SI collar adjustable works
Reviewed on April 30, 2026Verified with Build

Strike Industries collar adjustable gas block works as advertised. Clamp-on design means no dimple required on the barrel. Detent positions are crisp for tuning gas. Solid budget adjustable gas block option for builders.

SI collar adjustable gas tune
Reviewed on April 9, 2026Verified with Build

Strike Industries collar adjustable gas block tunes easily through detent positions. Clamp on means no dimple required. Set the gas right and the rifle cycles smoothly with suppressor on or off. Best adjustable block at this price.

SI collar adjustable gas block
Reviewed on April 4, 2026Verified with Build

Strike Industries collar adjustable gas block lets me tune gas pressure without removing the handguard. Clamp on design - no dimple required. Multiple detent positions. Cleaner installation than a set-screw adjustable.

SI collar block
Reviewed on January 31, 2026Verified with Build

collar style means no roll pin to drill out if you ever change barrels. tuned this in about 15 min on a 14.5 mid length, gas adjustment is positive and the detent holds settings well. SI quality is reliable for the price
