Stock Bolt: moderate amount of blowback especially when running above 200 psi
Marker Setup:
B2K: Tantrum chaos, MacDev valve, Zenitram 15 ASA, Bob Long Torpedo, Smart Parts microgauge, microrock with Zenitram hoseless adaptor, NW Riser, Tantrum bolt, Hinge trigger job, Dye Stickies, NW drop, Crossfire 88/45K preset 450psi, HaloB, Titanium Boomstick
Strengths:
-stops blowback
-very high quality
-venturi = gentle on paint
-minimal friction
Weaknesses:
-o-ring adds friction
-shorter bolt=harder to field-strip
-expensive
Review:
I bought this bolt to stop blowback, which it did for me. It has a single o-ring which does the job just fine in my gun, and the quality is very good. I've put about 6 cases of paint through my gun since getting this bolt, and I haven't had a single problem with it.
There is a bit more friction when compared to the stock bolt (due to the o-ring), but I am still able to run my LPR at 75 psi without having any cycling problems. I am running a Halo on a NW riser, and haven't noticed any feeding issues or problems with the bolt bouncing paint back up the stack. The bolt works just fine with my older nylon ball detent without any sticking.
The bolt is shorter and doesn't stick out from the end of the gun at all. Removing the bolt is easy between games, but I wouldn't want to try to field strip my gun while hiding behind a bunker.
I guess the venturi design is supposed to be gentler on paint to prevent breaking brittle paint. I was running a lower pressure (about 175psi) before I got this bolt, so I didn't have that problem to begin with.
Conclusion:
That's about it. It's just a bolt. I would have been happy with my stock one if I didn't need to get rid of my blowback. I did consider getting a Vapor bolt because they were cheaper, but I couldn't find any in stock at the time I needed one. In hindsight, I think I am much happier with this bolt, because it solved the problem I needed it to solve, without causing me any additional problems.
