Gas Blowback Internal Parts

The Maple Leaf MR HOP-up Bucking is widely regarded as the best HOP-up bucking offered by Maple Leaf, offering a wider and longer “R-HOP” style contact patch for increased HOP-up effect and extended range with heavy BBs. The MR HOP also uses a shield-shaped groove around the contact patch to allow it to stretch and add to the strong HOP-up effect and an air seal improving C-ring which ensures the bucking is firmly fitted to the barrel and unable to slip or rotate.

MR stands for “Maximum Range”, a design intended to prioritise range over grouping size and the ideal pairing for the Maple Leaf I-Key. This bucking is compatible with Tokyo Marui-based GBB and VSR platforms, WE and VFC GBBRs and as always, we only recommend upgrade parts for those who are confident working on their platform's internals. If you want to extend your range out to the borderline implausible, the Maple Leaf MR.HOP HOP-up Bucking will do the trick!

If you love your SSX23 and would hate to see it out of action, grab the Novritsch Nozzle Assembly Set for SSX23 NBB and keep it in the parts stash just in case! This nozzle assembly is a replacement original part designed for the SSX23 N-BB pistol from Novritsch and is constructed from a high-density polymer. Nozzles are a known failure point for pistols and as reliable as the SSX23 is, it's always wise to have spare parts so you can keep your beast of a pistol up and running!

If your Tokyo Marui ZET system M4/AR-15 needs some steel to keep it strong, the CYMA CGS Adjustable Trigger Box for TM ZET System M4/AR-15 GBBR belongs on your shopping list! This complete trigger box is ready to drop in and contains full steel trigger components which should last practically forever in normal use. The box is compatible with both CYMA's CGS M4/AR-15 GBBR series and Tokyo Marui ZET system M4/AR-15 GBBRs. 

Along with its steel construction, the extra perk of this box is its ability to adjust the hammer stroke strength, translating into adjustable FPS by varying the force with which the hammer strikes the valve knocker. As always, we recommend internal upgrades only for those who are confident in how to install them, but with this trigger box being pre-built, most of the hard work has been done for you!

This set is designed for TM ZET system M4 GBBR mags and should also fit clones of the TM design, including CYMA CGS M4 GBBR mags and Double Eagle M4 GBBR mags.

The Gas Route Buckings are also very useful in the event your magazine develops a leak from the top, and can also help improve gas efficiency should you decide to upgrade your TM or Double Eagle M4 GBBR with a steel CGS bolt carrier group. If you're getting in deep with ZET system GBBRs, this set belongs in your toolbox!
