Diana Bullseye ZR (zero recoil) mount

  • Fits 11mm dovetail
  • FIts 1" and 30mm scope tubes (use included ring inserts for 1" tube scopes)
  • 4 hex screws per ring secure optics
  • Overall length: 4.75"
  • Length of dovetail mount: 2.625"
  • 3 hex screws fasten the base
  • 0.04" droop compensation (approximately 1mm)
  • 100% recoil compensation
  • Vertical scope stop pin
  • Includes hex wrench

This unusual mount from Diana delivers up to 99% recoil reduction to your scope.  The manufacturer says you can use budget scopes on high-power air rifles because the mount is rigid and has holding power.  Whether you use a 1" or 30mm tube scope, the ZR mounts will work for both sizes!  Plus, some air rifles have droop, making it difficult to mount and sight-in a scope without resorting to shims. This mount comes with 0.04" (1.016mm) droop compensation built in.

Things I liked:

The very solid build and it will definitely save a more expensive scope if you choose to mount it on a air rifle.

Things I would have changed:

The overall size. Its long! It barely fit my UTG Hunter that is 15inches long. Dont even think about purchasing this if you plan to use any type of short tactical scope.

What others should know:

Use loctite on all the screws even the four inside the ring.

3.0 3.0

2.0 2.0

Things I liked:

Great concept

Things I would have changed:

It broke almost immediately. Slide rail fell out. I used hammer to get back in slot. Stop pin sheared off after 100 rounds and can't screw in last bolt threw sheared pin. Spring is shot. Not much higher quality than spring in a bic pen! I'm not exaggerating. Hard to believe PA would sell anything that is guaranteed to break

What others should know:

if you can design one of these that works it would be a hit

Things I liked:

The fit and finish were great, should work great just about the same principle as the old Lyman and Unertl scopes that moved during recoil. Tighten the side plate down good and snug and this thing wont move. I mounted it on a Hatsan 135S QE 30 caliber Springer with a Mueller 4.5-14X scope.

Things I would have changed:

the only thing would be to make it a bit higher so any scope can be used and maybe instead of one spring make it a double setup.

What others should know:

This is something that only time will tell nut I would use it again. watch the ring liners to reduce it down to a 1 inch scope that you don't loose them.

  • Delbert from USA asked:

    Is this a 1st generation model that uses 0.237" slide pins, or the 2nd generation model that uses 0.257" slide pins for snugger fit within the mount block holes?

    • Edward from USA asked:

      Will this mount fit the Gamo Magnum .22 cal?

      • Bruce from USA asked:

        What if I don't need the "droop compensation" that is built into this?
