This bolt is a direct replacement for the Piranha marker. The bolt is constructed entirely of delrin so it is extremely light-weight and requires no lubrication. The bolt has an "open face" for high air flow, angled intake, and weight reduction to increase maximum cyclic rate.
The Alamo City Paintball Piranha Delrin Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
None for Piranha, but I have used other derlin bolts for Spyders.
Pirahna Evo SE (with Evil Detonator Reg)
Evil Driver Barrel
Evil on/off ASA
AC Derlin bolt
12v VL Revy
LP Crossfire 70/4500
With or without O-rings
Two detent slots
Flush cocking turns into rear cocking
I got this as one of the first upgrades for my Evo. I spent only $25 shipped on this bolt compared to the $30 and not shipped for the Boss Bolt WITHOUT two dentent slots. Plus, it seems EVERYONE has the Boss Bolt, so I just wanted to be a bit different. The Alamo City (AC for short) looks to be lighter anyway. I really wish I had the two to compare side by side.
You can get this bolt with or without o-rings and in different colors. Just a couple different fun options to make your marker your own.
That's all there is to this bolt. It's an easy drop in upgrade, or close to it anyway. You do have to cut the plastic ring off the cocking rod to get it to fit. It performs great and I have had no major problems. However, my flush cocking turned into a rear cocking (the rod will jump back as you cycle the gun, but it does stay flush when the gun is cocked) and I didn't notice a significant increase in cycle rates. Maybe one or two CPS, but that's it. You'll need a lighter hammer to increase the cycles.
It's definitly a good budget friendly alternative to other derlin bolts and has some nice features that come included that tend to cost more on other bolts. Plus, it's got some bonus features of different colors and with or without o-rings.
So far, so good.
