Every day we have customers tell us that they like the rivet type triggers, but that they're a pain to replace in the field so they need to buy the bolt-on type also. Our Minnesota Brand triggers can be used with a bolt or a rivet. Sturdy one-piece crimp-on bracket & trigger wire supplied with a rivet and a bolt (use either one) for easy replacement in the shop or in the field. A quality product at a very economical price and they fit any brand of body trap.
