The Strike Industries Universal Oppressor is a blast shield that can work with almost all muzzle devices. Generally, when you install a muzzle brake, you get recoil and muzzle rise reduction, but a very aggressive and concussive shooting experience. Similarly, a blast shield on its own can redirect muzzle flash and concussive noise away from the shooter but doesn't do much for compensating recoil and muzzle rise.

The Strike Industries Oppressor offers a no-compromise solution, as it can be mounted over a muzzle brake and redirect the aggressive muzzle blast.

Allows You To Install The SI Oppressor On Multiple Firearms

It attaches to the barrel using a 3-Lug QD Base, which is installed on the barrel before a muzzle brake. Installing the 3-Lug QD Base on your rifles allows you to place the SI Oppressor from one firearm to the other easily. It is very easy to install and comes with all the necessary hardware to install it on an individual barrel.

Made To Last

The Strike Industries Oppressor Universal 3-Lug QD Base Set is compatible with 5.56/.223, 7.62/.308, and 9mm caliber barrels. It is made from S45C steel and has a Parkerized finish for durability.
