Edgi Custom Works - 113mm GBB Inner Barrel - Hi-Capa 5.1

Edgi Custom Works 113mm GBB inner barrel, cut for the Tokyo Marui Hi-Capa 5.1.

In a gas pistol the barrel is short and the amount of gas behind each BB is fixed, so a tighter, more consistent bore is what lifts group size rather than any gain in power. Every barrel is hand-lapped and finished by Edgi to hold that consistency down its whole length.

Choose on this page: material (brass or stainless steel) and bore (6.01, 6.03, 6.05mm). On bore, the tighter 6.01 holds the BB more firmly and rewards clean, well-sorted ammunition, while a looser bore is more forgiving of dirt and BB tolerance. The stainless steel is the harder-wearing of the two materials and is priced above the brass.

Fitment: Tokyo Marui Hi-Capa 5.1. Measure the barrel you are replacing before ordering — length is what decides whether it sits correctly against your hop unit.

Stock size. Every Edgi part is cut to order, so we keep the sizes that sell most on the shelf ready to ship rather than have you wait for one to be made — this is one of them. If you need a different length, material, bore or window cut, order the made-to-order version and Edgi will make it to your spec.
