Do you need a special magazine for the 300?
Travis R on Oct 30, 2018
BEST ANSWER: No. The 300 AAC blackout uses the standard AR-15 magazine. Take care not to use 5.56 ammunition in it, though.
Will I need to purchase a lower kit?
anthony on May 31, 2018
BEST ANSWER: No. I dont think so. Take a hard look at the picture. This is a complete kit but does not include the stripped lower you will need to provide that yourself. The stripped lower, meaning a lower with no parts in or on it, is the actual gun under atf rules. They can't ship that to you. You either need to make your own from a 80 percent lower, which can be shipped to you, or buy a stripped lower from a FFL.
Can I add iron sights to this? If so, which ones?
Joshua S on Jul 21, 2018
BEST ANSWER: You can add any pop up iron or poly sights that will fit a standard pic rail
What does the pistol nomenclature mean in the description?
PopJack on Oct 25, 2018
BEST ANSWER: It has a pistol length gas system.
Would this be considered an sbr considering it's overall length is only 24.5?
Jay R on Dec 4, 2018
BEST ANSWER: No. This is an upper receiver and a lower parts build kit. When the lower part kit is installed into a lower receiver (supplied by you, because it needs to go through an FFL), it will be well over 26".

Excellent choice!
So my muzzle break was not aligned properly when I got this upper. The ports should be parallel to the earth on left and right and perpendicular out the top. It was about 15 degrees off such that the left side is angled downward... OK that's not a hard fix... Other than that it's 'bee you tea full' ... I love my 300 AAC BO. I bought a bunch of subsonic ammo for it and hope to a silencer so I can have fun at the range without the noise. Our local ranges are small, one is it 200 yards the other is 600 yards. 300 BO does well enough in those ranges for me.
It's a small & medium game hunter, especially with the supersonic rounds. And it's a quiter hunter with the subsonic rounds, but will reduce the usable range. But even at subsonic speeds the 30cal round is an excellent hunting round for the range at which most hunting's gets happen, which is under 200 yards.

300 Blk Rifle Kit
The upper looks good. Shoots well. I had zero malfunctions.LPK works well also. Detent and springs are stiff but will wear in with use.

Ended up on this billet 80% lower that I completed

Great kit
250 rounds through it so far 0 malfunctions. Trigger is surprisingly decent for mil spec. This will be the first of many psa builds my wallet fears.

First build of mine is the PSA 300 blackout. Very acurate and shoots awesome. I will be building another PSA soon since I’m happy with my first build. Way too go PSA!! Can’t beat the pricing with the accuracy! Too be honest I wasn’t expecting a good shooter for the price! Pleasantly surprised and can’t wait too build another in an 308!!
Really happy with my 300 Blackout! Shoots great and very acurate!
This group was with my PSA 300 Blackout! First three rounds in same hole
