Muzzle Cap, Alpha, Threaded, 1/2-28

This muzzle cap version provides a 1/2-28 threaded boss on crown for adding attachments such as muzzle brakes or suppressors.  This muzzle cap is intended for use ONLY with .223 caliber applications.  The hole through the center is 0.32 inches in diameter, but it should not be used with any caliber over .223 because (1) it would increase the chances of misalignment with the bore which could lead to a bullet striking the muzzle cap, and (2) accessories made for this thread size are often made strictly for 223 caliber applications.
