Threads out of tolerance.

Written on Nov 16, 2022

I ordered this for my bear creek arms 450BM. The brake threaded on fine by hand but when I tried to tighten it onto the crush washer to time it it stripped off the tops of the threads on my barrel. The minor diameter tolerance for a 5/8-32 2A thread is 15.011mm to 15.215mm and the brake measured 15.51mm. Having a defective product is frustrating enough but having it also damage my barrel is unacceptable.
