So I got this Propane adapter thinking that it was just the adapter, but then I realized that it comes with silicon oil, an adapter for air duster, and a integrated gas checker thing. Huge plus. I used it today at an event in my area and it worked great. All I had to do was drop a couple of drops of silicon oil into my propane, screw the adapter on, and I was ready to go. My pistol mags worked great using this, and it was really easy to fill my mags. It's also a lot more durable than I expected: I had it in my backpack with gas, BB's, water, etc, and while i expected it to break or get crushed, it withstood a long day of play on the field.
The Pros of this Adapter Kit are as follows:
Comes with silicon oil, a cover for the adapter tip, and a replacement tip.
Makes it so you can use propane instead of green gas (I can find propane way easier than Green gas)
There aren't really that many cons of this, but here's what I noticed:
It leaked just barely while it was on my propane canister
The box it comes in kinda got smashed
The extra tip seems easy to lose
