ZCI V2 Aluminum Ball Bearing Spring Guide

This will fit into a G&G GR15 gearbox with slight modification. The pegs need to be shortened a little, but more importantly the tabs need their round shape flattened out just a bit so the guide sits down flush in the gearbox.

On my personal setup I saw +4fps over the stock G&G guide.

No durability rating yet, but I would also recommend loctite on the screw.
