Allows for quick refill Pressure release valve

Reverse the connection of the tube and quick connect valve. Make it cheaper. Hardware stores carry high pressure tubes and valves as well that can be made for half the price

Great product, but I reversed the tube and fill valve in order to accommodate for the wider muzzle break on PCP airline.

Good product, well made and easy to use.

The bulk tank adapter did not come with any gasket or seal of any kind, I had to improvise in order to get a proper seal at the tank and stop gas leakage. Also it would be nice if there was a 6" piece of hose between the bleeder block and the quick connect.

Using CO2 limits the velocity to a average of 600fps in my .22 cal Marauder, this is great for target shooting but not adequate for hunting.

John Nov 05, 2016

With 14.3 gr Crosman Field Hunting pointed pellets my port tuned .22 QB-78 CO2 rifle produces from 8.5 FPE to 14+ FPE over at temp range of 65F TO 85F. If shoot faster than once a minute, there is a progressive energy (velocity) decrease. This is especially noticeable as the CO2 charge gets low. At about 75F this pellet has 10.5-11 FPE. At this temp the JSB 18.2 gr is right around 12 FPE. As a comparison my Benjamin Trail NP .22 produces around 15.3 FPE with the Crosman pellet.

Poorman Plinker Oct 10, 2015

At 75 degrees CO2 produces 900 psi. The most psi you will see out of co2 (under normal fill amounts) is 1,200 psi. There is a direct connection between psi and pellet velocity in unregulated USA airguns. So 900 vs 2900 in the case of the Marauder; 900 vs 2000 in the Discovery. Not hard to figure.

Len - Does using CO2 also reduce the velocity in the Benjamin Discovery .177 ?

William Feb 11, 2014

I applaud the details about speed. This kind of information allows people to make more informed decisions.

It's simple to operate. screw in a co2 tank, attach to gun, open valve. Yeah, it's that simple. Don filling, close valve, open bleeder, detach from gun and tank. How much easier can it get? The down side is you need to pack it and a tank of co2 when you hunt if you are going on an extended hunt if you don't have a pump.

Fairly simple. I'm not quite sure why it needs a solid steel block for a bleed valve but it works.

Handy bit of hardware for the Discovery. I doubt it would work on other guns. Looks like the connect might be a propietary attachment.
