Benjamin CO2 & Air Fill Reviews

Does what it's supposed to do.

Nothing!

No comment!

Works great, sturdy, good fittings

nothing

HPA is the way to stay

IT WORKS AS IT SHOULD

LOWER PRICE

HANDY THING TO HAVE

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.

Great value, look & feel..!

good construction

CO2 users should get this instead of the one without the bleed valve

it works great!

none

you should get this when your hand pump broke. you still can enjoy some fun with co2. I got my hand pump for tow weeks and broke I should listen those reviews.

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.

Works good as it ahould seems to be of decent quality.

Bit spendy for what it is.

all good.

I think it needs a elbow to make it easier to fill. And a screen type fitting on the bleed port. (just to keep out dirt from getting in.)

I put a longer hose on mine so I could use it with the tank attached to it.

Works well exactly as described. Any issues are user error. If you're going to use CO2, this is your best adapter.

a little expensive, but much better than the cheaper version which has no pressure release valve.(making it VERY hard to loosen after filling)

no

Seems solid.

Add a hose on the output side so i don't have to scratch up my gun with the valve housing.

Be careful when filling a Marauder, as is is very easy to scratch the bottom of the barrel shroud with the clunky metal valve housing every time you fill up. It should have a hose on the output side.

Worked well, well made

Add a pressure gage, needs a little longer hose

Remember when you turn the handle to the right (clock wise) it opens the valve on the tank, when you turn to the left it closes the tank. This is backwards from what we are used to when opening or closing a valve. Because when opening the tank you are pushing a valve stem down, like the valve stem on a tire.

Other than the problem I had the item is well made

when I went to use the adapter it instructed the user to turn the knob over the cylinder counterclockwise to insure the valve was shut off from the cylinder. I did that and the knob came off of the adapter and I had to use pliers to complete the filling of air to my air rifle. This is a poor design, there should be a set screw on the knob to secure it to the valve shaft so this doesn't happen. I have done exactly that and now the problem is solved. I feel that for the money I spent on this adapter this shouldn't of happened.
