Next Evolution In Concussion Reduction for the AR-15

The Strike Industries Oppressor Blast Shield is the next evolution in concussion reduction for the AR-15 platform. Effective for reducing side concussion, this device is compatible with a number of Strike Industries muzzle devices. It is designed with computer-aided flow dynamics, that provide a no-compromise solution for redirecting the overpressure produced by aggressive brakes and compensators.

This device uses a proprietary quick detach mounting system that can be easily installed before transitioning to prone shooting positions, or for indoor use.

Advanced Internal Geometry

Precision machined from 1045 carbon steel, the Oppressor has a hard black nitride finish to ensure longevity.   It also features advanced internal geometry that actively draws the gasses out and thrusts the gasses forward through vents to accomplish linear braking in order to retain more braking efficiency.

The SI Oppressor Blast Shield is compatible with the SI muzzle devices to include: Venom-FH, Checkmate Comp, King Comp, MK-9 Comp, J-Comp Gen2, Sierra Comp, and Triple Crown Comp.
