Acetech 40mm "AceHive" Airsoft Gas Grenade Shell (Model: Single Shell)

"Bought the smash pack off a different site and I have to say that these are the best shower grenades I’ve ever used in airsoft. They’re easy and fast to reload, consistently fire, and hit decently hard, but not to the point where it’ll hurt somebody (I’ve bought shower grenades where you shoot 50+ BBs at someone and they can hardly feel it). I’ve had them for over a year and still haven’t had to change the o rings out. I’d recommend to anybody who wants to try out shower grenades.

"Amazing! These grenades self reset when you put green gas in them, and the speed loader, or spawner, loads it super fast. I have yet to try these with CO2, as I only have one launcher capable of firing grenades with CO2 in it. But, I don't need nor want it that way. I would suggest buying these even though they are on the high side as far as price is concerned, the speed of setting these up is worth it. Just a tip though, don't push the center button in too far and give the grenade a shake while loading to make sure the bbs fully fall through to get a nice even load. Oh, and don't forget to lift the oring in the middle by pressing the center button first too, it moves up a little but not all the way when you fire it!

"Loud, easy to use, and works well. The one issue I had was that the firing primer would get stuck depressed after firing. I added a little silicone and it works flawlessly. Would recommend.

"Fantastic Grenades, Easy to use, effective spread, and Loud, definitely have the intimidation factor going.
The other thing you can't beat is ACEtech's warranty department, who helped me through the warranty process, and overnighted me a new set when it was discovered that mine had a defect.
I recommend them to anyone and everyone I can
