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

"It's basically green gas without the labels

Pros:
Cheaper than "fancy" green gas
Easy
Efficient and durable
Propane costs like $3, compared to a small bottle of green gas that is over $15
Propane n solid metal can instead of thin aluminum, so much safer

Cons:
Might smell, but hey, it's propane.
You haven't put it in your cart yet!

"its a must buy!!! very inexpensive and high quality, it pays for its self and works great on gas guzzlers

"I love this adapter! it does exactly what it's made for. 5/5 stars!

"it works fine. I also have the AI plastic, that works great too. Unless you totally scratch up or deform your adapter, or drop it or whatever, this should work fine. Yes it's metal, but it's machined and polished. If you can't get this to work, have someone experienced train you. Or stick with electrics and springers.

"I have purchased 3 of these over time and they are amazing.
1st one: Lost at field
2nd one: Propane tank dropped of top shelf and bent tip off
3rd one: still going strong

Pros:
Plastic is better than metal because metal-on-metal can damage the nozzle.
Cheap
Comes with oil
COMES WITH A (134a) DUSTER GAS ADAPTER!!! :DDDDD
Nozzle has a tab to see if your propane tank has a broken O-ring
you can use the duster adapter to fix your nozzle if it breaks

Cons:
None!

Overall: BUY THIS THING. Ive bought 3!!

"Im an Experienced Gas Gun User and this has been the best Adapter ive come across so far. Does not destroy your o ring seals and does not spray much gas out when finishing up a fill. The actual tip can get chewed uo i bit if you dont take care. Just dont beat on it it and it will last you. Having the oil is a plus too.

"I bought this for use w/ Coleman Propane (from WalMart) in my HFC Full Metal Full Auto M190 & it works wonderfully! No complaints. Recommend.

"I have owned mine for nearly a year and mine is as good as the day i bought it no problems it saves me so much money just like anything else you have to take care of it

"Awesome Propane Adapter

I own the madbull metal one and this one is 10 times better, easier, and does not leak.

Mine came with the bottle of silicone oil. Two drops for every 4 - 8 magazines

10/10 If you need a propane adapter GET THIS ONE!!!

"I got this adapter from my local airsoft shop today. Along with a WE 1911 my I bought from my friend. I used the rest of my green gas can testing the gun out and was disappointed with the low fps. I decided to use the propane next and noticed a dramatic increase in fps. Also I was able to fire more shots with propane than green gas. This adapter costs as much as a can of green gas and it pays for itself over the course of about a week. But as I'm sure you have all heard before, propane smells horrible and don't fill inside. Only outside. Overall, great buy and I completely recommend it.

Pros
Light weight
simple design
comes with a cap
does not scratch your gas valve (but it's plastic)
Sturdy plastic

Cons
.....Have not found any yet.

If you have a gas gun you need a propane adapter. It saves so much money.

"Best adapter ever!!! Vary strong plastic, and will not brake. I would recommed this.

"I've had this propane adapter for a few months now and I must say that it's worth every penny! It's simply a must-have for every gas gun user, not to mention how effective and economical it is; it literally pays for itself overtime since propane canisters are so affordable compared to green gas. Just remember to take the adapter off and spray some silicone lube inside [from the threaded end - not the pointed nozzle] after every few mags or so to help keep your gas guns in top shape.

Of course, being made out of plastic, it's not indestructible either. Don't assume that it'll survive a drop when installed onto a propane canister. A friend of mine dun goofed and dropped the darn thing onto the pavement while trying to balance it on another (blindfolded) friend and snapped the nozzle end right off! Then again, I don't think even metal ones would be usable after that... Keeping the protective cover on when transporting it is always a good idea.

All in all, I STRONGLY recommend this product. Treat it well and it will most certainly treat you well in return. GOOD JOB!

"A simple product. Works phenomenally. The odor of propane is a little off-putting but performance and cost effectiveness are grand. Rigid plastic. Durable build. Good quality. Flamboyant color.
Worth every penny.

"GOOD NEWS! I just saved a bunch of money on my car insurance by switching to PROPANE! no seriously, in the long run, this will save you tons of money. Propane does smell bad, but then again all i'm using it for is grenades so i rarely use them.

BUY IT

"it seems like it would be annoying to carry around a big propane tank isnt it?

The propane tank is not larger than a can of gas...(Don't buy the HUGE cans, get the portable size)
