Other Accessories
Why do I need Accessories?
Whether you’re looking to build or modify your 80% AR15 build kit or 80% pistol build, no build is complete without making it truly yours.
We carry the best 80% lower receivers in the industry and to go along with our premium lowers, we also carry the premium products you need to make your gun fit the role you need it to fill.
What accessories do I need?
A new sight or optic could help you reach new distances you once thought were impossible. You could also upgrade your Glock or AR with a new trigger to help you shoot faster, or more accurately. If you’re in the state of California you may be looking at some accessories to make your rifle CA compliant. We have everything you need and in between to get the job done!
