Troy Alpha Rail Strx-Al1-13Bt-01 13" - Black

The Troy Alpha Rail is a 13-inch free-float handguard built for shooters who want a lightweight, proven platform for their AR-15. This machined aluminum handguard uses Troy's distinctive barrel-nut and rotary-locking system to align the top rail perfectly with your receiver—no guesswork, no wobble. The handguard slides onto your barrel and gas tube at an offset angle until the notched barrel nut locks into an internal grooved channel, then two hex-head screws secure it down. A built-in stop prevents over-tightening, so you get a consistent, reliable fit every time.

The Alpha's minimalist design centers on a single top Picatinny rail for your optic, paired with deep horizontal grooves that give you a solid, no-slip grip even in adverse conditions. Strategic vent holes cut through the handguard to let barrel heat escape and shed unnecessary weight—a smart move for hunters and range shooters who value mobility without sacrificing rigidity. The included three bolt-on rails let you mount accessories (lights, grips, bipods, barricade stops) precisely where you want them, and white alpha-numeric designators stamped into the cross-slots make it easy to dial in repeatable positions for your setup.

If you're running a standard factory AR-15 or M16 barrel nut, the Troy Alpha is a direct fit. It's the kind of no-nonsense handguard that works equally well on a hunting rifle, 3-gun competition gun, or a precision range build—proven design that's been trusted by serious shooters for years.
