He should be good as long as he takes the bipod off first. That said, some folks can CCW some supprisingly large weapons. Not a IWB though, and not in the summer. I carry a full size, full weight 1911 with x-mags all day, everyday, everywhere (sheep Dog) . I don't even want to think about for how long, I'm 55 now (good shape though) . Never been a issue. I'm 5'10'' and have a 34 wast, 155 lbs. I hate IWB and will not use one, and its HOT here on the border! I have the authority to open carry if I want - but that's only about 20% of the time and mostly conducting training. There is some skill (how to) required in carrying a weapon either CCW or open regardless of its - or your size. Having someone make your weapon when it should be concealed is at best an embarrassment, and some who CCW can be charged with brandishing under some State's laws. One size does not fit all. Training helps. And yes a "reasonable" sized weapon helps. The key is REASONABLE. But as the man says, observe, orient, decide, act. We all don't live in the same world. We all don't wear the same size pants. Your Boogie man is not my Boogie Man. There was an advertizing campaign out for a while. It said something to the effect that life or death decisions are made at the cash register. I liked that.
