TOOLLESS ZERO STOP & LOCKING TURRETS

TOOLLESS ZERO STOP & LOCKING TURRETS
Gunwerks LLC

The most elegant and easiest zeroing process on top of leading technology in ballistics solutions

A primary design goal when developing the Revic PMR 428 was ease of use. We’ve all been there with a variety of rifle scopes tightening and loosening screws and installing shims or any variety of shenanigans to set a zero stop. Our engineering team was able to develop a patent-pending, true toolless turret adjustment system that is leaps and bounds above anything we have laid our hands on to date.

ADJUSTING THE PMR ELEVATION TURRET

For setups requiring up adjustment of the zero stop:

  • With the turret in Unlocked/raised position, adjust turret until rifle point of impact is at desired zero
    • If you reach the zero stop while adjusting bullet impact down, skip to instructions below:
  • Press turret down to Locked position
  • Secure the turret from turning with one hand, and using a bullet tip with the other, depress button on top of turret and rotate top of turret clockwise to Disengage position
  • Rotate turret clockwise until internal zero stop aligns to zero on turret
  • Using the bullet tip, depress button and rotate counter-clockwise to Engage position
  • You have now set your turret zero and zero stop
  • Lift turret to Unlocked position to operate


 


For setups requiring down adjustment of the zero stop:

  • With the turret in Unlocked/raised position, adjust turret clockwise down until you hit the zero stop
  • Press turret down to Locked position
  • Grasp turret with one hand and using a bullet tip with the other, depress button on top of turret and rotate clockwise to Disengage position
  • Rotate turret counter-clockwise the amount of adjustment required for zeroing
  • Using the bullet tip, depress button and rotate counter-clockwise to Engage position
  • Lift turret to Unlocked position and dial clockwise down to the zero stop
  • You have now set your turret zero and zerostop


Adjusting the PMR Windage Turret

  • With the turret in Unlocked/raised position, adjust turret until rifle point of impact is at desired zero
  • If you reach the travel limit stop while adjusting bullet impact, skip to instructions below:
  • Press turret down to Locked position
  • Grasp turret with one hand and using a bullet tip with the other, depress button on top of turret and rotate clockwise to Disengage position
  • Rotate turret until zero position aligns to the index mark


  • Using the bullet tip, depress button and rotate counter-clockwise to Engage position
  • You have now set your turret zero and travel limit stop, lift turret to Unlocked position to operate


For setups requiring adjustment beyond the travel limit stop:

  • With the turret in Unlocked/raised position, adjust turret until you hit the travel limit stop
  • Press turret down to Locked position
  • Grasp turret with one hand and using a bullet tip with the other, depress button on top of turret and rotate clockwise to Disengage position
  • Rotate turret back to zero position, plus the additional amount required for zero adjustment
  • Using the bullet tip, depress button and rotate counter-clockwise to Engage position
  • Lift turret to Unlocked position to and dial to the zero position
  • You have now set your turret zero travel limit stop
