Necrococker Full-length Body

Nummech's "Necro-cocker" body represents the most complex 3d machining present on any production marker body. The Necrococker body was modeled using an MRI scan from a human spine which was then weaved throughout a lightweight autococker shape. The unique skeletal milling pattern is designed to carry onto different parts of the marker to create a highly unique appearance for the matching front/back blocks. All components are individually milled along with the marker body to create a completely seamless appearance.

Full-length body details: The "full-length" platform represents a classic Autococker look and feel.
Necrococker full-length cosmetics consist of spinal bones laid on both the front block and back block, milled along the beavertail area. A milled bolt pin and beavertail adds to the cosmetics.

Nummech's customized marker bodies are manufactured entirely in-house which allows new levels of customization beyond any factory marker. The body enhancements and milling patterns cannot be replicated on factory markers. Nummech bodies are fabricated in small batches, making them highly rare due to their limited production. Each body is engraved with an individual serial number milled onto the body underside. The engraving is permanent and will not disappear after re-anodizing.

    Features:
  • Matching cosmetics on all included parts
  • Asymmetrical 3d milling on all matching parts
  • Integrated feedneck boss; compatible with Empire latching feednecks
  • Offset feedneck to reduce last-ball-bounce
  • Front block is pinned to maintain absolute alignment with body (pins included)
  • Lower bore is honed 0.700" for use with most 11/16" valves.
  • Upper bore is honed 0.689" for use with 2k-style bolts.
  • "Fast-cocker" barrel threads

Description of production changes: Full-length Autococker bodies (various styles)
Batch 0: Identified by no date engraving on the bottom. Bodies from this set are considered pre-production due to limited numbers. These bodies have side-locking set screws for the three-way and ram, but the locking screw holes were removed for future bodies. Most of these bodies were Pyrocockers, except for two prototype Necrocockers (they do not have special engraving).
Batch 1: Identified by engraved text "2019" on the bottom surface. The body blanks were made in June 2019 whereas the cosmetics were applied in the later months. Includes both Pyrocockers and Necrocockers.
