Thread Protector – 1/2-28 TPI


In stock



This Thread Protector is threaded 1/2-28 TPI and is designed for use with our stubby barrels.  It’s made of steel and finished in manganese phosphate, the traditional dark gray/almost black parkerizing of the MAC series guns.  It had an O.D. of 5/8″ and the length is .600″.  It is smooth our the outside except for the outer rim which has slight knurling for ease of grip while removing.  Although we created this thread adapter for use with our 1/2-28 TPI threaded barrels, it will also work with other barrels thread 1/2-28 TPI.

Note:  Barrel and upper are not included.
