Go to the RifleBasix website and watch the installation video for Basix 2. It's a good instruction. It's a drop-in, in that all parts are included. Mine is installed on a MOD 10FP. It took me 3-4 hours of adjusting and changing pin positions before I could get to where it was not releasing with a buttstock bump. Now I can't get it to fire unless I pull the trigger. Don't know how that would differ with a 10oz setting. I have it set to 2lbs for PRS type and steel matches. I have accutriggers on all my Savages and like them. I don't know what a really good trigger is supposed to feel like. This Rifle Basix 2 is much different, and feels a whole lot "crisper" to me. I'm happy with it.
