Ties Together Receiver & Free-Float Tubes For Strength; Mounts Optics & Sights "SPR" Style
Precision machined MIL-STD 1913 Picatinny rail ties the upper receiver to the forearm for extra rigidity, plus gives you the “SPR” look in a .308 package. Lets you mount optics and same-plane tactical sights for maximum versatility and accuracy. Connects directly to the forearm. Numbered cross-slots allow easy return to zero when sights are removed then re-installed and give plenty of flexibility in ring spacing for different-length scope tubes, sights, or co-witness capability. Short has a 17" long rail with 40 cross slots. Fits ArmaLite® AR-10® and Knight’s Armament SR-25 uppers with free-float forends. Includes a single slot rail to mount a same-plane front sight. Full Length has a single 19" long rail with 46 cross slots. Fits ArmaLite® AR-10®, Knight’s Armament SR-25, and old style DPMS upper receivers with free-float forend.
