Paintball

[bryco13]

Just wanted to say hello, I've been lurking and searching the forum for a little bit now, as I just found a brand new sentinel in the box for cheap money, and need to learn about it. I'm not new to paintball, I got my first marker in 94, and have had almost everything since. As I've gotten older, not necessarily wiser, I find myself wanting more guns with less electronics. I was actually looking for a plain old mag when I stumbled upon the Sentinel. I will get pics and possibly a serial number when I receive it next week.

Nice markers. Mine tend to prefer unregged co2, and they run very well on it.

What would you like to know?

It's new, and has been sitting in the box since he won it at a tournament years ago. So i'm gonna have to go through it and see how the o-rings are. I found a nice list of o-ring sizes and owners manual, so thanks to the folks who put that up. I was planning on running it on hpa, and i have a gas through grip, expansion chamber and reg on standby incase i want to try co2. I will get pics in the picture section once it comes in and gets cleaned up.

HPA will fare better on a modified Alias Timmy valve stem, with a flat ground for recocking purposes. CO2 regged to 650psi has given me the best performance on a stock Sentinel, '03 model (tribal milling on the sides, but cylindrical back plug and mini-rail on the top tube).

pretty impressed, put about 50 quick rounds through it after a few drops of synthetic oil on the bolt and into the asa, aired it up (hpa) not a single leak, not a single break, needs to be chrono'd. and damn this thing is loud, lol.
