Looking to replace the trigger assembly in my AR-15 with a lighter weight,single stage. Probably something around 3-3.5 lbs as I hunt with my AR’s calling Coyotes & such. Any thoughts on best bang for the buck,or brands to AVOID? Prices for a drop in assembly seem to run from less than $100–to $500(or more ?). This is kind of a “budget” AR..so I see no sense in spending over..say $150 or so? I figure tomorrow & Friday some deals may come up,so this would be a good time to do it ?
