The Samson DPMS G2 SXT is a 15-inch free-floating handguard built for DPMS G2-pattern .308 and 7.62 AR-10 rifles. It's aimed at shooters who want a longer sight radius, more real estate for accessories, and the accuracy benefit of keeping the barrel free of contact. At 14 ounces with a 1.40-inch inside diameter and a 1.80-inch outside diameter, it stays slim enough to handle well while clearing most heavier .308 profiles. One note up front: this rail will not fit .308 rifles that use a fixed front sight. If you're building or upgrading a DPMS G2 platform, this is a direct-fit option from a maker known for precision handguards.
Construction is 6061-T6 aluminum finished with MIL-A-8625 Type 3 Class 2 hardcoat anodizing, which holds up to abrasion and corrosion in field use. The M-LOK interface runs the length of the rail and accepts M-LOK hardware directly, so you can add light mounts, bipod adapters, sling points, and vertical grips where you actually need them rather than carrying weight you don't use. Installation runs through a cross-bolt clamping system that locks onto the proprietary DPMS G2 barrel nut, which Samson includes along with a hex wrench. That clamping setup keeps the rail indexed and rigid without proprietary tools or a vise full of fixtures. The free-floating design means the handguard carries on the barrel nut alone, so nothing touches the barrel to disturb your zero.
This rail suits designated marksman builds, precision hunting rigs, and any DPMS G2 .308 that needs a modular front end for optics-forward setups, night vision, and stabilized shooting. The 15-inch length gives you room to run a bipod well out toward the muzzle while still leaving space for a hand stop or barricade support closer in. Pair it with a quality bipod or a forward vertical foregrip to round out the build. Confirm your rifle uses the DPMS G2 barrel nut pattern and lacks a fixed front sight before ordering, and it'll bolt up clean.
No. The SXT is cut for the DPMS G2 (Gen 2) barrel nut pattern specifically. It will not fit other .308 receiver patterns, and it will not work on rifles equipped with a fixed front sight. Confirm your rifle is a DPMS G2 platform before ordering.
A free-floating handguard mounts only to the barrel nut and never contacts the barrel itself. That keeps sling tension, bipod loading, and hand pressure from flexing the barrel, which helps the rifle hold a consistent zero shot to shot.
Samson ships the rail with a hex wrench and the proprietary DPMS G2 barrel nut required to mount it. Installation uses a cross-bolt clamping system that indexes onto that barrel nut for a rigid, repeatable fit.
Yes. The full-length M-LOK interface accepts M-LOK hardware directly along the rail, so you can add bipod adapters, light mounts, sling points, and hand stops at the positions you need without extra rail sections.
Per manufacturer specifications, the rail weighs 14 ounces. The 6061-T6 aluminum construction and 1.80-inch outside diameter keep it slim and light for a 15-inch .308 handguard.
