  • For GBB & VSR-10 Unbridged barrels

If you're seeking maximum HOP-up performance and are committed to using heavy BBs, the Maple Leaf 2023 MR HOP Bucking for VSR/GBB belongs in your build.

MR stands for “Maximum Range”, a design based on home-brewed R-HOP buckings, intended to prioritise range over grouping size and is best used paired with a Maple Leaf OMEGA or OHM HOP-up nub. Compatibility-wise, this version of the MR HOP is designed for unbridged VSR-10 and GBB pistol inner barrels but as always, a certain amount of expertise and tuning may be required to install it, though it will be far less work than the R-HOPs of old!

  • TDC HOP-up mod set
  • Requires extensive modification
  • For VSR-10 & VSR-10 clone sniper rifles

If you want to push your VSR-10-based sniper rifle to the absolute pinnacle of accuracy, a TDC mod should do the trick! The Hades Airsoft TDC HOP-up Unit Set for VSR-10 Sniper Rifle is designed to replace the original HOP-up arm and adjuster, providing direct pressure to the top of the HOP-up nub and bucking to eliminate side-to-side shot deviation.

Installing this TDC unit will require some extensive, irreversible modifications to your base sniper rifle, so we only recommend this set for those who are confident with power tools and have a decent level of Airsoft technical knowledge.

The unit requires you to drill a hole through the top of your outer barrel using either a 5mm or 5.5mm drill bit and the included drill guide, inserting the guide into the stripped outer barrel to ensure the hole is drilled in the right place. Hades also recommends that when the modification is complete, that you glue the TDC unit to your outer barrel using super glue or another strong adhesive.

If you are the type of sniper that likes to get their hands dirty with modifications and you want your VSR to outrange and outshoot the rest, this kit will do it!
