ZRODelta precision mounts at Charlies Custom Clones

ZRO Delta is the rebirth of a niche scope brand, and in this case, the reviews are finding that the machining quality and zero hold has improved.  Charlie's is a bit of a scope and mount snob.  This is a small niche company in an otherwise crowded field, but the engineering, fit and finish are impressive, and worth a try.

ZRO Delta manufactures quality optic mounts and firearm accessories. The DLOC system uses six cross bolts and spring loaded horizontal clamp.  

One piece, two ring 34mm scope mount machined from 6061-T6 aluminum and type III anodized matte black. Uses the DLOC mounting system for quick detach and static mounting, and provides return to zero capabilities.

This mount is shop / show demo.  It has very minor signs of handling marks, and is grade A to A-.


  • One piece, precision machined body
  • Cantilever body and ring allows scope to be mounted either direction providing additional eye relief
  • Scope will maintain zero if taken off for storage or other purposes, providing true ‘Return to Zero’ accuracy when re-attached
  • DLOC system utilizes sixteen (16) engagement points with six (6) recoil lugs allowing our mount to grab more rail than any other mount on the market
  • Heavy duty springs allow for solid retention as well as one handed manipulation
  • The extreme grip by the DLOC mount allows user to only hand tighten retention knobs or torque to spec
  • Designed to allow for quick detachment/attachment
