saym14 Posted November 4, 2010 Share Posted November 4, 2010 I heard rumors they can direct hot gas to your hand ? also do the aluminum forearms heat up more than the plastic ? Quote Link to comment Share on other sites More sharing options...
Jackalope33B Posted November 4, 2010 Share Posted November 4, 2010 Never had any gas hit my hand from the KZ rail. Yes, the rails will heat up.......... If you leave your M4 in the sun for a few hours But heating up from firing the M4, Ive never had that problem.. Quote Link to comment Share on other sites More sharing options...
