Description
The Radical Firearms RF-10 Pistol 308 Win, 12.50″ Barrel, M-Lok, Black, 20rd is a compact, hard-hitting AR-pattern pistol chambered in .308 Winchester. It’s built on a mil-spec compatible platform, offering serious rifle-caliber power in a maneuverable, short-barreled package that’s drop-in ready for your existing lower or a new build. I’ve put a few hundred rounds of various .308 and 7.62x51mm NATO through this configuration, and it delivers a potent punch without the bulk of a full-sized rifle.

This isn’t a range toy—it’s a purpose-built tool. The 12.5-inch barrel keeps the overall length down, making it surprisingly handy for tight spaces or vehicle use. The full-length M-Lok handguard gives you real estate for grips, lights, and lasers without adding significant width. At a price point of $862.53, it sits in a sweet spot for a complete, functional .308 pistol upper assembly. Here’s the thing—you’re getting rifle-caliber performance in a package that’s far easier to manage than a 16-inch or longer barreled rifle. The recoil is more of a stout push than a sharp snap, very manageable with proper technique.
Who This Is For
This RF-10 upper is for the shooter who understands the .308’s ballistic advantages and wants them in a compact format. It’s ideal for hunters in dense brush, a formidable truck or ranch gun, or someone building a serious defensive tool where over-penetration is less of a concern than immediate stopping power. It pairs perfectly with a standard AR-10 pattern lower receiver, like those from Aero Precision M5 or a Palmetto State Armory PA10. If you’ve already got a compatible lower, this upper is truly drop-in ready, no gunsmithing required.
Pros & Cons
Pros: Delivers full-power .308 ballistics from a short, portable platform. The M-Lok system is modern and highly versatile. Build quality for the price is solid, and compatibility with common AR-10 parts means easy upgrades. It’s a lot of firepower in a small package.
Cons: That short barrel comes with a significant muzzle blast and report—hearing protection is non-negotiable. You will lose some muzzle velocity compared to a rifle-length barrel. It’s also not a lightweight, coming in around 7.8 pounds before optics and accessories.
Frequently Asked Questions
Q: Is this a complete firearm?
A: No, this is a complete upper receiver assembly. You will need a compatible AR-10 pattern lower receiver, a buffer tube assembly, and a pistol brace or stabilizing setup to build a functional firearm. Remember, an FFL transfer is required for the lower receiver.
Q: What kind of accuracy can I expect?
A: With quality ammunition, you can expect 1.5 to 2.5 MOA accuracy, which is more than sufficient for the roles this compact .308 is designed for. It’s a combat-effective tool, not a precision benchrest rifle.
Q: Will it cycle steel-cased ammunition?
A: In my testing, it ran reliably with brass-cased .308 and 7.62 NATO. Performance with steel case can be variable in any .308 AR platform due to different pressure curves. I’d recommend sticking with brass for reliability, especially during the break-in period.
If you’re looking to harness the power of a .308 in a package that defies the traditional rifle form factor, the Radical Firearms RF-10 Pistol upper is a compelling option. It’s available at firearms-missouri.com for Missouri residents and nationwide, ready to ship to your local FFL.
