You better take cover before this thing explodes with a shower of BBs! When fired, it emits a very huge cloud of gas, which is actually the gas that you loaded into the cartridge. It comes out together with a blast of BBs, which is a cool thing if you ask us.
Features:
A combination of Rubber (head) and Metal (base)
High density gas inlet valve
Fits on all 40mm grenade launchers
Package contains 3 pieces of cartridge
Each cartridge contains 12 slots, while each slot can store 10 rounds of 6mm BBs (a total capacity of 120 rounds)
For the price this three-pack is a great value, the polymer "head" does not feel as nice as the metal "heads" you find on more expensive 40mm grenades, but as long as you are not dropping them on hard surfaces they feel like they will last.
Performance-wise, they work about as well as any other shower grenade on the market I have tried.
I did have one of the o-rings that retains the bbs fly off when I shot once, but it was an easy replacement.
The o-ring/replacement part sizes are M1.5x35 (BB Retention o-ring), M1x30.5 (Body o-ring), 1.5x15 (Knocker o-ring), and 4mm ball bearings. The fill valve o-ring looks like it should be the standard 002 size o-ring.
[RedWolf] Hi Erik. Thank you so much for the detailed review!
