Maple Leaf - M1911 Hop Up Chamber and Inner Barrel Set - 113mm

Maple Leaf hop-up chamber and 113mm tight-bore inner barrel set for full-size M1911 and MEU pistols, built with the Maple Leaf bucking you choose.

It goes into the slide as one pre-assembled unit, replacing the chamber, barrel and bucking together. The 6.02mm tight-bore barrel groups tighter with good BBs.

Each set is assembled to order from parts in stock, so only buckings currently on the shelf can be selected.

Bucking choices: Maple Leaf Autobot, Decepticon and MR Hop in the original and 2023 rubber or the 2021 silicone, plus the 2026 Delta and Diamond in rubber or silicone.

Fitment: Tokyo Marui and KJ Works full-size M1911 and MEU pistols.
