Air Venturi Tank With Stock & Adapter, 13 cu in, Aluminum, 3,000 psi, Black

It's nice to be able to convert a 90gram CO2 and you certainly can save money filing your own tanks.

The o-rings! The o-rings in these tanks are garbage. I have three tanks, two AV and one Sig (it's the exact same tank), and the o-rings on the fill valves disintegrated after just six or seven months...on all three tanks. And why do these cost twice as much as paintball tanks?

Good luck finding replacement o-rings. Pyramyd Air has a repair kit with replacement parts, but it's too expensive, especially if the o-rings aren't any better. Oh yeah, don't try buying paintball tank parts for the AV or Sig tanks; they don't work. The threads are different.

Air volume capacity, regulated, easy to fill and gauge makes it all work.

Length of bottle should be shortened. Shoulder plate needs redesign, the 90 degree angle should be 75-80 degree angle.

This system took a co2 working Sig MCX air rifle and caused a major leak which resulted in complete malfunction of the rifle. The tank itself came apart after a few days and everything was returned. Unfortunately my Sig Sauer MCX was permanently damaged and trashed without any retribution.

I really like this air tank system. It'll save money on Co2 bottles and allows for considerably more shots per fill. The cost will quickly be covered in savings from not having to buy cylinders. The system is very well built, I fell very comfortable filling the tank with 3,000 lbs of air. And just a side note, I found an outfit that sells bu*+ stocks that fit on the 2" tanks perfectly. They have several models in multiple colors. I put a tan one on my Sig MCX and a black one on my Sig MPX. Very pleased, thanks you so much.

Nothing I can think of. Seems like it's made about as well as it can be. The quality is superb and the design is pretty much as good as it could be.

Hope this is ok, here is a link to the outfit with the bu+* stocks.

Nothing! This is a waste of time and money, and for $100 is an absolute joke! Won't hold air at all, fill it up to 3000 psi, it's empty in no time. Worthless piece of junk!

You might as well save the paper they put in the box for shipping....it will hold air as well as this does.

Don't buy it, you're wasting your $100 on a piece of junk.

Pretty much everything except the fact that I don't know how to fill it so it's just collecting dust .

Should come with it's own handpump.

Due to a defect in the product I was unable to try it out. So returned it. Also it is hard to get one of these in my area.

Check the item you are sending before mailing it.

More good guns are comeing on the market every day that require the 88 and 90 refill tubes.

Ability to shoot up to 5 30 round clips before reloading my Sig Sauer MCX and MPX.

A cover to match my MCX and MPX.

If you're using a pump, at least 150-200 pumps from empty to 3000psi.

I watched the video made by PA. It is a fabulous alternative for the 90g canisters.

A little too long compared to the original gunstock

It's nice using compressed air versus co2 cartridge. Unlike co2, shooting with compressed air let's you fire shots repeatedly without freezing your gun up and losing power Unlike co2, you can shoot repeatedly without freezing up your gun and losing a bunch of power.

When replacing the buttock with the adapter piece, tank and shoulder stock piece it adds an additional 5 inches from the original. Making it quite awkward to hold and get into the right position when aiming. I'm 6ft. 2" with a decent arm reach and it still feels unconforatably awkward to hold. Feels way too far from your body.

The extra length when replacing the original butt stock with the tank kinda ruins it for me. Way too long. If your deciding to purchase this just take a block of wood that about 5inches long and put it between the butt stock and your shoulder. That's where you gun will rest when using the tank. Sorry but I give it 2 thumbs down.

Refillable and a portable

Make it a little bit shorter so the concept of MPX wont disappear.

Im happy to have it I will buy it again
