Does any know who made triggers for these guns; I am sure someone must have. I have a 52b action that i am planning to build into a 177 HRM. Somehow I've lost the sear for it, have you priced parts for 52s on e-bay, it's amazing. I bid 150 for a 52 bolt and was outbid! Why I need a bolt is another story that I will post some day. :cry:
