I am getting completely out of the HK91 clone game. My loss is your gain!
All of these parts were just received from RTG parts. The standard HK locking piece / spring / firing pin were new but i did install them ( no firing) and promptly remove them. Same with the RCM #17 LP. just got it today actually, installed and removed. HK +4 rollers are new as well. everything else in excellent condition.
Looking to sell all of this for 107 shipped via paypal gift
