About This Firearm
The Palmetto State Armory PA-15 is a semi-automatic AR-15 in .300 Blackout built as the cheap way into the cartridge. It has an MSRP of $599.99. It ships with a Magpul MBUS sight set and a 30-round PMAG, so it can be aimed and loaded the day it arrives.
The barrel is 16 inches of 4140 chrome-moly in a heavy profile with a nitride finish, on a pistol-length gas system behind a low-profile .750 gas block. Both receivers are forged 7075-T6 aluminum, hard-coat anodized, and the handguard is PSA's lightweight M-LOK free-float rail. The stock is a six-position Magpul carbine unit, and an A2 flash hider sits on the muzzle.
If you're cross-shopping, the used Ruger AR-556 in this chambering is 6.40 lbs against this rifle's 6.75 lbs, states a 1:7 twist and a 5/8-24 thread, and has a heavy cold hammer-forged barrel, though it came with no sights. The CMMG Dissent Mk4 has an MSRP of $2,149.95 and weighs the same as the Ruger, with a folding stock, an adjustable gas block and two magazines. Measure the rifle before buying a case for it.

Strengths & Limitations
- PSA states a full lifetime warranty that extends past the original purchaser and covers shipping both ways, so a used PA-15 is still covered.
- The handguard free-floats the barrel, so a sling or a bipod does not bear on it.
- The gas block is a low-profile unit, so the handguard runs its full length over the top without a cut in it.
- The fire control is a mil-spec single stage, so a lighter trigger is an early purchase.
- The A2 flash hider has to come off before a suppressor goes on, so measure the thread underneath before ordering a mount.
- The MBUS rear sight shares the receiver rail with an optic, so a red dot and the flip-ups compete for the same space.

Frequently Asked Questions
How does it differ from the 5.56 PA-15?
PSA builds both. The 5.56 version carries a 1:7 twist, a 1/2x28 thread and an A2 front sight base with a carry handle, where this one has a flat-top upper and flip-up sights.
What does a pistol-length gas system mean for a suppressor?
More gas back through the action. A can raises port pressure further, and with no adjustable block here the fix is a heavier buffer or a different spring.
Does it take standard AR-15 magazines?
Yes, the same ones a 5.56 AR uses. Keep the two calibers' magazines marked, because a .300 Blackout round will also chamber in a 5.56 barrel.
