Guarder Enhanced Recoil / Hammer Spring (150%) for Marui & Compatible D. Eagle Style series gas blowback

"Okay, so after some time with these upgrades, I've got to say that the gun feels very snappy with them and I am very satisfied that I bought them. However, I did have a few issues, though they did not hinder me too badly

- The enhanced hammer spring was torture to put in. I had to settle for using a small hole punch to hold it together and tape to keep it from flying out without having to have 3 hands and slowly worked the original pin back in from there. I actually gave up the first time and settled for just the recoil spring, but....
- The recoil springs work great and were relatively easy to install, but without the resistance of the enhanced hammer spring to reduce the slide speed (at least a little bit), the Deagle would load the next BB with such force that it would knock it past the hop up and the BB would roll out of the barrel.

I will keep my recommendations narrow to those who like to upgrade and have patience (and probably lots of tools) and say thise is for them.
