Are you looking for more recoil from your AAP-01? Installing a stronger CowCow Hammer Spring will do the trick! These springs come in a set and replace the original part in your AAP-01 pistol.

The set comes with two springs, the shinier one is 140% strength and the duller one is 200%.
- Shield-shaped contact patch
- Flat/R HOP style Rubber
- 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. The MR HOP-up Bucking offers a wider and longer “R-HOP” style contact patch for increased HOP-up effect and extended range with heavy BBs.

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!
