Review: This is one of the first upgrades I made to my Piranha when I went low pressure. RJ Skateworks was my first stop in getting low pressure components, and I just couldn't pass up his famous and ever so popular Boss Bolt.

So what makes this thing so great?

Key Advantages:
Gas Efficiency = Better BPS - My last bolt had a venturi head, which, as some of you may know, has a plugged end with holes drilled in it. Since air can only escape through those holes, venturi bolt heads restric airflow. Less airflow means less BPS. The Boss Bolt is open face, which, apart from having no bolt at all, is the best airflow you can get. This bolt required me to turn my opperating pressure down (just what I wanted) to keep my BPS under 300.

Cycle Rate - The Boss Bolt is lighter weight, so it kicks less and cycles faster.

High Grade Delrin - Since this bolt is made of higher quality delrin than most other delrin bolts, the Boss Bolt is less vulnerable to expansion when exposed to oil. In case you didn't know, delrin swells when it absorbs any oil it touches. However, this swelling occures over a very long period of time, usually months, depending on how much oil it is exposed to.

Chamber Wear - No more metal to metal contact inside your Piranha's bolt chamber. Plastic on metal, much less wear and tear.

Ball Breakage - The theory behind the venturi head on a bolt is that the head of the bolt has more spread out, even contact with the paintball to prevent ball breakage. I really noticed no more or no less ball breakage when I switched to the open face Boss Bolt. The inside head of the Boss Bolt is nicely tapered, and probably does just as much to keep from dicing paintballs.

Uses Bottle O-Rings - Some delrin bolts don't use o-rings, simply to reduce friction in the bolt chamber. But the advantage of bolt o-rings is efficiency; they seal the bolt chamber, better directing the air out the barrel, not passed the bolt and out the rear. The Boss Bolt doesn't use it's own fancy brand of o-rings, it uses bottle o-rings, which are easily available.

RJ is THE man - I got in touch with RJ, the maker of the boss bolt, on the PB Nation forum. He replied to my post on LP components for Piranha's. He offered to do a free Ram Air mod for me, and in return, I made an order of LP Piranha parts from him, including of course, his Boss Bolt. RJ is a nice guy, and is full of useful knowledge about Piranhas; he just loves 'em.


Key Disadvantages:
Vulnerable to Expansion - The Boss Bolt may be made of a high grade delrin, but that doesn't mean that it still won't expand when you expose it to oil. It simply expands slower. I'm a grease monkey, and I have a fetish for lubing everything, even if it doesn't need it. My Boss Bolt, after about a year and a half of exposure to my oil fetish, started to have a tight fit in my bolt chamber and my Piranha stopped recocking properly. But since RJ rocks, I was able to send him my bolt and get it machined down free of charge. Now my awesome Boss Bolt is back in action, working better than ever.
Conclusion: One of the best bolts money can buy for your fishy. Plus the guy who sells this bolt, RJ, is a really nice guy. Based on good efficiency, a fair price, a slight expansion issue, but great customer service to make up for it, I give the Boss Bolt a 9.8.

I think you ment FPS where you discuss BPS, just so you know.

Otherwise, good review.
