Description
I was at the range last week, zeroing a new optic on a .308 AR platform, and the guy next to me was wrestling with a heavy, over-gassed rifle that was beating him up. It reminded me why I appreciate a well-sorted, no-nonsense rifle like the Radical Firearms RF-10. You don’t always need a $2,500 custom build to get reliable, hard-hitting performance. Sometimes, you just need a tool that works.
So, what is the Radical Firearms RF-10 308 Win, 18″ Barrel, 6 Pos MFT Stock, Black, 20rd? It’s a direct-impingement AR-10 platform rifle chambered in .308 Winchester/7.62x51mm NATO. It features an 18-inch, button-rifled, chrome-moly barrel with a 1:10 twist, a 6-position MFT minimalist stock, and ships with a 20-round PMAG. At its core, it’s a purpose-built, value-oriented rifle designed for hunting, target shooting, and general-purpose use where the .308’s power is needed. Weighing in at approximately 8.5 lbs unloaded, it strikes a solid balance between heft for recoil management and portability for field use.
Let’s talk about the barrel. That 18-inch length is a real sweet spot for the .308. You get nearly all the velocity of a 20-inch barrel but with better maneuverability, especially if you’re moving through a deer blind or navigating a wooded property. The 1:10 twist rate is a classic for the caliber, stabilizing a wide range of bullet weights from 150-grain soft points for deer to heavier 175-grain match rounds. I’ve put a few hundred rounds of mixed brass through this setup, and it’s consistently delivered minute-of-angle accuracy with good factory ammo—no gunsmithing required to get it running right out of the box.
The build uses a mil-spec compatible design, which is a huge plus. That means the 6-position MFT Battlelink stock is a standard tube fit, and the rifle accepts most common AR-10 pattern components. The handguard is a slim, free-float M-LOK system, giving you plenty of real estate for lights, grips, or bipods. I paired mine with a Magpul bipod and a Vortex scope on a standard Picatinny mount, and everything fit perfectly. The rifle comes with a standard A2 flash hider, which does the job, though many shooters eventually swap it for a muzzle brake or compensator to further tame the .308’s push.
Here’s the thing—at $890.73, you’re getting a complete, functional .308 AR. You aren’t paying for a fancy rollmark or boutique-level finishing. You’re paying for a solid foundation. The controls are all where you expect them, the bolt carrier group is properly staked, and the fire control group provides a clean, predictable break. It’s a rifle that invites you to shoot it, learn its character, and upgrade parts as you see fit, not one that demands immediate modifications just to function reliably.

Pros & Cons
The pros are clear: significant cost savings for a complete rifle, a practical 18-inch barrel, full compatibility with the huge AR-10/LR-308 aftermarket, and reliable performance with common PMAGs. It’s drop-in ready for optics and accessories. The cons? Fit and finish are utilitarian—don’t expect laser-engraved logos or a mirror-polished chamber. The trigger is a basic mil-spec unit, which is functional but often the first part shooters replace. Recoil is manageable but present, as with any .308 of this weight.
Who is this rifle for? It’s for the Missouri hunter who wants a versatile, semi-auto platform for whitetail or hog. It’s for the shooter who wants to step into the world of .308 ARs without a massive initial investment. It’s also a great candidate for a “build on a budget” project gun, where you can gradually upgrade the trigger, muzzle device, and optic over time. This rifle is available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases.
Frequently Asked Questions
Q: Is this rifle compatible with all AR-10 parts?
A: It follows the DPMS-pattern LR-308 specifications, which is the most common standard. Upper receivers, handguards, bolts, and triggers designed for DPMS-pattern .308 rifles will be compatible. Always double-check compatibility for specific parts, but you’re working with a widely supported platform.
Q: What’s the effective range with the 18-inch barrel?
A: With quality ammunition, the 18-inch barrel is more than capable of making consistent hits on man-sized targets out to 800 yards. For hunting, it’s perfectly effective at any ethical range you’d engage game, with plenty of retained energy. The 20-round magazine capacity gives you plenty for a range session or a follow-up shot in the field.
Q: Can I use 7.62x51mm NATO surplus ammo in this rifle?
A: Yes, the chamber is designed to safely fire both .308 Winchester and 7.62x51mm NATO. As always, start with a thorough function check when switching ammo types or brands to ensure reliable feeding and ejection.
