Hey guys, been browseing the forum for a while and decided to sign up. Im looking into my first AR-15 and have to say it seems like wanting an AR is an addiction so i cant wait to get one and start shooting. Im into varmit hunting mostly and occasional targeting for fun so i want to go with either a 20" or 24" barrel, as i will be set up waiting and the extra bulk and weight wont be an issue for me. I decided to go with Colt and my question is about Colt having two web sites with their AR-15s'. One seems to be geared towards military/law enforcement use (LE) which all have 16" or shorter barrels and their regular site has models geared towards competition/target rifles (MT) and these have longer barrels. Are these two different breeds? I know a little about the Mil Spec stuff and was curious if the models with the longer barrels are of the same quality control and internal parts. Thanks.
