A tip of my cap to you, Airsoft Manufacturers.

The following is a list of airsoft manufacturers, brands, companies, etc. You'll notice there may be companies listed that are technically making products geared for real world law-enforcement/military/governmental use. However, as most of you know, there is a lot of crossover between those markets and our glorious market of airsoft. In some cases, the real world stuff actually makes for the best airsoft stuff as well when it comes to things like tactical vests, pouches and other gear, for example, because they are designed to withstand a high level of wear, tear, and otherwise abusive conditions. Only down side is a lot of time the real world stuff is a lot more costly than the airsoft knock-off versions that may be available. Anyway, if a company's products can be used in airsoft, I'm going to list it here.
