ENHANCED GAS RINGS Fights Carbon Fouling & Helps Maintain Reliability
SPIKE’S TACTICAL AR-15/M16
JP’s one-piece gas ring combines a superb gas seal with a very low-friction relationship between rings and bolt carrier. Decreased resistance between rings and carrier results in a direct increase in the rifle’s reliability. In addition, the ring’s precision-ground surface is contoured to use the cycling action itself to scrape the walls of the carrier, so it combats carbon buildup with every shot. Ideal for use on the JP EnhancedBolt™. JPGR-223 fits bolts on rifles chambered in .223/5.56mm NATO. JPGR-308 fits rifles chambered in .308 Win/7.62mm NATO. a b #452-000-170EN JPGR-223 Gas Rings, 2E8G70 ���������������� $ 9.99 #452-000-169EN JPGR-308 Gas Rings, 2E8F70 ���������������� 9.99

Integral gas block and folding front sight replicates the appearance of the classic factory front sight tower, yet folds neatly out of the way when it’s not needed. Eliminates need to purchase a railed gas block and a separate rail-mount folding sight. Deploys and locks securely in place as quickly as any flip-up combat sight. To fold, press straight down on the top of the diagonal rear support to release the lock and pull back on the sight tower. Standard A2-type sight post, so it works with any factory-height rear sight. Easy to install; dual clamping rings fit standard .750" diameter barrels, and hex-head bolts (hex wrench included) provide plenty of clamping force to make sure the sight doesn’t shift and change point of aim. Steel base/gas block provides exceptional resistance to erosion by hot gases. Includes bayonet lug, and rear clamping ring drilled to accept sling swivel pin. Aluminum tower minimizes weight without sacrificing strength. a b SPECS: Steel and aluminum, matte black finish. Fits barrels that are .750" O.D. at the gas port. #100-003-742EN #41-BL Silhouette Folding Front Sight, 3A147M50 �������������������������������������$ 154.99

LOW-PROFILE GAS BLOCK Lightweight, Minimal Profile To Fit Under Tactical Handguards & Free-Float Tubes Low-profile gas block fits under just about any extended handguard while ensuring proper gas flow to keep your rifle cycling reliably. Precision machined from lightweight, yet tough, 6061 T6 aluminum, so it won’t add unwanted forward weight. Slide over the barrel and anchor in position by tightening the three, flush-mounted steel hex screws on the underside to ensure it won’t shift even under sustained full-auto fire.
