I did a little work to make my Timney trigger fit, after instalation the set pull was as if it was set for a varmit rifle. I would start to pull and with no resistance, click! I don't understand the instructions well, my meds have changed some, its hard to comprehend.. ****! Dont laugh. this makes me sick! the meds have me screwed up. I cant read a blue print with this crap they got me on. all I would like to do is add some weight to the pull. I love it! it won't misfire or bump fire its just smooth, to smooth. My Springfield is a sweet rifle..all I need is to go to the farm this November.
