Wouldn’t it be cool if you could adjust the bolt cycling energy on your AR-platform rifle? Turn down the cycling rate for slow fire at the bench or varmint hunting. Crank up the energy for 3-Gun matches and rapid-fire disciplines. This IS possible with a handy accessory that fits on your barrel. Wilson Combat offers an Adjustable Lo-Profile AR Gas Block for direct gas impingement AR-type rifles. Wilson Combat’s adjustable gas block replaces a standard AR gas block and allows you to tune your AR’s gas system for smoother cycling and enhanced reliability. Wilson Combat explains: “Adjusting your rifle’s gas port will lower or increase your bolt’’s cyclic rate. This tailors your rifle’s performance to your unique needs.”

A simple adjustment of the hex screw at the front of the block modulates the gas volume allowing you to tune your rifle’s function to your favorite loads. This is very handy when shooting non-standard AR calibers, unusual hand-loads, or suppressed rifles. Adjustable Gas Block systems are sold as complete kits starting at $61.07. Wilson Combat offers two diameters (.750″, .875″) so you can select the right dimensions for your rifle configuration and barrel diameter. The blocks are Chromoly steel with a black Melonited finish.
