I was thinking of ordering one of the #18 locking pieces to try in my HK51. Will it alter the headspace? I do not want to spend a 100 if it will mess it up. Thanks. any one know where to get them any cheaper?
It will only effect the timing (unlocking) of the gun, some 51's need them, some don't.
You might try Phil Flack for the LP and, he normally charges less than GM.
