Doesn't really increase trigger sensitivity
I bought this product mainly just to reduce the kick of my A-5 and it really did help with that for the most part. Tech-T sent me the special stiffened back spring and the two sear springs with it as well. I didn't even have to look up installation instructions because I know an A-5 inside and out. Instead of doing the way they say in the instructional videos by taking the internals out the back I just took the whole gun apart, lubed the zero kick hammer and dropped it in. The reason I did that was because my two friends who also have this upgrade tried to do it the way the video told them to and had a heck of a time getting everything back in again. After I had the Zero Kick Hammer and springs installed I turned on my e-grip and made sure the trigger was working properly with the new springs and it was. Then I cocked it back and pulled the trigger to make sure everything moved correctly and it did. Then I put the air tank on and dry shot it just to make sure it doesn't skip shots and it didn't. Then the final test was velocity in which I at least needed it to shoot 280 fps. At first it was a tad bit low going between 260 and 275 so I had to loosen my velocity screw a little bit and after that it was fine. It didn't seem to have as much kick, but however I didn't notice any increased trigger sensitivity which was disappointing. Other than that I was pleased with the kick reduction.
If your looking to reduce the kick on your A-5 marker then this is what you want to get. Make sure install the springs included or it won't work. Due to no noticeable trigger sensitivity I give it a 9.
