The D Boy Full Metal 3in1 M203 Grenade Launcher (Short) is the most well rounded launcher in airsoft. This M203 launcher will mount to any standard 20mm rail, or it can be barrel mounted to real gun style delta ring AEGs and Tokyo Marui style delta ring AEGs. This is possible because D boy provides different mounts with the launcher. Depending on what gun you have you could mount this M203 launcher to any M4/M16 on the market.

Got this for my P90 looks BADASS oh yeah I have the RIS for the gun so yeah. Well been in three battles with it never failed a little long for a CQB weapon but that's ok for me good job with the 3 in 1 thing cause it can be a stand alone launcher, RIS mounted or built in! Great gun add on sums it up grenades are a little expensive though reusable charging CO2 is some times annoying.
3 in 1
very cool looking
realistic(could be pro or con due to length)
Grenades are exspensive$$$
CO2 chargers have to be bought$$$
long buy a grenade launcher that says "short" if you want a CQB style
