Not more than an hour ago I finished installing a Bushmaster 2 stage comp trigger in my E2S A3 20. This is my first experience with a 2 stage trigger.
I have'nt "live" fired it yet, but, my obsevations are this:
Installation was very easy per the instructions.
Initially the first stage was rough, I padded the hammer and dry fired for about 200 trigger pulls - the first stage cleaned up nicely.
If adjusted properly the second stage seems to let off very crisp and light.
I feel that continued use will only make the action smoother...
I'm off to the field tomorrow to shoot I'll know then, but so far I'm totally satisfied and not dissappointed with the purchase.
