Description
The Samson SXT 15-inch handguard gives you a serious stretch of forend to work with while keeping your barrel free-floated for better consistency downrange. It's machined from 6061-T6 aluminum and finished in a Type III hardcoat anodizing, so it holds up to knocks, heat, and years of range use without looking beat up. At 15 inches, you've got room to run your hand well forward, mount a light and pressure switch, add a bipod, and still leave space for a vertical grip.
What Sets the SXT Series Apart
Samson redesigned this rail from the older SXS setup, and the improvements show. You get a 7-sided M-LOK layout that opens up mounting angles all the way around, a sleek chamfered leading edge that won't snag on gear or your bag, and an ambidextrous integrated QD sling point so lefties and righties both get a clean attachment. It also ships with a 2-inch M-LOK rail section to get you started on accessory mounting right out of the gate.
Installing the Samson SXT Handguard
This is where the SXT really earns its keep. Instead of fussing with bias blocks and knurling like the old design, the SXT uses a simple clamping system with two cross bolts that lock into the included barrel nut. It's a fast, straightforward install that most folks can handle at the bench with basic tools. The kit comes with the barrel nut and a hex wrench, so you're not scrambling for parts partway through the job.
Made in New Hampshire, the SXT hits a sweet spot for anyone building or upgrading an AR-15 and wanting a full-length free-float rail that's tough, light, and genuinely easy to bolt on. It's a no-drama upgrade that looks sharp and works hard.

Frequently Asked Questions
How does the Samson SXT handguard attach to the rifle?
The SXT uses a clamping system with two cross bolts that lock into the included barrel nut. This design skips the old bias block and knurling method, making installation quick and repeatable. Most builders can get it mounted at the bench with basic hand tools.
Is the barrel nut included with the SXT 15-inch handguard?
Yes, Samson includes the barrel nut, a hex wrench, and a barrel nut wrench in the box. That means you have the core tools and hardware needed to complete the install without extra purchases. You'll still want a proper vise and upper receiver block for a solid setup.
Does the Samson SXT free-float the barrel?
It does. The SXT is a free-float design, meaning the handguard mounts only at the receiver and does not touch the barrel. That helps keep your accessories from putting pressure on the barrel, which supports more consistent shooting.
What accessories can I mount on the SXT M-LOK handguard?
The 7-sided M-LOK layout lets you attach lights, lasers, bipods, hand stops, vertical grips, and pressure switches using standard M-LOK hardware. It also has an integrated QD sling point on both sides for sling attachment. A 2-inch M-LOK rail section comes included to get you started.
