"I have just received it in the mail today. This thing looks great right out of the box. It has a solid feel, look, and makes your weapon of choice look beefy and more intimidating.

I test fired it at some cans using Pro-Arms 48 round shell and was happy with the results. Great grenade launcher.

Solid build
Great look
Great feel
3 in 1 for many mounting options

Did not come with instructions... but youtube shows you anything :)

"Overall, this is a great launcher. It fits on a gun and makes cheaters call 'hit', just like it's supposed to. It has a good weight to it, and everything is sturdy.

- Launchers a lot of beebees at once when needed.
- Can be attached to anything with a barrel or RIS (this is a generalization)

Was skeptical about the barrel not being metal but I have came to enjoy the light weight. The barrel is made out of very strong material and I don't see it breaking on me.

"Overall a well-built airsoft launcher!
Everything is nice and solid with very little wobble, and the included adapters will bolt this to ANYTHING.

I personally have attached this model to the lower RIS rail on my G&G CQB_R Blowback M4.
The fit is very tight and the launcher barrel is similar in length to the rifle's "silencer"

Fits almost all barrel types
RIS adapter for generic mounting
Solid feel and construction
Very efficient "spent shell" retractor

Matrix "Speed" M203 Grenade Launcher for M4 M16 Series Airsoft Rifles (Model: Long Type / Desert)

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.
