Matrix Full Metal 40mm M203 Airsoft Grenade Launcher for M4/M16 Series Airsoft Rifles (Model: Mini / Black)

"I just got this grenade launcher and it fits very well on my m4 no wobbling so far and looks amazing. The one con I have so far is that I have to pull the almost off to fit in my 40 mike shell and it’s a very tight fit to the point where it took some of the sticker off the shell, I’m sure it fits other smaller shells but just disappointed that it doesn’t really fit the one shell I enjoy using.

"Overall build quality is decent but The ribs inside the barrel make it impossible for the taginn shells to fit. If you’re looking at this to use with taginn shells please do not buy.
