Airsoft Evike.com Polymer Propane Adaptor w/ Integrated Silicone Port for Airsoft Gas Magazines (Package: Adapter + Silicon Oil + BBs)

"The pictures make this thing seem mediocre, I was very skeptical about this purchase. Upon arrival it seems to be great quality and the materials are quality. The silicone is also good quality.

"This is a great thing to have when you decide to start using propane instead of expensive green gas. The only complaint I have isn’t even about this adapter (because it works perfectly as it should) but about how bad propane smells! If you’re lucky and can get green gas locally, just get the green gas. It’s worth not having to smell nasty butt every time you pull the trigger or refill your mag. I love how you can put silicone oil in it efficiently though and I’ve had no leaks or breaks so far. Also if you’ve never used one, attach the adapter to your propane, then unscrew the top part and only put 2-3 drops of silicone oil in, then put the top back on and fill your mag and you’re good to go

"Works fine on my action army mags.

It's cheap & easy to use, doesn't damage your mags

If this device fails or breaks, it's not a huge lost.

Keep buying some extras or spares, it's a great deal breaker.

Mad bull metal adapter need to take some notes from this bad boy.

& yes i own a mad bull & it's not practical what so ever, stay away!.

Buy this these instead.
