"How can you give a 3 star rating because you didn't notice the bold headline? disregard Taylor's review.

These helped out so much along with aftermarket Hi flow magazine valve and even with .32 gram bb's I started getting at least 150ft range out of my Hi-capa.

"unlike the mass flow gas valves, these perform perfectly in the TM MK23!! Increased my fps by 20. Works great with fully upgraded TM MK23 maple leaf crazy jet ML 50 degree autobot.

"These genuinely help efficiency. With the same HPA pressure, and just this part, velocity went up a consistent 5 fps. Evike customer service did an excellent job with a slight issue I had. Way to go Evike! docB
