M4 RIS
The M4 Carbine is one of the most popular rifle models available in airsoft. They are modeled after the carbine variant of the AR-15 rifle. The M4 has been adopted for standard use by many military and law enforcement branches all over the planet. One huge advantage with the M4 platform is the modularity of its design, as many of the M4's available for airsoft are capable of mounting flashlights, lasers, optics, and other tactical accessories. Another great thing about the M4 is the plethora of parts available, both for upgrades and for repair. No matter what occurs to your gun, or what sort of upgrade you're interested in, there will more than likely be a part out there available for you.

Featured here are M4-A1's with RIS (Rail Interface System) units pre-installed for the customer. The RIS unit is the key part that allows for the installation of tactical accessories.
