Ran across your head space video, watched it, and decided to seek out this tier 3 video. I bought my tier 3 job about 3 years ago and it transformed my rifle. I just love it! I recommend it to everyone who buys a 10/22. I'm not a competition shooter, I just like plinking. The tier 3 is so good, It makes me want want to buy another rifle just so I can see what the tier 1 or 2 is like, because I can't believe it could get much better.
The polymer trigger group isn't a bad thing, modifies just as well as the aluminum ones did...and to be honest, those aluminum ones got rough and nasty looking there towards the end, Ruger was cutting a lot of corners there for a while.
