Does this kit cycle well? Any problems cycling ammo?
DavidMartinez on May 5, 2019
BEST ANSWER: No problems at all. I have shot subsonic and supersonic through this upper suppressed and non-suppressed.
Is this the entire gun just needs assembling? Or if not what's it missing?
ViolentJ69 on Apr 9, 2019
BEST ANSWER: you also need a bare lower
Preferred optics for this unit? Yes it is looking for recommendations.
Charlotte H on Mar 23, 2020
BEST ANSWER: I like the Sig Sauer Romeo 6 with shake awake
because its always on. I don't like a red dot that must be turned on. Mine has rode in my vehicle for more than a year with the original battery and its still on. I am intentionally leaving it in to see how long it lasts, after that I will change it annually.
Are all parts included new?
Jimmy on Apr 12, 2019
BEST ANSWER: Everything but bare lower, mag and what ever sighting system you want.
Is the muzzle device pinned and welded or just ”loctited” on the barrel?
Jordan R on Apr 8, 2019
BEST ANSWER: No pin, no weld just standard crush washer. Mine was snug but three raps with the palm of my hand on a AR tool had mine spinning off.
is the upper of this kit completely assembled?
garry k on Apr 8, 2019
BEST ANSWER: yes, ready to go
does this kit have the upper barrel Assemb. assembled , put together as one piece ?
garry k on Apr 8, 2019
BEST ANSWER: Short answer YES the uppers come completely assembled
Is the bolt carrier chromed ?
Haysop on Apr 8, 2019
BEST ANSWER: Not the exterior of the bolt carrier, if that is what you are asking, interior I believe it is. They do have a similar kit with NiB (nickel boron coated) bolt carrier although it has a higher price tag of course.

Pleasantly Surprised
Wasn't sure what to expect for accuracy but this little unit is capable of 2" groups at 50 yards with a holographic sight.

7.5 inch 300 Blackout.
Would give a 5 but have not been to the range yet. I use a red or orange tape on weapon and magazine to prevent me or anyone else using the weapon from placing 5.56 instead of 300 rounds.

Bunch of gun for the bucks
Great build on PSA lower. I installed a Law Tactical folding stock, now 17 1/2 inches folded. Nice crisp trigger (not perfect but way better than milspec). SBA brace was tight to slide but broke in with a little time and oil. Put a 2X shotgun/slug gun red dot on the rail. Rings 2" metal targets at 75 yards. Cycles 220 subs with suppressor no problems. Mine doesn't like to cycle 220's without a suppressor. Supersonic ammo, this thing is honey badger (it doesn't give a shyte) and eats anything. I waited until the price was 349, so that's pretty much a steal

Great value!!
Very nice kit! It fits nice and tight on a discontinued magtech magnesium alloy lower. Works great with a suppressor as well. No problems with my aac 762sdn6. This is the shortest barrel that the suppressor warranty will allow. The pistol brace is sweet, adjusts like a standard stock. All good things

Perfect for what I wanted to begin my supressed 300 blk pistol build with. Fit and function are flawless, will buy similar kits in the future.
Very impressed with this budget build.
