I own Species timmy and I have used it's stock bolt, a shochtech bolt, a check it products bolt, and this kill stick bolt.
2 Species Timmy 1 with Shochtech and one with KillStick
2 70 Stubby Crossfire LP and HP
2 Cases of Chronic
2 J and J kits
2 Hybrid Bumperless Ram Caps
Have to put ball in yourself and loctite it.
The bolt is a great bolt and in my opinion was better than my friends shochtech. I mean this test was mostly the same except bolt and ram. The ram was great also! I thought this bolt might have been a waste of money but I was wrong it wasn't. It was a great buy and even at 30$ it would still save you money for more paint or w/e you need. I would tell people to save the money andget this bolt instead of a overpriced bolt that preforms the same. Shoch tech is a nice bolt but for the price this is a better buy. The bolt has slighty bigger o-rings that makes a great seal and lowered my lpr pressure which reduced a slight kick in my gun which i got to run on debounce 1 again. Has very very very low drag with a little bit of tri-flow.
The bolt is great! For the price it's a super great! 10 all the way. They should fix where the user does not need to provide the ball but other rise were ok. 10!
