This is sort of a re-cap on what I posted on another thread here on THR.
I love my 10/.22. Here are some of the mod's I've done on my factory original condition, bone-stock, standard barrel 10/.22:
Bed the action
Milled the bolt face to .043"
Free-floated the barrel
Installed aftermarket hammer and polished everything in the action
Installed Bolt Stop Buffer (from Weaponkraft)
Auto bolt release modification
Adjustable barrel tuner
Fire-lapped the barrel
Installed bipod mount on foreend
Installed trigger pull stop screw
Refinished the stock
As you can see, I had a lot of time on my hands then and was kinda bored. The only things I spent money on was the Aftermarket hammer and Bolt Stop Buffer; everything else was just stuff I had laying around from other projects. I also have a friend with a mill who did the machine work. Oh yeah, I also put on a scope that was donated by another rifle in my collection.
The gun is much more accurate now with all brands of ammo I use, except for Remington value pack, that stuff is filthy!. I am still searching for a good brand of ammo other than the super expensive "Match" ammo, but, unfortunately, my time now is limited. I did not do any scientific "Before and After" comparison by measuring group sizes or anything like that, but it is much better just by judging with the naked eye. The only thing left to do would be to get an aftermarket replacement barrel, such as Green Mountain's, but I'll save that for another 10/.22.
