I have a Rifle Basix Sav II on a 10FP,came w/ Accutrigger) that I am currently shooting and that I put on myself per their video instructions. I have a SSS trigger on a 110,pre-Accutrigger) that I had SSS put on while the action was in for a tune-up. As such I can't directly compare the installation. I was a little surprised that the Rifle Basix instructions expected me to salvage parts from the old trigger,can't recall which ones right now, been a long day) and incorporate them into the new trigger. Might have been the safety bar and bolt release tab, but seemed like there was something else. The SSS trigger is on a gun that is waiting for stock work so actual field use I can't comment on. The Rifle Basix... well, I'm a litte frustrated with it right now. The design has four adjustment screws easily accessible thru the trigger guard slot, which seems like a great idea, until one realizes that to get to said adjustments you have to remove the rear action screw,unless you modify the trigger guard) to do this, and that the adjustments are of the flavor where you have to 'hold' the set screw where you want it set, and then tighten the lock nut,sort of a jam nut arrangement), which is pretty damn hard to do,I'd say pretty close to impossible) with the action in the stock.
The reason I said I'm getting pretty frustrated w/ this trigger is that I've attempted locking the screws in place by applying some fingernail polish and tightening them, only to have them come loose again. The fellow at the other end of the phone line for Rifle Basix suggested the following 'fix'... to squeeze the screws in a vise to deform the threads slightly so as to create some 'drag' so they don't turn as freely. Uh-huh. Not exactly my idea of a good idea, though it may work. The problem has reared it's head for me in the form of the damn safety engagement screw screwing in and I shoot a string w/ a 4 oz. 'first stage' and a 4 lb. 'second stage' as I try to pull past the safetly,not much choice when it happens in the middle of a string of timed fire). Fortunately I can back the screw out after I pull the rear action screw out between strings... fun. Happened *three times today alone* at a 3/6/9/10/10 F-Class match.
Previously I'd not wanted to use Loctite on that small of a screw; now I'm about ready to use friggin' Super Glue to make that damn screw stay put. Speaking of which, I might as well go glue that SOB in place now while I'm thinking of it.
YMMV,
