First off, I'm not really into the ARs. I have a Sig 516 and a Sig 716 because I fell into a good deal. I haven't shot either one very much.
I was at the range shooting the 516 for about 100 rounds. Shoots OK; I was trying various ammo that I have on hand. Some groups were nice other ammo not so good.
Overall though, I was really unimpressed with the trigger. It's probably a combat trigger; heavy pull, kind of a gritty takeup too. Might smooth out in a 1000 pulls. I don't want to wait that long.
So two questions. One, who makes a decent drop in trigger that will give me a smooth pull to a clean break? Two, is this a simple watch a YouTube drop in procedure? I'm familiar with firearms and how they work, so if it's a minor deal, I'm in.
