And at 650 to 750, the valve will still cycle and shoot a paintball at 300 fps?

Yeah, what you're looking for is shoot down though. While classics tend to starve under 800 psi, the RT circuit helps the RTs along at lower pressures. However, with all the variations in setups and valve conditions there's no hard line in pressure that works or doesn't. With a ULT, I wouldn't go under 850 psi. With the stock RT on/off, you can go lower. Classic pump mags can run around 650 psi, but when the pressure gets down there, that's when you start to see the pressure curve of the bottle reg over-lapping with the response of the valve reg. If your recharge time is suffering, usually your consistency will suffer too because it means that you are shooting while the regs are still adjusting.

We did accidentally try to tune a minimag without a reg pin on a low pressure bottle once. It always shot around 250 with poor consistency, regardless of what you did to the valve reg. That was because we were shooting off the bottle reg only. doh!

When you have a new-to-you mag, we generally tell people to trouble shoot them with a good 850 psi bottle (with a reasonable amount of air in it). That avoids some lube/wear-in/response problems. Troubleshooting with low air is generally a waste of time.

Besides, putting a good bottle on mag makes a wonderful "snap".

Higher pressures mean better recharge times and that means when you don't do your part and get lazy on the trigger release, the valve can still get enough air for a good shot. If you have poor trigger control, low bottle pressure will contribute to the problem.

Thanks a ton. Another quick one, what's the going rate for a Classic R/T. The one with the hardline.

Around $200. Obviously lower lately. That black one you were looking at was nice.

The main problem with Classic RTs is that you need to like them almost as they are. They are not so easy to mod.

People tend to like the shiny bodies and the double frames. I put a single frame back on mine though.

really depends on condition... id say 150-200 depending (assuming its in functional condition).

Can you put different frames on them?

No. The frame on it is all AGD or anyone made for it.

I thought you could just drill out the field strip hole on any mag frame and use it on an rt classic...

Ahhh because of the thicker grub screw I'm assuming...

You can, don't screw it up though.
My bad...PTP, Gripstick and a few others did make aftermarket frames but any automag frame can be drilled to fit. Messure twice cause you can only cut once.
