Madbull "King Grenade" 204rd Extended Length Airsoft 40mm Grenade Shell (Model: High Power)

"This grenade is the best for clearing rooms. With the CO2 adapter it'll shoot .2g bb's and easily hit a target at 100 feet if there's no overhead cover. If you wan't an advantage, buy atleast one of these shells and the portable co2 adapter too.

I did have a few problems with the shells and I'd recommend filling it with under 750 PSI with co2 and Propane works great too just don't use Green Gas. The heavier bbs you use the more dense the spread is, and the shell shoots the farther depending on the length of your barrel. Buy it and extra bearings.

"This thing is a superbeast its amazing! I use Red W/E gas and i love that poof sound. Yes it is long 5 1/2 inches but workable with most grenade launchers. Little food for thought try experimenting with the payload try 150, 160, 180 and see what you get. Your scatter depends on weight of bbs, personally i use .25s

Pros:
MASSIVE capacity
Durable
Invokes fear

Cons:
Long time to load
Heavier than most 40mm grenades

"This is one awesome grenade shell. Well built, easy to use and powerful. I do not recommend putting in 204 bb's as this will greatly reduce the effective range; however, 90-140 bb's will create a very large pattern and take out anyone 70ft away and 30ft wide pattern. This thing is a BEAST!!
