Description
H&R's Commando is one of the more interesting AR pistols to come out in recent years, and that's not just because of how it looks. Built around the Colt 733 design, which itself is an evolution of the Vietnam-era XM177E2, this pistol packages a serious .300 Blackout platform into a compact, retro-styled build that actually holds up to scrutiny under the hood. The 10.5" barrel is made from 4150 Chrome Moly Vanadium steel with a Parkerized finish and a 1:8 twist rate dialed in specifically for .300 BLK, running a pistol-length gas system. Upper is a C7 with M4 feed ramps, the lower is marked M16A2 and dedicated to .300 Blackout, and both receivers are forged 7075-T6. The bolt is Carpenter 158 steel on a full-auto-profile BCG, and the trigger is a standard mil-spec group. Nothing exotic, but everything correct.
What Makes the H&R Commando Worth a Second Look
The carry handle on this pistol isn't just a styling choice, it's a fully functional A2 unit with built-in iron sights that work out of the box. The barrel is threaded 5/8×24, so adding a suppressor or muzzle device is straightforward. The HAR-15 adjustable pistol stabilizing blade gives you a six-position buffer tube to work with, and at 6 lbs configured, the Commando stays manageable even with a full 30-round PMAG loaded. The Kino-style gas block tucks neatly under the carbine handguard, keeping the profile clean and period-correct.
Running .300 Blackout in the H&R Commando Platform
.300 Blackout was purpose-built to perform out of short barrels, and at 10.5 inches this pistol sits right in the sweet spot for the cartridge. Supersonic loads hit hard and cycle reliably, and if you run a suppressor, the threaded barrel and subsonic ammo options make this a genuinely quiet package. The 1:8 twist handles the full range of .300 BLK bullet weights, from light fast loads to heavy subsonic projectiles, without issue. It uses standard AR-15 magazines, so the 30-round PMAG it ships with is just the starting point.

Frequently Asked Questions
Does the H&R Commando come with a magazine?
Yes, it ships with one 30-round PMAG. Since it uses standard AR-15 .300 Blackout magazines, you can pick up any compatible 5.56/300 BLK AR magazine to add to your supply. The lower is specifically marked for .300 Blackout so there's no guesswork.
Is the barrel threaded for a suppressor?
It is. The 10.5" barrel is threaded 5/8×24, which is the standard thread pitch for .300 Blackout suppressors and most popular muzzle devices in that caliber. The factory A2-style flash hider can be swapped out whenever you're ready.
Can the carry handle be removed to mount an optic?
The A2 carry handle on the H&R Commando is a fixed, integrated feature of the upper receiver, not a removable flat-top accessory. If you want to run a red dot or scope, you can mount an optic directly to the carry handle using a handle-mount adapter, or use the built-in iron sights as-is. The carry handle design is part of the 733-style aesthetic.
How does .300 Blackout perform out of a 10.5" barrel?
This is actually the ideal barrel length range for the cartridge. Unlike 5.56, which loses meaningful velocity in short barrels, .300 Blackout was engineered to reach peak performance in barrels between 9 and 16 inches. Supersonic loads cycle reliably and hit hard, and the 10.5" length burns subsonic powder efficiently for suppressed use.
What magazines does the H&R Commando use?
.300 AAC Blackout uses the same standard AR-15 lower receiver dimensions, so the Commando accepts any AR-compatible .300 Blackout magazine. The included 30-round PMAG is a great starting point, and most major AR mag brands work fine. Just stick to magazines labeled for .300 Blackout or 5.56 AR-pattern platforms.
Is the 733-style design just cosmetic, or does it affect the build quality?
The retro styling runs deeper than just aesthetics. The forged 7075-T6 receivers, Parkerized finish, Carpenter 158 steel bolt, and mil-spec trigger group are all substantive specs, not corners cut to hit a price point. The 733 platform was a real military design, and H&R built this version to reflect that with current production standards.
