That's pretty funny. I have a blackhawk serpa for my meu and I've never had anything like that happen to mine.
But have you filled yours with sand before, ross?
No I have not, Dave...Llyod...Richard or whatever you are calling yourself now. But I have had mine for a couple years now and I have not had any problem like that with it before...
Sand, mud, pebbles, grass, silt, blood, body tissue; Seriously....
Dirt is a huge concern figuring in combat being on your belly is one of the prefered positions.
