Re: I needed a 22 beater gun, guess what i got?
If you're looking more for function in your mods, you should probably look into the MCARBO spring kit found on Ebay. Lightens up the trigger considerably. While you've got it apart, take the time to polish up the internals. Using 1000 grit sandpaper you can clean up the bolt and remove paint over-spray from inside the receiver. Some have said they had problems inserting and removing the magazines. I lightly sanded the magwell with 1000 grit. Just enough to clean it up, and mag changes are easy. Diversified Innovative Products offers an upgrade trigger and trigger guard that have gotten good reviews. By now you've gotten away from the "cheap beater" concept, so I'll plug the beautiful Boyd's laminate stocks (~$99) for a nice drop-in replacement.
