You could just change the grip to a real wooden one and remove the lead weights that are usually inside.
YOu could buy the ones for like $15 off of ebairsoft or something. They are compatible but not the best for getting a lot of rounds down. In Ireland where it is cold enough I would only get off maybe 15 rounds on a warm day, however I occasionally get off a full mag. They are funny like that.fuzzywolly said:The TM's take propane like Grass said, and so far after a few months use, no signs of wear and tear.
As for where to buy the mags, I have yet to find any in stock in the states, and am currently trying to snag one in the local commerce section of the forums. I got two with my MEU originally, but could use a third.
