Has MTP changed the spring eye size on there small BG traps?

No

Working on the smaller traps but have changed the spring eye on the 330s

Hopefully the triggers are tweaked to work properly as well.

Not for me, they are the slowest trap out there and a pain to set!!!.......jk

I have a Bridger 160, which out of the box was truly horrible. The trigger wires would travel nearly 3 inches.......of just flop back and forth hanging loose......before trap would fire. Could not tune it, so replaced entire wire clip assembly with one for a Belisle 220..........and that fixed it. Will stay set, yet fires easy..........and as 160's go, is a real hammer. Don't care much for the safeties, but with new trigger.......it is an effective trap.
