Our Stainless Steel crush washers for your firearm are precision machined – not stamped – by highly skilled, true craftspeople in the USA.
The are used by premier AR manufacturers during assembly of their new rifles.
These crush washers have been re-engineered for a better-looking assembly, and make it easier to assemble because the washer fits inside the standard flash hider wrench.
The major diameter of these washers is 11/16 or .688. The standard diameter of a barrel is .7 at the muzzle. They will fit on any 1/2 thread, no matter the TPI.
They ensure the proper torque because they crush at the correct torque. Then they act like a lock washer to keep the end of barrel device from loosening.
