3D model description

  1. Front barrel adapter for attaching flash hider/ tracer unit.
    will need a metal 11mm / 14mm adapter (designed with a rocket barrel adapter ) and a 4mm grub screw to secure.

  2. Stock adapter for aeg buffer tube.
    You can either keep your specter M4 front wired or rewire to rear, I removed the block on mine and cut a spring guide down and inserted and glued the back section in the block to act as a nut for a buffer tube screw then made a hole so the wires passed through and exited the block just under the rear. (will need a old spring guide, with inner thread or a 5mm nut, 80mm buffer tube screw need to file shorter if needed.

  3. Rear Sight to replace original if fitting stock adapter.

  4. Front rail 4 slot
    This fits over the oval part the old foregrip sits on and uses your original screws from front grip.

  5. Front rail 7 slot
    This fits over the oval part the old foregrip sits on and uses your original screws from front grip.

  6. Rear plate to replace lost one.
    simply fits into rear receiver with no additional hardware except maybe some double sided adhesive.
