Strike Industries Oppressor Universal 3-Lug QD Base Set Features The Strike Industries Oppressor Universal 3-Lug QD Base Set gives owners of the SI Oppressor Universal suppressor the ability to mount an additional dedicated base on a second compatible barrel. This means one suppressor body can be quickly detached from one firearm and attached to another without needing a second full suppressor saving both time and money for owners running multiple threaded barrels. Made from S45C steel the base is built to handle the repeated mounting and dismounting cycles that come with swapping a suppressor between firearms. Because this 3-lug quick detach base is a unique fitment made specifically for the Oppressor Universal it integrates seamlessly with the existing suppressor body. The set ships with all the hardware needed for a proper installation including a 1/2 inch concentric shim washer along with both 1/2 inch and 5/8 inch crush washers to accommodate different thread pitches. This hardware ensures the base indexes correctly and locks up tight against the muzzle device for consistent repeatable suppressor alignment. Finished in Black with silver accents the base matches the look of the original Oppressor Universal body. For owners who want to extend the versatility of their Oppressor Universal suppressor across multiple rifles or pistols this base set is a cost-effective way to do it.
