Clean, Streamlined Look; Made To Mil-Spec Standards
One-piece rails cut to true, MIL-STD 1913 Picatinny spec match the look and feel of your standard, A4 flattop while adding ½" of height for proper cheek weld with optics and tactical sights. Streamlined design encloses the receiver rail for a “built-in” appearance and eliminates protruding hardware that can snag on brush, slings, and clothing. Nylon-tipped, Allen screws, tapped through the top, deliver downward pressure between the receiver rail slots for exceptional holding power. Precision machined from strong, yet lightweight 6061-T651 billet aluminum, then hardcoat anodized with a tough, Teflon-impregnated finish to Mil-A-8625 for extra strength and superior wear resistance. Scout Rail provides 3½" of valuable rail space over M4-style handguards for mounting tactical optics farther forward. Standard model provides maximum flexibility in positioning optics. BUIS Scout Rail - Chopped, tail section allows attachment of a flip-up, rear sight to the back of your existing flattop rail, so it regulates properly with standard issue front sights.
