This set includes four different recoil springs and four different nozzle return springs to tune your AAP-01 into a monster!
Green gas, HPA, Drum Mags, Short Mags, Long Mags, Shortstroke kit Etc. There are countless AAP-01 setups possible, and we noticed every setup acts differently. Your temperature conditions also play a big role in how your AAP-01 works, so we decided to release an ultimate set of eight springs so you can tune your AAP-01 based on the parts and gas you use and on the temperature conditions where you live.
