft. pounds of torque. Overall this kit was not worth it even on sale.

Get what you pay for I guess? If you like crooked gas blocks then this is the upper for you!
At least it shoots... But the craftsman is not there. Who ever pinned this gas block should get glasses...

Looks great but doesn’t work!!!!!
Bought this kits and put it together without a problem......I thought. Went to the range and had nothing but problems. Fired 3 rounds and then the rifle stopped going into battery. I used the forward assist for the next 2 rounds and then the big issue showed up. The bolt seized into the chamber. I got it unstuck and removed the mag. Closed the bolt and to my surprise, the bolt seized shut again.

After getting the BCG out. I placed a different milspec BCG into the gun. This one from a very expensive company based out of the low country of SC. Guess what, the same thing happened. BCG stuck in the chamber. Then I tried a S&W BCG. It got stuck too. Put the PSA BCG in my DD and S&W, both ran like a champ.

After my testing. It is obvious that the problem is with the completed upper that was assembled by PSA. I don’t know if it is a head space problem or something else. It really is a shame because this thing looks and feels awesome. I just hope PSA makes it right and I finally get to shoot my brand new rifle.

Awesome 'lil Package
Everything you need in a small package less a stripped lower. Assembled in 30 minutes. Bought this after the excellent results of an 10.5" 300BLK kit. Amazed at how these little guys print with 120-186 gr loads. Haven't shot them over 50 yards yet but they are cutting one ragged hole even with the different bullet weights! Excellent Entry or Home Defense weapon - "Repel Borders!!" Great with a laser and/or red dot sight.

A really nice kit!
I was very impressed with this kit. The nickle boron finish on the trigger, hammer, bolt carrier and bolt gives it a very smooth feel. The parkerized finish is a even dark black the matches my Rock River Arms lower very well. I’ve only shot supersonic round through it so far with no malfunctions and it’s darn accurate to boot! The fire control group was finnished well and went together easily, no burrs and no slop. I liked that the take down pins were center drilled to use a bulitt point to push then out on a tight receiver. It’s also cool how they bag the bolt hold catch assembly in one bag, safety group in another, etc... so if this is your first AR build you shouldn’t have any difficulty after watching a couple of YouTube videos.
Sighted in with my elbows and magazine resting on the bench.
