So, today I put a Volquartsen hammer, auto-bolt release, and upgraded ejector into Heather's 10-22. Her trigger was so heavy that at Appleseed she was using two fingers to pull it by the end of the day (and still shooting Rifleman scores! hrm... Note to self: next time I do an upgrade, I should mix some sand and loctite into her trigger to slow her down...). I don't have a scale to weigh the trigger, but I think it would be fair to say that it was 8 lbs+ prior to the upgrade and now it is half that or better. I also threw an extended mag release onto the rifle. It was also a good chance to spray down the innards with CLP and give the rifle a good scrubbing while everything was stripped down.
My 10-22 got a set of nice TechSight TSR100 aperture sights with a dollop of loc-tite. I have an extractor to put into it as well but haven't done so yet. It already has a Volquartsen hammer, auto bolt release, and the extended mag release so that was all good to go. I have another Blackhawk Axiom Stock on the way so that both rifles will have identical adjustable stocks allowing us to switch and use either one... That way we have one scoped and one with irons.
Both rifles are going to the range tomorrow to verify functioning and to get the new sights zeroed.
