got a bit of a problem

[Spider-TW]

Good deal! $15 and an oring.

What would be fun is an EP- or pneu- mag with RENTAL etched on the valve.

I know they were velocity limited. Are they recharge limited in any way?

[thatkidwiththesilverygun!]

yes 270 be4 it starts to vent more, but it wont go any higher... umm idk yet about the recharge but im jus gonna keep it around for parts for my other mag

[Coralis]

I have a rental valve laying around from my mag i had no problems with it reaching 280 fps ... only reason i bought another valve was so i could use a level 10 bolt ( as you can surmise the level 10 doesnt work with the rental valve without modifications to the power tube)

[flyingpootang]

Awesome! Is 270 as high as it can go before it starts venting out the back?

You can drill out restricter in the power tube. Thats the only difference from a rental and classic valve.

As mentioned, you can drill out the restrictor.

If you don't want to, you can get one of the new higher pressure regulator piston assemblies and it will allow you to adjust the velocity higher before venting. If you want to install the level 10 bolt, you will need to drill out the restrictor and probably get a new regulator piston assembly.
