Radical Firearms RF-15: What You Get in the Base Rifle

The Radical Firearms RF-15 is a mil-spec AR-15 pattern rifle built on a forged 7075-T6 aluminum lower and upper receiver. It ships with a cold hammer-forged barrel, a mid-length or carbine-length gas system depending on barrel length, a 15-inch M-LOK free-float handguard, and a B5 Systems SOPMOD stock on most configurations. The trigger is a standard mil-spec unit—functional, not exceptional. The cold hammer-forged barrel is the notable spec for the price; most budget AR-15s use button-rifled barrels, and CHF barrels offer better longevity under sustained fire. The RF-15 ships in multiple barrel lengths from 16-inch rifle to 10.5-inch pistol.

Radical Firearms vs DPMS: Two Budget AR Brands Compared

Radical Firearms and DPMS occupy similar price territory in the AR-15 market. DPMS has a longer track record and broader brand recognition but has been through corporate ownership changes (Remington, now part of the bankruptcy aftermath). Radical Firearms is independently owned and in active production with a current lineup. Both use mil-spec components with forged receivers. The key difference: Radical Firearms’ standard CHF barrels versus DPMS’s button-rifled barrels on comparable-priced rifles. For a buyer choosing between the two today, Radical’s current production status and the CHF barrel spec make it the stronger choice at similar price points.

Radical Firearms Pistol Configurations: .300 Blackout and 7.62x39

Radical Firearms produces AR-pistol configurations in .300 Blackout and 7.62x39 that are popular suppressor hosts and home defense platforms. The 7.62x39 RF-15 pistol uses a modified bolt carrier group and a barrel cut to accept the wider x39 cartridge, with a 10.5-inch barrel in the most common configuration. The .300 Blackout version accepts standard .223/5.56 AR magazines with a follower swap and offers true sub-caliber suppressor performance with subsonic 220-grain loads. Both pistol variants are short, maneuverable, and compatible with most AR-15 accessories. Since the NFA tax stamp was eliminated January 1, 2026, adding a stock to these pistols or running them suppressed has never been more practical.

Radical Firearms Uppers: Building on a Budget

Radical Firearms sells complete upper assemblies—with bolt carrier group and charging handle—separately from complete rifles, which is useful for builders who already have a lower and want to add a caliber conversion or replace a worn barrel. Their uppers use the same CHF barrels and free-float M-LOK handguards as their complete rifles. A Radical upper on a quality mil-spec lower is a common budget build that delivers a solid shooting package. The BCG included with Radical uppers is phosphate-coated mil-spec and functions reliably; upgrading to a nickel-boron or NiB-X BCG later is an easy quality improvement for those who want it.

Who Should Buy Radical Firearms?

Radical Firearms is the right choice for a first-time AR buyer who wants a complete, functional rifle without paying mid-tier prices; for a shooter building a budget safe queen in a caliber they don’t shoot often; or for someone who wants a dedicated .300 Blackout or 7.62x39 upper without committing significant money. If you plan to shoot 5,000+ rounds per year competitively or use your rifle in an extreme-conditions role, stepping up to a Daniel Defense, BCM, or Noveske is worthwhile. For recreational shooting, hunting, and home defense where reliability under normal conditions is the standard, the RF-15 delivers what it promises at its price point.
