Does anyone here have expirience using a Elevating Barrel Block Like this one from MidwayUSA http://www.midwayusa.com/viewProduct/?productnumber=914581 for a Ruger 10/22? How much will it elevate the barrel? My 10/22 is hitting about 24" low at 50yds right now and my scope does not have enough adjustment to compensate. Will this bring it up enough that I can actually zero my scope? Does anyone else know of anything else that would help?
