The "Speed" M203 comes with 2 attachment kits to mount on all 20mm / picatinny rails for quick attachment / detachment or barrel for those looking for a more compact fitting!
The Matrix "SPEED" series M203 Launcher retailed all the features you will come to expect from an Airsoft m203 launcher but with drastically decreased weight utilizing high strength molded polymer material while providing battle-ready durability. Every "Speed" M203 is completed with 3 sets of mounts to ensure the highest versatility of fitting on 99% of the rifles in the market.
The M203 grenade launcher is one of the most effective and devastating tools in the Airsofts arsenal. Capable of using a wide variety of shells the M203 launcher can shoot anything from BB's and paintballs to foam rockets and Nerf footballs. Generally these underslung launchers add an immense amount of weight to your weapon of choice and make it unwieldy and a challenge to maneuver with. However now with the S&T polymer M203 launcher, you can enjoy all of the benefits of adding a M203 launcher to your build without adding a ton of weight to your front end. Built from durable injection molded polymer, the S&T polymer M203 is as durable and reliable as its metal alloy compatriot and offers the same level of reliability and performance at half the weight. Capable of being mounted directly to most popular M4/M16 Airsoft outer barrels the S&T polymer M203 can also mount to most 20mm accessory rails with the included 20mm RIS adapter, making this M203 a truly versatile piece of equipment to add to your arsenal.

"overall a great addon piece to anyone's primary. it takes all 40m grenades and works exceptionally well. the only thing i should say that is worth noting is to not get the long version and get the short version because its already kinda long (depending on your rifle). also when ever i fire it the orange barrel piece flies off it. none the less it still works. good buy for CQB builds

"Great grenade launcher. I love the light weight. Served me well with my king arms m16a3. Recently I upgraded to a KWA VM4A1 with a quad rail system, and I swapped out the mount. I love this feature. I can use it with pretty much any gun with a rail, or any m4 without. Great buy

"Got the m203 long it fits amazing with my apex MK4 rifle love the light weight it fits 40mm shells snug and I would recommend this to anyone who loves running a m203 but hates the weight don't get me wrong it still adds some weight but not as much as a metal m203

Well made
Three types of attachments for different types of rifles ( ris rails under barrel etc)
Light weight

Don't come with shells
Orange tip(but is easy to remove)
You don't have one if you like m203
