Sorry to bring this back up but I could use a little help with something...
I've had trouble getting my rifle sighted in for about a year and I finally put 2 and 2 together and realized that I've got one of the Marlin recievers that has scope mount holes drilled off-center. I've learned that it's happened with Marlin rimfires and I'm one of the unlucky people to have the problem. Simply put, with the Weaver mounts that I've installed on the reciever, the scope is extremely crooked from the start. If I mount a scope on the rifle and slide the rings out of the mounts and set it standing on a table, the rear ring can be sitting flat, but the front ring has one end approx. 1/16" high. Big problem when you extend that to 50 yards. I know some people sent their rifles back to Marlin and got good rifles back, but what I have is modififed way past warranty and besides, they can't do anything with a re-barreled reciever.
I realized the problems immediately started after I switched from cheap rimfire rings that mounted directly to the reciever to better Burris Zee weaver rings that I put on Weaver mounts. I'm too ashamed to admit what I used to fix the problem, but it worked for enough time for me to eventually get beyond frustrated and get Burris Signature rings.
I've got Burris Signature rings on the scope and probably could fix the problem if I got ahold of another pair of 20 MOA inserts for the front ring (yeah, it's bad enough that both 20 and 10 MOA adjustments don't fix it) so combined I can get a total of 40 MOA out of the rings, but I just don't like the though of that.
Better solution, and here's where my real question lies... does anyone know of a good Weaver-style mount that clamps to a simple 3/8" dovetail? The reciever has a 3/8" dovetail already, so installing the mounts to that (one-peice preferably) would bypass the off-center mount holes and allow me to continue using Weaver-style rings.
I've done some looking and a BKL #558 mount would be perfect, but I don't think they're in production anymore
. Does anyone know of a decent 3/8"-to-Weaver mount that would be affordable for me? Any other solutions?
