Things I liked:I like that this Hammerli 850 AirMagnum 11mm-to-Weaver scope rail is very simple and versatile. I have installed this rail on both my Hammerli 850 and my Crosman 1077W rifles. This rail works well converting the 11mm dovetail to the Weaver mount without adding much height. The set screws lock the rail down on the dovetail very securely, and the rail is very stable once the set screws are screwed in.
Things I would have changed:Nothing.
What others should know:The length of the 11mm-to-Weaver rail is 6 inches which matches the length of the dovetail on the Hammerli 850 AirMagnum rifle. However, the Crosman 1077 / 1077W dovetails are only 4 inches long. This rail can be used on the Crosman 1077 / 1077W because the rail's set screws are just less than 4 inches apart. Once the rail is slid onto the Crosman 11mm dovetail both set screws can be tightened against the dovetail with about 1 inch of rail extending past both ends of the dovetail. The initial fit of the rail on the Crosman dovetail was quite snug, and I had to use a soft mallet to tap the rail to slide it onto the dovetail. I'm glad the rail had that extra inch past the back end of the dovetail because I needed to mount a ring on that part of the rail in order to position the UTG 4x32 AO scope at the proper eye relief distance. Using only the dovetail and dovetail scope rings, it may not have been possible to adjust this particular UTG scope to the proper eye relief distance.
Things I liked:Lowest possible profile. Precise tolerances. Rock-solid mounting system for any type of rifle.
Things I would have changed:Add a recoil pin for use on break-barrel guns.
What others should know:I used this on a Beeman R-9. I distrust a scope on a break-barrel rifle using the 11 mm rail with separate rings. I like the Picatinny system because you can anchor both rings in place on the rail so that the scope does not receive any tension from possible ring creep on the rail. I first carefully located and drilled a hole for a recoil pin to be drifted in after the rail was properly positioned on the receiver. I then put some oil on the contact points of the 11 mm rail and then carefully "drove" the Hammerli rail onto the rail of the R-9. I then installed the recoil pin and tightened down the set screws. It was a very snug mating of the two rails; so snug I feared it would get stuck before I could get it fully into position, but it kept moving with each stroke of the light nylon faced hammer. Obviously, your guns rail will have to extend completely to the rear allowing this conversion to be installed, as it must be slid into place. You should also remove the action from the stock.
Things I liked:Mil spec picatinny accessories will work on this.
What others should know:Most rails sold by PA are weaver style with picatinny compatibility. This rail is mil spec, meaning the gaps and ridges are spaced evenly throughout the length of the rail. Weaver rails have variable spacing between each gap. If you own a Airforce gun you owe it to yourself to get this rail. I bought a second as a spare I like it that much!
