FN FAL Gas Plug Assembly

grabcad

A model of the FN FAL's gas plug. This is based off the type "B" gas plug, shorter than the type C but with a cut to prevent the inverted insertion into the gas block that is possible with the type A variant. The model includes the gas plug plunger and retention washer as separate parts; on assembly, these parts would be permanently swaged together to lock the plunger in place. This model was reverse-engineered from a gas plug that I own; I have strived to keep the dimensions as accurate as possible using my calipers, but as always when working without a print, use at the risk of inaccuracy.
