Strike Industries Oppressor Universal Blast Shield - Aluminum Black$109.95
Availability: In Stock
The Strike Industries Oppressor Universal 3-Lug QD base set is your ticket to running one suppressor body across multiple rifles without buying separate cans for each caliber or platform. If you already own an SI Oppressor Universal suppressor, this additional quick-detach base lets you install it on a second barrel, saving you serious money while keeping your setup flexible. It's a no-fuss way to maximize your investment in a quality modular suppressor.
The base itself is machined from S45C steel and uses Strike's proprietary 3-lug quick-detach interface—meaning it only works with the SI Oppressor Universal body, not the original Oppressor or Oppressor Lite models. The kit ships with everything you need to get it running: the QD base, a 1/2" concentric shim washer, AR-style crush washers for both .223/5.56/9mm (1/2") and .308/7.62 (5/8") applications, and clear installation documentation. That thoroughness means no hunting for the right hardware when you're ready to swap barrels.
Compatibility spans common rifle and pistol calibers—.223/5.56, .308/7.62, and 9mm—so whether you're threading it onto an AR upper, a bolt gun, or a pistol barrel, you've got coverage. Just confirm your barrel is 1/2" or 5/8" threaded and that any muzzle device or brake you're using maxes out at 25mm diameter; the overall diameter of the assembled Oppressor U is 41mm. This is the smart play for shooters who want one suppressor doing double or triple duty across their battery.

No. This 3-lug QD base is proprietary to the SI Oppressor Universal body only. It is not compatible with the original Oppressor or Oppressor Lite models.
The base accommodates 1/2" and 5/8" threaded barrels. The kit includes crush washers sized for both, so you're covered whether you're running it on a .223/5.56/9mm barrel (1/2") or a .308/7.62 barrel (5/8").
Yes—that's the entire purpose of this base set. Once you install a base on a second barrel, you can quickly detach the Oppressor Universal body from one barrel and attach it to the other using the QD system, letting you move one suppressor between firearms.
The base and Oppressor Universal body are rated for .223/5.56, .308/7.62, and 9mm.
