Airsoft M4 Pencil Barrel to Heavy Barrel Front Sight Post Adapter Sleeves

Ended up doing this at the request of a teammate. Apparently MWS-Compatible Government/Heavy cut airsoft barrels are tough to get right now in 20", and pencil was all they could get. So, this adapts the pencil barrel to the Heavy/Gov-cut A2 front sight post.

Pins work fine, as well as the grub screw. You'll need a longer one.
