"Got it on the mail last friday, it took 5 days to get here counting thursday(thanksgiving holiday).
This adaptor is got to be the bestone out there, It's made out of stainless steel, with silicon orings. this thing is heviduty man it will never break like the plastic or aluminum ones if you ever drop it. What really makes this propane adapter special is the silicon port, just spray or squeeze a few drops in it and you'r set to go. In the long run it will save you hundreds of bucks in gas for your guns.

The only con is that it does not come with a little bottle of silicon like the plastic one does but sinse silicon can is like 4 bucks it's not really an issue but it will be a +.

"This adapter is Great. I love that it has a silicon port. The whole thing is metal, with some rubber O-rings of course. Easy to install and use. Just screw it on to your propane tank. Unscrew the little metal screw on the side to add some silicon lube, screw it back on, and use it just like you would with a can of green gas. Definitely recommend this, seeing how propane is so much more inexpensive than a can green gas, and when used with silicon, is the same thing as green gas, but with more power.

"Had this adapter for a year and a half then dropped it and the tip popped off. This a great adapter but just make sure you don't drop it.

"the only reason it gets 4 stars is because the other day the propane adapter silicon port when i opened it to release the gas to remove the adapter the adapter had the tank valve pressed in and was stuck pressed in so i lost over 3/4 of a brand new tank of propane but other than that its a good adapter if you don't ever wanna remove it.

"I bought this for my king arms gbb m4. It works very well for my Marui 1911, but the valve on the m4 gbb magazine is slightly larger, so the Madbull adapter does not seat properly around the fill valve and sprays propane everywhere. I thought it was o-ring problems so i bought replacements and have gone through nearly all of them before realizing this nozzle does not fit properly.

"Just awful. Bought it to use with my WE 416 and KWA USP and it's just crap. Would leak out of the sides and would completely freeze over. Buy a plastic propane adapter like the Airsoft Innovations one, much better.

Looks cool.
Madbull (which is usually a good company)

Does not work as should.
Freezes the O-ring and itself.
Does not fill mag.
