Things I liked:Price was in budget, two pinch screws for the dovetail mounts, four screws for the scope tube clamps, having an arrestor pin, and of course the Beeman name. Things I would have changed:Change the arrestor pin to a solid pin instead of the coiled metal they currently use. What others should know:The arrestor pin bent from the recoil of my Gamo Bone collector. After many shots rear scope mount was off the dovetail rail. I cannot say that the pin was installed to the proper depth as I paid a local gun shop to mount my new scope & mounts and sight it in. The gun was not really sighted in so I'm guessing they didn't push the pin down completely. However a solid threaded pin would not have done this. Luckily I found the MFR of these from another reviewer so I was able to find some instructions for these things. It would be nice it PyramidAir would have MFR links for the products they sell. Anyhow, I was able to push the pin out and mount the scope again. I'll report back and update my rating if this fixes it.
