Excellent upgrade - Ballistic Advantage Premium Ruger 10/22 .22LR Threaded Rifle Barrel

This barrel shrunk my groups vs the factory by about 50%. At 25 yards it can punch nearly the same hole with CCI mini mag. At 100 yards CCI standard velocity I was able to do about 1.5 MOA when the wind was cooperating. I can consistently hit steel at 240 yards with standard velocity cci 40 grain as well. The bull barrel definitely adds some heft to the rifle, which is great for bench rest, but it is still in no way too heavy to shoot standing. The extra weight actually makes it more like an AR-15 so if you use it as a practice gun it does help with that.
The install was very easy - getting the factory stock out was actually the hardest part by far.
