I'm looking at upgrading my trigger from my stock Bushmaster single stage to a two stage trigger. I looked at drop-in's, I specifically like the idea of the flat Chip McCormick trigger pack, but was curious how an enclosed trigger pack would hold up to duty use.
I'm afraid a pack type trigger would be more susceptable to damage and peformance problems with a hard use gun if it were to get dirt or other gunk built up within the housing itself.
If this is the case, I'll go with a cheaper traditional design, probably the RRA 2 stage. Anybody have any experience/thoughts on this?
