AAP-01 Inner Barrels

AAP-01 Inner Barrels UK

AAP-01 inner barrels at Ebog Designs, for the Action Army AAP-01 / AAP-01C gas blowback pistol. Tight-bore inner barrels from Action Army, Edgi Custom Works, PDI and TTI in 6.01, 6.03 and 6.05mm bores, with brass and stainless steel options; lengths run 129mm, 131mm and 200mm, plus 84mm for the AAP-01C.

A 6.03mm bore is the usual first step up from a stock barrel, and the tighter 6.01mm holds the BB more firmly and rewards clean, well-sorted ammunition. Barrel length has to match your slide and hop unit, so measure the barrel you are replacing; the genuine Action Army barrel and bucking sets are in AAP-01 replacement parts.
