Red dot slipage

Any tips for keeping my red dot mounted on my nitro piston pistol from sliding to the back of dove tail.  Iron Hand

Does the rail go all the way to the end of the receiver, or does it stop? If it stops, you could  either mount it all the way to the rear and/or add some dovetail-to-pic adaptors to take up the slack.

If that's not possible, I'd take a close look at the rear of the gun to see if there's anything solid that can be drilled and tapped. Maybe the cover for the spring. Something you could screw a stop to.

If all else fails, I would look at getting a small adapter and tapping it for a stop screw, and put that behind the dot's mount. I don't know how thick the receiver on the gun is, but if it's thick enough to mill dovetails, it's thick enough to mill a shallow hole with an endmill. Or you could even just file a flat notch across the top to catch the end of a stop screw. File the end of the screw flat to make sure it catches, securely. Maybe you already have a rail adaptor or a scope ring that has a stop screw. You could cut the top off a scope ring, sand it nice and flush, and use that as a stop.

If you don't mind taking the entire gun apart, you could silver solder a stop onto the top of the receiver with a MAPP torch or possibly two.

edit: Ne'ermind all that. If the rail goes all the way off the end, I imagine you could take a hammer and punch and peen the rail at the back to act as a stop.

Its funny that I just finished grinding down a cheap mount just for this. It makes me feel good when some else suggests something that I have done or thought of. This nitro pistol has some beans to it as far as recoil. I have also soft bedded it also . It decreased the felt recoil quite a bit shoots pretty good now with the few mods I have done.   Iron Hand

My Ruger Explorer is beast, too. My much stronger Venom has no problems. My Explorer is dead nuts accurate, but I have to figure out where the zero is each time I retighten the rings. About every 20 shots. Once I spend a few shots figuring that out, I can sweep a row of pellets set up on a block at 9 yards. Then I get to start over, again, from scratch.

It gets so old putting up paper, I am getting pretty good at figuring out my zero-of-the-hour by taking some calculated shots at small objects, like playing a game of battleship.
