"These are fantastic. Buy these. Don't buy King Arms' 120rd ones.
I've owned all the different 40mm grenade brands from Madbull to Craft Apple Works and I must say King Arms did something right with these 84rd ones. I use them much more often than I thought I would because they pack quite a punch. This is because they are direct copies of the Mosquito Molds grenades by CAW. King Arms emulated their internal design which requires more gas, but sends BBs out with much more force.
Highly reccomended. If Evike re-stocks at some point. Definitely invest in these.

"this is epic it creates a shower that will destroy any enemy behind a tree or burm. I used these in a cqb field and I shot someone at close range.

"These grenades are outstanding. They shoot hard, have a good spread, and are easy to load, even if time consuming. What other people have said about SLIGHTLY unscrewing the top is true, and makes it much easier to reset the grenades.

All of that said, i would recommend the grenades. I bought two packs of them to load my ICS 190 MGL and have been overall satisfied with the product. I have no regrets on buying them. Also, i use propane in mine and to me it seems like it works much better than green gas.

"Just got these in Oct 2010. Latest version seems great.
To reset push the button on the bottom until it comes all the way out. Sometimes a 1/8th turn ccw obn the bottom helps, then retighten. DO NOT take it apart. Period. You will loose the Ball bearings, this is true of most grenades.

Shoots a nice shower of BBs. Range is 50-75 feet. Need to arc the shot a bit for long shots. From the Vids I have watched, the Madbulls will give you much better range... You get what you pay for. But for a closer range blast these are sweet. Nice Boom upon Launch with a puff of smoke from the Gas, sweet.

These use Green Gas, reset grenade, load gas in top nozzle.
BBs go in the holes. I use my unjamming rod from one of my guns to push them down. I speed loader in to the holes, pack in with the rod. Turn upside down and catch the extras in my hand.

I use these in a DBOYs 3 in 1 launcher attached to my G&G raider blowback.
So far zero problems after quite a few rounds over the 1st Week.

"will this fit the m203 echo1 grenade launcher?

Webmaster: All King Arms grenade shells are "Standard 40mm Airsoft Size". All grenade launchers (Echo1, CAQ, STAR, G&P, Matrix, Classic Army) on Evike.com are "Standard 40mm Airsoft Grenade Launchers" unless otherwise specified. So yes, they are all compatible.

"To answer all your questions yes it uses green gas, to put in the gas you put in the nosel in the hole in the middle of the grenade for three to four seconds , to load it you use a loading road and push bb's into the holes around the rim. Highly suggest this because its powerfull and doesn't waste too many bb's.

"These are 40mm grenade shells. It is the standard size for Airsoft grenade launchers. 99% of the grenade launchers thats gas powered use these shell. (Unless you buy from some random websites that carry the weird size stuff, which will be a waste of money to buy.) Evike.com keeps pretty standard on the guns and upgrade parts they offer, good job for setting the standard evike.com!! Making our lives easier!

"The difference between the Blue and the Red one from King Arms. (Compare the 60rd to 60rd and 120 to 120 rd) is:


1) Color
2) Shape / look


Thats it! Info from King Arms.
by Michael K. on 07/11/2008
"Yes, this grenade takes gas like all Mad bull, Craft Apple Work, and other airsoft grenades for M203. Pretty decent price for a set of 3.

A tip for all grenade users, if you don't know what you are doing, don't ever twist it open.

"Works well enough.

Pros:
Good secure seal/gas intake.
Good quality construction.
Fairly affordable.

Cons:
Ball bearings are very loose (don't open it if you don't have to, because the bearings aren't held in by anything more than a gob of grease. Definitely don't open it outside in the grass, you will lose you're bearings for sure! )
