Although this a good spring, this happens to be almost impossible to install for me. I still haven’t gotten it to seat correctly. The rate is so hard it bends the internals where it won’t catch correctly at all.
I was wrong, this spring is almost too much for the takedown, installing it traditionally caused jams and failures. You have to prime it before you install the whole mechanism, otherwise it won’t function. It would really help if instructions were listed in the description for future buyers. Performance is incredible, but installation is more troublesome than it should be, don’t bother if you don’t have much modding experience.
this spring is too strong for the Takedown, the internals are too weak for this springload and will fail to catch every time, don't bother with this at all
Super new to this hobby but I cannot think of a better first mod. Everyone I’ve shown is blown away at the power increase this spring gives the blaster! 10/10 would buy again and the shipping only took 3 days! Super easy install. I cannot wait to buy more products from this website!
I didn't realize that this was a K25 when I ordered it. I was just looking for an upgrade spring for my Takedown build. Pleasantly surprised by that. Its a relatively easy spring to install. The blaster reassembly is a bit difficult though. Tricky to get the inner workings to align just right and get the shell closed. From what I've seen so far, it provides a decent power boost.
