2k Cocker, Chrome ANS Pneumatic, P&P Front Block, ERGO Reg, Dye Titanium Barrel, Nickel Lightning Bolt, Shocktech Chrome trigger frame, Kapp DZ Cradle, Nitro Duck 68/3K
Very nice finish
Very low operating pressure
Quick and pretty much bomb-proof
JackHammer II is easily rebuildable... IF you ever need too.
Compact (but then amost all aftermarkets are)
Overall light weight
Ram could be slightly larger to act as a LP chamber. The LP nipples does get loose once in a while, all you have to do is tighten them slightly.
I don't have the bolt-on version, I have all the ANS Chrome components but it is mated to a P&P lighten front block and a ShockTech banjo Bolt. Has work flawlessly so far. The Chome finish is done very nicely. Operates on pretty low pressure and even thought the mini ram is small, but it has worked without a hitch especially in rapid fire.
