Description
Hi-Point made its name keeping firearms affordable, and when the company jumped into the AR game with the HP-15 line, it did it the right way. This is not some proprietary oddball. The .300 Blackout HP-15 pistol is built on forged 7075-T6 aluminum upper and lower receivers with genuine mil-spec internals, so the charging handle, bolt release, and magazine release all feel exactly like every AR you have ever handled. Aftermarket parts drop right in, which makes this a great base gun for anyone who likes to tinker or upgrade over time.
Why .300 Blackout Makes Sense in the HP-15 Pistol
The .300 Blackout cartridge was designed from the start to run out of short barrels, and the 10.5 inch tube on this pistol is right in its sweet spot. The 4150 chrome moly vanadium barrel wears a 1:7 twist that stabilizes everything from fast supersonic loads to heavy subsonics. The muzzle comes threaded 5/8×24 with an A2 birdcage installed, so swapping to a suppressor or a different muzzle device takes about a minute. Pair it with subsonic ammo and a can, and you have one of the quietest semi-auto setups you can build without going to a dedicated integrally suppressed gun.
Handling and Setup on the HP-15 .300 Blackout
At 4.25 pounds unloaded, this thing is easy to move around with, whether you are working a range drill, keeping it handy on the property, or hunting hogs in tight brush. The 9.5 inch free-float M-LOK handguard gives you plenty of room for a light, hand stop, or sling mount, and the full-length Picatinny rail up top is ready for a red dot or LPVO. There are no sights from the factory, so plan on adding an optic. A blade-style stabilizing brace comes standard, and a 90 degree manual safety keeps operation simple and familiar.
What Backs Up the HP-15
Every HP-15 carries Hi-Point's limited lifetime warranty to the original purchaser, which is not something you see often at this end of the market. The pistol ships with one 30-round magazine, a cable lock, and a chamber flag, so it is ready for the range as soon as you top the rail with an optic.

Frequently Asked Questions
Is the Hi-Point HP-15 compatible with standard AR-15 parts and magazines?
Yes, and that is one of its biggest strengths. The HP-15 is built on forged mil-spec upper and lower receivers with standard controls, so common AR-15 triggers, grips, handguards, and other components will fit. It also runs standard AR-pattern magazines, though as with any .300 Blackout gun, some 5.56 magazines feed the cartridge better than others.
Can I run a suppressor on the HP-15 .300 Blackout pistol?
You can. The 10.5 inch barrel is threaded 5/8×24, the standard thread pitch for .30 caliber cans, and the factory A2 birdcage spins right off. The 1:7 twist stabilizes heavy subsonic bullets well, which makes this pistol a natural fit for suppressed shooting.
Does the HP-15 pistol come with sights?
No, this model ships without sights. The flat-top upper has a full-length Picatinny rail, so mounting a red dot, holographic sight, or magnified optic is quick and easy. Most buyers pair a short AR pistol like this with a red dot for fast target acquisition up close.
What kind of warranty does Hi-Point put on the HP-15?
Hi-Point covers its HP-15 line with a limited lifetime warranty for the original purchaser. If a defect in materials or workmanship shows up, Hi-Point will repair or replace the firearm at their discretion. That level of backing is rare on a budget-friendly AR platform.
