In the fall of 2010, after hearing about the wonderful reputation it enjoyed, I bought my youngest son a Ruger 10-22. Just the standard rifle with the blued barrel and walnut stock. We were immediately disappointed with the factory “iron” sights. Not wanting to go with aftermarket peep sights we opted to attach the factory provided Weaver style scope mount that attaches to the top of the receiver in the pre-tapped mounting holes with the factory screws. I bought a Nikon 3X9 scope and mounted the scope on the Weaver mount with the Nikon provided bases. We headed back out to the range and started zeroing in the scope. At first everything was moving nice and linear. As we were getting close to dialed in, the adjustments started getting non-linear or even moving the point of impact in the opposite direction. A lengthy inspection turned up that the mounting screws for the factory provided Weaver mount were loosening up. Off to the hardware store to buy and apply some Lock-tite. Next range session we got everything dialed in and it became a tack driver.
We don’t get to shoot that often so it was several weeks, maybe a month or two before we went out again. At first everything was just fine then the point of aim started drifting. I tried making some tweaks that again became non-linear and erratic and low and behold, the Nikon mounting bases were walking forward on the Weaver rail. I pulled out the tools, readjusted the bases and cranked down as hard as I dared on the four lock screws. We got the 10-22 dialed back in and had a rather boring but satisfying session of putting round after round into a dime sized hole.
About two months later we went out again. I checked all the lock screws and started shooting. And once again the bases started walking forward after about 100 rounds. Keep in mind that the screws are tight but it still will not grip the groves in the Weaver mount and walks forward. Gave up, went back home. :banghead:
I took the scope off the bases and started looking everything over. I determined there was a lock screw or mounting screw on the front base that could be screwed straight down towards the receiver. Rather than go out and buy Weaver style bases I simply lined this screw up with a slot in the Weaver mount and snugged it against the Weaver mount. My goal was to determine if this would prevent the bases from walking forward and if so, then I might invest in a true Weaver base for the Nikon. We went out, dialed it back in and after about 150 rounds the point of aim started drifting again. I started examining everything and checking for tightness to no avail. I took a firm one handed grip on the scope and wiggled left to right. I had movement. In fact, the entire receiver was wiggling around in the stock. I took out a large screwdriver and found that the main screw securing the receiver to the stock was less than finger tight. I cranked that down and had to readjust the point of aim which was now way off. Just about the time we got it dialed in we ran out of ammo and went home frustrated.
For a rifle with such a wonderful reputation this one sure seems to be a piece of crap.
