Palmetto State Armory Sabre 300 Blackout Pistols
The PSA Sabre series of firearms has been a hit among shooters looking for high-quality components straight from the factory. After the success of the Sabre .308 and Sabre 5.56, PSA is now expanding the lineup with a 300 Blackout option, ensuring that enthusiasts of this caliber get the same premium treatment.
Built with top-tier materials, the Sabre 300 Blackout Pistols come packed with upgraded features that make it a standout option for home defense, suppressed shooting, and general range use.

Suppressor-Ready & Built for Versatility
PSA designed the Sabre 300 Blackout Pistol with suppressor users in mind. The adjustable gas block makes tuning for subsonic and supersonic loads effortless, ensuring smooth function with or without a suppressor. PSA demonstrated the system’s performance using an AAC Ranger 7 suppressor and AAC subsonic ammo, proving its reliability in real-world scenarios.
Why Choose the Sabre 300 Blackout Pistol?
This AR pistol is built to handle anything from personal defense to hunting to tactical training. With a forged 7075-T6 upper and lower, a mil-spec anodized finish, and battle-tested PSA components, it’s a firearm that can withstand hard use and still deliver top-tier performance.
This pistol fills a real, practical gap for shooters who want an AR-platform gun that’s compact, hard-hitting, and built to run suppressed. The 300 Blackout round shines at short to moderate ranges and with heavy, subsonic bullets — so if you like quiet range sessions with a can, hog hunting in thick brush, or a compact rig for close-quarters defense, this makes a lot of sense. PSA loaded the Sabre with parts you’d normally pay extra for (quality BCG, tuned buffer system, Hiperfire trigger, adjustable gas block), so you’re getting a factory gun that’s already optimized for those roles.
What else it’s good for: training, suppressed plinking, and any mission where a short, controllable cartridge is preferable to a longer-range round. It’s also a great platform for customization — optics, lights, and handguards bolt right on, and the adjustable gas block makes switching between subsonic and supersonic loads painless. In short: if you want a compact, versatile AR that’s ready for a suppressor and built from solid components, the PSA Sabre 300 Blackout pistol is an easy box to check.
For those looking for a factory-built 300 Blackout AR pistol with top-shelf components, PSA’s Sabre 300 Blackout Pistol is a no-brainer. Get ready to experience American-made performance and precision engineering, all at an unbeatable value.

Old article. I have pistols that have 8 inch barrels. If I were to shoot a rifle cartridge in pistol form the minimum I would want is 10 inch otherwise to me it seems like a waste.
People can knock PSA all they want, but they deserve credit for building rifles every man can afford and helping put America’s Rifle effectively into common use (that precedent is unconstitutional, but that’s a discussion for another time). It doesn’t get much more patriotic than that. Plus, their stuff isn’t that bad and they are upping their game.
I’m confused…why is this called a pistol, when it has a shoulder stock and a fore grip, and not a short bbl rifle? I’ve seen this quite a bit lately. While there is something for everyone, making this hobby great, it’s not for me. They’re too effing loud without a quality suppressor (another $700 easily wo tax stamp next yr), the bbl is too short to burn all the powder thereby losing velocity (but it looks awesome with that 20″ flash out of the muzzle), and they’re of limited precision at distance. Yeah, it might be great for home defense,… Read more »
In the video, why is the demonstrator wearing muffs? Is it because the music is too loud?
The video says the barrel is 8.5″ but the article says 10.5″
The video says the rail is 6.75″ but the article says 10″
The video says SBA4 brace but the article says SBA3
The video shows brown but the article’s embedded image is black
The video is talking about one product but the article is talking about a different product
I’m not buying any “large format” pistol or anything with a pistol “brace” until the GOP FINALLY fixed the pistol brace issue, permanently… Like disposing of the ATF for instance, and tearing up the NFA.
It’s too much money to spend with every administration having a different “interpretation” of 2A.
Until Trump, Patel and the GOP clean up the ATF and this damned pistol brace thing is settled, I’m buying any… shall we say, BIG pistol.
Also, the external piston and the .300 Blackout’s a no go from me.
Battle tested PSA components…

I’ve never read anywhere that PSA has government contracts. Actually I’ve read and head the owner say in articles and videos they DO NOT have government contracts. Therefore, how can they have “Battle tested PSA components”?….
