Stainless Steel Tuning Spring for T4E .43 Pistols

Walther PDP .43 big difference and the snap noise from the blowback is excellent. Found the PDP magazine cap was loose and wouldve been leaking O2 if i had not gone to change. A failure waiting to happen. You’ll now only get 24 shots or x3 magazine loads. But well worth it.

This really improves the already great Glock 17 Gen 5 marker

I've seen this spring reviewed on a YouTube video and I was happy to find on Modern Combat Sports's website. The install is straightforward (there are a few videos on YT) and this improved the accuracy of the paintballs due to the increased FPS so I would definitely recommend it. The delivery was quick enough unlike my first order but this will be another review :) The quality of the spring seems the same as the original one but because it is softer it allows the valve to close slower and thus releasing more CO2 which in turn keeps the paintballs flying straighter for longer.
