    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?

    I assume you are using a weaver or other rail screwed to the top of the Ruger 10/22 receiver (???). If so you can shim the back of the rail to point the scope at the point of impact of the bullet.

    Set the gun up rigidly in a rest pointed at a 50 yd target using the barrel open sights. Loosen the front rail screw and really loosen the rear. Set the scope elevation adjustment to be in the middle of its range of adjustment and attach it to the rail. With the gun rigidly supported slip shims (feeler gages can work) until the gun and the scope are both pointed exactly at the target. Find a set of shims that give you the measured shimming and tighten everything up.

    The link you posted is a part that MAY solve the problem without resorting to the shimming. For $13 it is worth the risk to try it. This part points out how inaccurately the Ruger 10/22 is made. I have shimmed the rail on one of my 10/22's. I have replaced the Ruger barrel on the other with Volquartsen's heavy barrel with a mounting system for the scope that cantilevers the scope over the receiver from mounts on the barrel rather than the receiver mounting of the scope rail. The latter gun will shoot 1/2 inch groups all day long if I do my part. Amazing to me, considering how crudely the 10/22 is made!

    I think I'll give the block a try. I don't think $13 will break me. If it doesn't work I'll try shimming the rail. Thanks.

    I would like to know the brand of scope and mounts and model 10/22 first.
    I am far from some specialist here, but having owned 10/22`s since the 1960`s; building, customizing, tuning, hunting and just about all in between.
    24 inches low at 50 yards seems extreme.......

    That block is not going to get you close, basic math will bind the barrel long before you gain $13.00 plus shipping.

    Has the factory block been off??? Adjusted?? Tightened?? Untightened??

    Action screw over torqued????

    That is serious barrel droop.........

    There are several more too.

    Seems it`s always a bad RUGER!!

    My 10/22 has a weaver rail and tip off Redhead $50 3-9x 30 I think and from the get go it was on the board.
    30 clicks up and over and voila, on the money ever since.
    Stock 10/22 made 1981 or so.
    Did another for a friend yesterday, new 10/22 stainless, same scope similar results.

    See responses in red. I picked this up used. I thought I would try the home version of the block today by putting a small washer in between the block and the barrel and tightening it back down. It helped quite a bit. I think if I can find one just a little thicker I may have the problem fixed.

    Well, that explains everything... This is where you start over or extend this problem.
