I've found top rail covers near the gas block keep your thumb cool if you use a forward grip. It can get a little warm up there.Not sure if I'm going to keep them in the current configuration/s or not. Particularly the top rails. My kids had fun playing "legos" with them, though.
LOLSO FREAKING AWESOME.... The stove and counter top that is...
I've found the AFG2 works really nicely if you position it forward off the bottom rail, so that it comes even with the end of the gas block. Gives you a little more room to extend your arm out. Just need to be careful not to touch the gas block with your thumb, but that hasn't been a problem for me.Looks good. I'm trying to decide what stuff to put on the forward rails on mine. Leaning towards the AFG2 as well...
