The JP Enterprises JP Adj Gas Block Ss .750 Blk No Rail delivers a compact, under-rail adjustable gas system designed for AR-15 rifles with a .750 inside diameter. Crafted from 416 stainless steel with a durable black finish, this lightweight gas block weighs 2.25 oz and measures approximately 1.28 inches in length, 1.40 inches overall height, 0.78 inches over bore, and 0.89 inches in width, providing full coverage around the gas port for a superior seal and improved heat dissipation. Its true clamp-on design uses four positive clamping screws for secure, repeatable mounting, while easy-to-access side gas adjustment ensures reliable tuning in the field or on the range. The JPGS-5B includes a locking adjustment feature with an integral brass set screw that can be tensioned against the adjustment screw to prevent migration after setup.
