I think the AR bug bit me again. I'm getting really close to buying another one. I was thinking I wanted a 20" but I think I can use the 16 for everything I want it for, mainly being SD. I wanted a M4 style gun, but now I think I want the Heavy Barr.. My question is, if I never want to put optics on it, why should I buy a removable carry handle model? I can buy a new DPMS fixed handle for 750.00 with 10% off. So under 700.00. A removable model, of the same gun, is a couple hunred more.
