**PTR 9C BOLT HEAD NOTE** We are getting emails from customers regarding the issue with standard spec HK locking pieces not fitting in PTR 9mm Bolt Heads. This is because the PTR Bolt Head is up to .007 undersized in the Locking Piece Pocket. They are not made to exact HK specs. We have no control of the manufacturing standards of PTR. We suggest you grind or mill the locking piece to the dimensions of your bolt head.
