Hello I own a Sako Quad Heavy Barrel in .22lr. I am considering using it as sporter class rifle in Bench Rest (UK). The trigger is a bit heavy for such so I obtained a Bix 'n' Andy replacement. The Bix 'n' Andy has a very good write up so I had high expectations. Unfortunately these were dashed at the first hurdle. The trigger fitted onto the rifle without any problems but the top sear of the trigger unit failed to engage with the sear bent of the firing pin. Despite trying all available adjustments nothing remedied this problem. The supplier stated that they had discussed this with Bix 'n' Andy and that the problem must be with the tolerances on my rifle as all the triggers they had were within tolerance. The trigger was returned, the supplier reiterating that the problem must be with the tolerances on my rifle. Has anybody else experienced similar problems? Any advice to replacement triggers that I may be able to source in/from the UK. Many thanks.
