Seekins Precision Select LR-308 Adjustable Gas Block .750" Steel Black Melonite

The Seekins Precision Select LR-308 Adjustable Gas Block is a steel gas block for AR-10 platform rifles chambered in .308 Winchester. It is designed to let the operator tune gas flow for different loads and for suppressed or unsuppressed firing, which helps when a suppressor, dirty conditions, or a change in ammunition affects gas settings.

The block offers 30 adjustment settings, allowing fine tuning to a specific suppressor or ammunition type. Once set, a simple throw lever permits on-the-fly changes without tools. The black Melonite finish is applied to the steel body.

It fits the .750 inch gas tube found on AR-10 and LR-308 rifles.
