Product Description The Seekins Precision Low Profile Adjustable Gas Block is designed to help you fine-tune your rifle&';s gas system for smoother cycling and more consistent operation. By regulating the amount of gas used to cycle the action, you can tune function for specific loads and support the use of low-mass bolt carriers, buffers, and springs to help reduce felt recoil. Its low-profile design measures approximately 1.37 in tall and 0.94 in wide to fit under most handguards, while the Black Melonite coating helps reduce wear and corrosion during extended firing sessions. Note: This model does not include a gas tube roll pin.
