What are the differences between CAR and M4 uppers? I haven't been able to really find this info here or on ar15.com. Is it just the different type of handguard? I am buying an upper kit soon and would like to know the difference. The Model1Sales kit for the M4 is $40 more than the CAR - why?
Just to clarify...I know the military M4 has the shorter barrel, I'm talking about the civilian 16" barrel. Thanks.
Thanks.
