Question: Will this fit on a Beretta u22 neos? It has a Weaver style rail.
Document: My Beretta Neos U22 has what Beretta calls, a "weaver" mount in the manual. Even labeling it with a circled "R" for registered trademark. But alas, even though description here says "weaver", in no way, shape, or form will this sight fit on my gun. First, the mount does not come apart so I can't even get the sight onto the rail.
Works great on my Beretta u22 Neos. No problems at all. I have been trying to get my wife into shooting. Put this on the gun and now she's really getting into it. Can't beat the price.
I tried to use it on my shot gun for turkey season, but it would not fit the factory mount I bought for my Rem 870 - the spacing of the slots was way off. It does fit on the AK style rail I bought for my Vepr 308 - don't think this is a Weaver Mount.
I bought this scope for my neos and i love it the only thing is that it didn't fit the rail that was on the gun so i removed the rear sight and put it on there it works great.
The sight worked pretty well. Good value for the amount of money. Only issue was that it has a Picatinny style mount that would not fit the weaver mount on my pistol. Very good build quality for sure. I needed a replacement fast so I picked up a different model at Walmart that seemed to come from the same factory but with cheaper mounts. I would buy this one again as long as I could be sure it would mount.
Scope seems OK. I bought it for a S&W; 22A with a 5.5 inch barrel with an integrated weaver style optics mount. The 2 base mounting screws are do not move. If one was adjustable, could be moved forward or back and it would have fit the weaver base on my target pistol. Unless you want file a new channel in your pistol, this is not the scope for the 22A.It does come with 2 batteries. Looked like a nice sight for the price.
Excuses, excuses.......I mounted the sight on our Ruger 10-22. It appears well proportioned in relation to the small carbine. The tiny mount rail I had previously mounted on the 10-22 required a little modification on the vertical mill, in order to make suitable clearance for the rather plump cross-bolts on the Weaver style mounting system that came with the Leapers sight.
Since so many other reviews have already talked about the lens covers and batteries and other details of this red/green dot scope, I'll just chime in to give an impression of how rugged the thing is. I attached it, using a Weaver-style rail, to an old 8mm Mauser. Given the fact that most reviewers seem to use this sight on lighter guns like paintball or .22 or .223, I half expected the thing to break the first time I fired the gun.
Although what is advertised is Model SCP-RD40RGW, what I received was the newer model SCP-RD40RGW-A by UTG which is NOT compatible with a weaver style mounting rail. I purchased from P Coast Partners. Currently it is being sold by Big T Products. I put 4 stars for this product because I didn't want to tarnish its overall rating, but I really can't say how well this particular product works because I never received it. I left appropriate feedback for the seller.
I bought this sight specifically because the Amazon title says it fits weaver mounts. It DOES NOT fit the weaver rail on my Browning Buckmark Contour 22 LR pistol. The spacing of the tightening bolts does not match the notches on the Buckmark rail.
Answer: yes
