This is a replacement spacer that can be used with the short 1/2″ 5.56 OPS INC™ Brake. The short brake gives you the option of using either a crush washer as were used on the MK12 SPR, or this spacer along with timing shims. For more information about the different brakes, see this blog article.
Not for use with 5/8″ 30 Cal brakes or long 1-/2″ 5.56 brakes.
