ok a couple of questions, i got a cmag, it came with all the stuff you need, but no manual, so  does anyone have a link to the manual or can you tell me what i do with the graphite lube? im also wondering if i can keep it loaded or if it must be stored empty.

will i melt my lmt 10.5 upper's gas tube if i do a mag dump??

thanks

You can store it loaded.
Chuff a little graphite directly on the dummy rounds and shake it around to lube - less is more

I've never melted a gas tube from a beta dump, even when firing as one long 100rd burst, although I more commonly go in 4-6rd bursts (approved lmg/gpmg supporting-fire style).  

For what it's worth, I've also done back-to-back beta dumps during mad-minute firepower demos, on my Bushy chome-lined 1x9 "A2" profile barrel without blowing the gas tube.  You COULD see it glowing orange through the vent holes on the handguard, in the smoky evening twilight.

ETA docs link:

Beta's got online docs here http://www.betaco.com/pdetails.asp that you can print out.  You could probably also call them and have them mail you a manual.

I've kept my C-Mag fully loaded for weeks at a time.  Never had a problem with it feeding.  Just don't drop it!


When I do a Full Auto Shoot one of the most fun things is to do a Mag Dump. It heats everything up horribly, but it's so much fun!  As a general rule I don't reload my C-Mag after I empty it.  The temptation to do another Mag Dump is just too great.

Always kept mine loaded, and no way you should melt your tube from one dumb.
