I just received my scope and b-square one piece mount. There is a large flat head screw sticking out of the scope rail on my airgun. What is this screw for?

Also, the b-square mount didn't come with any type of stop pin and I thought it did. I called them and told the lady on the phone and she said she'd send one right out to me. Didn't ask for my card or anything. I thought that was pretty cool.

My 52 has that too. I thought maybe it was a recoil stop.

What kind of scope are you putting on your 34?

It is a Swift 695M 3-9X40. It looks really nice and I got a great deal on it, at least I think I did.

The scope mount is a B-Square 17101. I thought the mount was supposed to have a stop pin built into it? B-square said they'd send me the stop pin. Where is the stop pin supposed to go? And which hole in the rail does it fit in?

edit: 685M

I ended up putting a Tasco 2.5-10 with a Beeman/Mac1 custom drooper. The scope is decent for 50 bucks.

B-Square sent me the stop pin with no questions asked. They even apologized for it not being in the package.

That screw is a scope stop. I have heard of people shearing them off. I never have. If it is in the the way of your mount just take it off. I usually just remove them. HTH
