Yup.  True Story.  Actually, it gets better (for you, worse for me).

Today's Airsoft Question comes from Seamus O'Toole from Blarney, California.

Seamus writes,

"Top of the mornin' to ya, Mr. Harris.  Perhaps you might enlighten me on how to increase the consistency and reliability of getting my Hokkatsu Thunder B Sound Grenades to detonate after I toss 'em into a room I'd like to clear out.  Sometimes when I toss them, they don't explode for one reason or another."

This question could not have come at a more perfect time, considering that I'll be heading out to Operation: Route 66 - The Battle for California tomorrow, where I'll have many opportunities (hopefully) to throw these beautiful Airsoft grenades into dark rooms & corridors filled with lots of Tangos. 

For those of you just checking into Airsoft, Mr. O'Toole is referring to an Airsoft Close Quarter Battle (CQB) scenario where he knows there are some bad guys in a room or building and he'd like to toss his sound grenade into the room to either disorient the OPFOR or obtain a direct kill, depending on the rules of the game.

So anyway, back to those reasons these Thunder B grenades don't always go off.

#1: One common reason is that the striker pin did not sufficiently pierce the Crosman 12 gram CO2 powerlet cartridge inside the core unit.

#2: The other common reason Thunder B's don't go off is due to a poor air seal between the top of the core unit and the disposal shell.

I've personally experienced both of these issues and have witnessed others as well.

The good news is that I've decided to share the solutions with you, rather than leave you to your own devices to try and figure it out.  Turns out, it's not rocket surgery though.
