Description

Anti Bounce Weight

Has serration for forward assist which extends a bit back to impact buffer, slowing down the bolt. A Rubber Pad can also be installed to further reduce rearward travel impact.

A separate Locking Pad is fixed in place with a piece of filament and soldering iron, can be rotated or replaced when worn out or milled from more durable material.

There are two versions: 

  • ABW Solid is intended for printing with no infill, later to be filled with metal powder;
  • ABW Slots has two ⌀5 mm and one ⌀3 mm slots intended for inserting metal rods, max length 45 mm each.
     

Sear Trip 

The cutout is in the same spot as in the original BCG. The bottom is flat to better work with sliding sears. Lugs in the middle force it to reset during bolt travel.

Check out my other things for 22LR and happy printing!
