As you can see from the picture above, these are Weaver 1" Medium mounts for rifles with a 3/8" grooved receiver. This type of receiver is common on air rifles and .22's. I picked these up for $6.97 at WalMart. The Weaver part number is 49192.
The picture above points out the portion of the receiver being referenced as grooved.
The picture above shows in better detail the actual attachment points for the scope mounts.
You may have to loosen the flathead screw on the side of the mount in order to make it wide enough to slip into the grooves on each side of the receiver rails.
This isa side view of both mounts installed. I would just snug up the flathead screws on the side of each mount until the positioning of the scope is complete. You are able to move the mounts up and down the rail, but the actual position and attachment points on your scope will determin the best mount placement. In the picture, mine are about as far forward and backward as you can get.
The red lines indicate the location of set screws. When the set screws are undone, the mount is in two halves. The top half is removed on each mount and the scope is set into place and the top halves put back into position and the set screws re-installed. Remember, don't tighten the set screws down completely until the scope is properly positioned from front to back.
Once the scope is properly positioned, you can then tighten down the set screws (not too tight or you will damage the scope tube), and tighten down the flathead screws on the side of the front and rear mount (again, not too tight or you risk damage to either the rail or the mount).
Here is the whole rifle with the mounts installed. WalMart has scopes from about $39.00 to $89.00. Since this is a .22 and I probably won't be shooting more than 100 to 150 yards at the most, I think I can get by with one of the less expensive scopes. When I get it installed I will document it also.
Hello. What is the length of "This portion is the rail..."?
