Minor modification on closed bolts, but could use documentation
I'm extremely impressed with such an inexpensive mod to my setup. I was skeptical because of the price, but I figured at $15, I couldn't go wrong. After installing the bolt, I was able to dial my pressure down to around 300 psi...about 100 psi less than I could get with the Red Bolt. It also shoots much smoother and quieter.
Previously I couldn't shoot 25 paintballs in my EXT eForce at full auto without breaking a ball. Today I went out and shot approximately 200 balls in full auto with no breakage. I'm a believer.
I did have to remove the white plastic ring that fit inside my Red Bolt to make this work, however after I removed it, the fit was perfect. I really would have liked some documentation to instruct me on this, though.
I will report after I've used it in play, but these preliminary tests make me extremely happy.
Can't go wrong on this upgrade. It's one of the most inexpensive accessories you can buy in paintball, and it really improved my gun.
