Radical Firearms RF-15 .300 Blackout 8.5″ Pistol 30rd

Description

The Radical Firearms RF-15 .300 Blackout 8.5″ Pistol 30rd is a compact AR-style pistol built for shooters who want a short-barrel platform without sacrificing accuracy or accessory capability. Chambered in .300 AAC Blackout with an 8.5-inch HBAR barrel, this pistol delivers reliable cycling for both supersonic and subsonic loads. The forged 7075 T6 upper and lower receivers with Type III hard-coat anodizing ensure the frame holds up to hard use, while the 7-inch free-float RPR M-LOK handguard gives you a full-length rail for lights, lasers, or grips without adding bulk. At $632.00, it’s a solid entry point for a dedicated .300 Blackout pistol that’s ready to run out of the box.

Key Features

• 8.5″ HBAR Barrel with 1:8 Twist — The heavy-profile barrel stabilizes both 110-grain supersonic and 220-grain subsonic loads, giving you consistent accuracy across the full .300 Blackout spectrum. The 1:8 twist rate is the sweet spot for this caliber, and the 4140 Chrome Moly Vanadium steel holds up to sustained fire.
• Forged 7075 T6 Receivers with Type III Anodizing — These receivers are heat-treated and hard-coated to resist wear, corrosion, and impact. Forged construction means the metal grain is aligned for strength — not cast or billet shortcuts. This matters when you’re running a short-barrel pistol hard.
• 7″ Free-Float RPR M-LOK Handguard — The free-float design keeps barrel harmonics consistent, improving accuracy. The M-LOK slots let you mount accessories anywhere along the rail, and the full-length top rail gives you plenty of real estate for optics or backup sights.
• MIL-STD Controls — Safety selector, magazine release, and bolt catch are standard AR-15 pattern, so you can swap parts or upgrade triggers without proprietary headaches. Everything is familiar to anyone who’s run an AR platform.
• Compact Form Factor for Short-Barrel Roles — At 8.5 inches, this barrel keeps the overall length short enough for vehicle carry, home defense, or suppressed use. The pistol configuration avoids NFA restrictions while giving you a real rifle cartridge in a small package.

Who It’s For

This pistol is built for shooters who want a dedicated .300 Blackout platform without paying a premium. It’s ideal for home defense where you want the terminal performance of a rifle round in a compact package, or for hunters who need a suppressor-friendly pistol for subsonic loads. The RF-15 also appeals to builders who want a complete upper and lower ready to customize — the MIL-STD controls and M-LOK handguard make upgrades straightforward.

Pros & Cons

• Pro: Price point — at $632, it’s one of the most affordable complete .300 Blackout pistols from a known manufacturer.
• Pro: Barrel quality — the 4140 Chrome Moly Vanadium with 1:8 twist handles both supersonic and subsonic loads accurately.
• Pro: Handguard — the 7-inch free-float RPR M-LOK offers plenty of accessory space without adding weight.
• Con: No iron sights or optic included — you’ll need to budget for sights or a red dot. The pistol comes with a bare rail.
• Con: The 8.5-inch barrel is on the short side for maximum velocity with supersonic loads — expect around 2,150 fps with 110-grain ammo instead of the 2,400 fps you’d get from a 16-inch barrel.

Comparison: RF-15 vs. Zev Technologies & Lone Wolf Distributors

Feature	Radical Firearms RF-15	Zev Technologies OZ9C	Lone Wolf Distributors DLC-9
Caliber	.300 Blackout	9mm Luger	9mm Luger
Barrel Length	8.5″	4.5″	4.6″
Frame Material	Forged 7075 T6 Aluminum	Billet 7075 T6 Aluminum	Polymer with steel insert
Handguard	7″ Free-Float M-LOK	Integrated optic plate	Picatinny rail
MSRP	$632	$1,200+	$450

The RF-15 offers a rifle-caliber option in a pistol format, while the Zev and Lone Wolf are 9mm pistols. If you want the ballistic advantage of .300 Blackout in a compact platform, the Radical Firearms pistol is the clear choice. The Zev is higher-end for competition shooting, and the Lone Wolf is budget-friendly for 9mm, but neither matches the RF-15’s suppressor-ready capability.

FAQ

Does this pistol come with a brace or buffer tube?

Yes, the RF-15 includes a standard carbine buffer tube and a pistol stabilizing brace. The brace is adjustable for length of pull.

What magazines does it use?

It uses standard AR-15 .300 Blackout magazines. The included magazine is a 30-round polymer unit. Note that .300 Blackout magazines are identical to 5.56 magazines in external dimensions, so they work with any standard AR lower.

Can I run subsonic ammunition without a suppressor?

Yes, the 1:8 twist stabilizes subsonic rounds, but you’ll lose some reliability without a suppressor due to reduced back pressure. For best function with subs, use a suppressor or consider a heavier buffer. Per Radical Firearms, the pistol is designed for both supersonic and subsonic loads with proper tuning.

Is the barrel threaded?

Yes, the barrel is threaded 5/8×24 TPI for suppressors or muzzle devices. A standard A2-style flash hider is included.

What is the warranty?

Radical Firearms offers a limited lifetime warranty on the receiver and a one-year warranty on the barrel and components. Contact their customer service for specific coverage details.
