Seamless change over by docwong, Verified Owner, December 9, 2025

Going to try a different muzzle brake just for the heck of it. The one I have now on my is threaded 1/2 x 32 pitch. I used the precision armament adapter to switch to a 5/8 x 24 thread . Works great. Now i have more muzzle brake options to try.

Muzzle device seats directly against barrel shoulder maintaining full thread joint strength and providing more accurate alignment to bore. Internal and external threads are single point cut in same operation to tight UNEF Class-3 tolerances for perfect concentricity and alignment. The M4 muzzle thread adapter is precision CNC machined from pre-hardened HTSR 400-series stainless steel bar for superior heat and corrosion resistance. Allows the attachment of 5/8-24 muzzle devices to a 1/2-28, 1/2-32, or 1/2-36 threaded barrel.image
