The bix is extremely well made.
It also has tuneable firing pin catch distance which I recommend to slightly overdo (set it that it works with grease and quick bolt use and then put some more twist (1/5 to 1/8) into it, mark the screw with witness marks and then apply loctite)
Mine (T3 trigger fit on a Quad) is at 4.2 ounces / 120g.
Nowdays as I shoot mainly MR223 stock trigger that just runs better the more dirt goes in, I feel like I went a little bit too far with the BnA. But it is still nice to shoot with it and there are no regrets, I just need to tune it to higher weight.
Today I would perhaps start by polishing the stock trigger as I see trigger manipulation as a skill in itself, not a feature of the gun. Ofc I have not ever even touched cheap guns so I do not know how low you can go but the baseline of polished stock trigger should do. And for BR and positional shooting I think the BnA is a really nice advantage (not my cup of tea).
