I just recently acquired a 527 Varmint MTR in .223. This model does not have a CZ set trigger(wish it did). It has an adjustable down to about 2.5# Not low enough for me.However It is crisp, and it does pull consistent 2.5 on the scale. Do any of you know of aftermarket support for this trigger? Any pointers on manipulating springs? I cant seem to find anything .
