Solid upgrade springs that have been used for years in the industry. They are a staple for upgrading N-strike era blasters and their successors.
While I initially got this spring for my Longstrike it won’t fit without Retaliator internals. So instead I used it for other blasters that I knew would take it until I had Retaliator internals. It’s a work of art and performance and I love it.
Installed the 7kg spring and a stronger catch spring in a yard-sale Retaliator. I also replaced the o-ring, removed the locks so it can be de-primed, and greased everything. I'm getting about 104 fps with the extended barrel on, 114 without the barrel. I'm pretty happy with that. I left the AR intact since it doesn't start to restrict the airflow until the dart has already left the chamber. One note about this Retaliator, the two-piece muzzle interfered with the barrel inside. This one had such a poor fit that when I stuck my finger in the bore and withdrew it there was a very noticeable lip all the way around that was occasionally catching darts.
Works as described and cut just right to fit in my retaliator. I really recommend this spring. It's really powerful but not too much to where you can even pull the slide back like the 12kg spring. (To be fair that spring is meant for really strong people).If you cant figure out how to get the spring in because its so strong, put the spring in the retaliator to where it is still sticking out of the back, then close the shell but not all the way so you have room to push the spring in from the back. That is the easiest way to do it.
The power increase is significant, and the install should be fairly straightforward if you've modded a blaster before. It does make the prime fairly uncomfortable over prolonged use, so I would recommend putting some grip tape on the slide, or getting a pump-action kit if that's in your budget.
