Why does it have a pistol length gas system? What’s the benefit if you are wanting a rifle?
Benji H on Nov 25, 2019

The 300 Blackout was designed around a pistol length gas tube. From our testing we have found it to be the most reliable gas length for this round.

If I already have a stripped lower, would this kit include everything else I need to finish my rifle?
Jerry D on Dec 26, 2019
BEST ANSWER: You will also need a magazine, a sighting system and ammo.
It says pistol length, but it looks like it has a rifle stock; so which is it ? Is it a pistol or rifle?
Marco S on Dec 24, 2019
BEST ANSWER: It's a rifle. Pistol Length refers to the gas tube length.
Does this require a tax stamp? I’m confused on the length in the description.
ethan p on Dec 5, 2019

No, you will not. This upper has a pistol length gas tube.

Will this build support shooting supersonic 300 AAC rounds or subsonic only?
Kalab C on Dec 2, 2019
BEST ANSWER: it will handle supers fine
Is this an ar15?
Jonathan D on Apr 4, 2020
BEST ANSWER: Yes, it's an AR15 platform in a 300 Blackout cartridge. The 300 blackout is a shorter necked down cartridge case than your standard 223 round. Good out to about 300 yards.
What thread size is used for the provided flash hider?
Jeepjohn on Mar 31, 2020
BEST ANSWER: The same for .308. 5/8”-24
Do you have to be 21 since its a pistol or is it still considers a rifle ? Ohio rifle laws are 18 just wondering might have to cop this if so.
mitchel m on Mar 13, 2020
BEST ANSWER: It is a rifle, notice the rifle butt stock?
I don't see a trigger gard...is it included?
Joe S on Jan 7, 2020
BEST ANSWER: Yes, a basic trigger guard is included in the kit.

To the range, once my scope comes.
Haven't fired it yet but the feel of this is great, nice and light. Can't wait to take it to the range.

Great shooting set up
Went together easy. Shoots well, sighted in with SuperSonics and got about a 1 inch group. No malfunctions, but charging handle would come open/unlatched while firing, but PSA sent a new one and its been good. Looks great with an Aero precisión lower. Tried with a can (omega 9k) but a little louder than a bolt 300 blk, but probably awesome with a full length .30 cal can. Happy with the purchase & will buy from PSA again.
3 shot group with SuperSonics (Fiocchi 125 grain)
Put it all together with an Aero Precision lower

Great value. Great quality.Nice MSR.
I would highly recommend this. No problems at all assembling it. Runs great. Combined with my K.A.G. lower it's one of my favorite rifles.

Just had a striped lower and this kit came with all the parts to have a complete 300 blackout. Just throw a optic on it and it’s ready to shoot!

2nd PSA 300 BLK build
4th build in 4 months with PSA. This is my second 300 BLK build. Pistol length gas block is perfect for subsonic blinking. I installed a enhanced fire control group. Sweet shooter! That is a Anderson lower. I need to stay with PSA to acquire matching color between the upper and the lower.
Vortex optics
Slight color difference
