Is monster Airsoft a good legit place to buy airsofts?
I would check ShortyUSA.com first.
You must first have a tuner monster and another monster present on the field, The level of those monsters must be equal to the level of the synchro monster you are attempting to summon. Next you place the two monsters from your field into the graveyard then place the synchro monster on the field. This is considered a synchro summon.
Green gas is required for Gas airsoft guns to work. Usually when you purchase airsoft guns, it will state whether or not the gun is a Spring loaded, CO2 Gas, Green Gas, Or Electric (AEG) Rifle. Best place to go for airsoft guns is Airsplat.com. That's where I go for all my purchases and I've had nothing but great experiences there with reliable products.
No. Nothing firing a projectile is legal on a commercial airline. But if you are talking about mailing an airsoft gun to some place in the US, then yes, as long as there are now people on the commercial airplane.
