Question: what else would i need to purchase with this item?is there certain nozzzles needed to fill a gun,specifically a revolver.
Document: Great Purchase! Easily connected to the gun and boom,boom,boom. Was able to use the gun all day. Very happy with this purchase. Thank you.
it sends the cans, but no adapters or anything to be able to fill up the airsoft gun my 16yr old has.
It's exactly what it is: green gas. It works with my KJW M700 Take Down, my KJW M9A1 Tac-Master, my friend's KWA H&K MP7, and my friend's TSD/HFC M9. I like that you get two 1000mL cans, which is a RIDICULOUS amount; we still haven't finished one can! One thing about this can is that it is convenient. I can carry it in battle in case I ever need to fill up.
This gas is VERY cheap gas. It is not green gas. When you get the item take off the papers and everything. You will find a different company logo than the one pictured. [...]Also, this Airsplat green gas doesn't lubricate the gun.
The gas is not really green, but it works well as a propellant in my WE M1911 Blow Back Air Soft Gun. The canister loads gas like a butane lighter refill cartridge does. The fill valve on the Green Gas container must be perpendicular to the fill valve on the gun magazine for best results. Two seconds of fill time and your good to go. The gas (propane and silicone oil) is rather pricey, though.
I'm new to Airsoft (toy guns that shoot plastic bbs), found an ICS M203 Airsoft Grenade Launcher on craigslist and thought it'd be fun. Purchased this green gas along with an 18 round 'shower' grenade (works like a shot gun - my first and only green gas device). The green gas works great - has a metal tip to fill grenade (or other device). Used it plenty of times and haven't had any problems.
good brand it gives the power i need, i will not use other than this brand, and it is easy to use
Exactly what I needed for a great price. Ordered 2 sets of 2 and got them. Will order from this vendor again.
Works like I expected it should. I have had no problems with its use. Will purchase again in the future.
we couldn't figure out why the green gas wasn't filling up our riffle...the nozzle wasn't long enough...frustrating!!! now we need to buy an extention
Answer: yes
