Gas blocks

DoubleStar has added three gas blocks to its AR-15 product line. The trio includes a two-piece two-rail, a one-piece four-rail and a low-profile block. The two-piece and four-piece blocks are made of standard 6061 T6 aircraft-grade aluminium with a hard coat anodized finish for a lighter weight. Each has 1913 Picatinny rail systems to accept accessory attachments.

The four-rail system is securely held in place with three sets of screws, rather than the typical two. The screw sets -- two on the bottom and one on top -- ensure a perfect gas seal. The four-piece system is made to fit .75-inch diameter barrels. The two-piece gas block is easily and securely installed with four socket head machine screws. It is available for a .750-inch diameter barrel or a .625-inch diameter A1 barrel. DoubleStar's low-profile gas block is made from 1018 steel and is Mil-Spec parkerized, yet maintains a light weight. Designed for shooters who always use a scope, the low-profile gas block replaces the front sight.
