i'm new here and i'm finding alot of great stuff. i've been looking at several different ones. i've looked at the colt A3 elite, shot a colt flatop hbar, looked at a bushmaster varmiter, looked at the armalites, and an olympic. i'm looking for an AR that can serve as a ranch rifle, acurate but can still be tactical. if i understand right, it is ok to own a sound suppressor with the right paper work. that would be a huge benefit as to the fact that i'm around alot of livestock. can a suppersor be mounted on certain barrels? i've been reading some stuff about the different barrels. a low maintenence one would be great. so far i've gathered that chome lined is the way to go. what about stainless? what are the pro's and cons? i would greatly appreaciate any input as im noticing there are alot of people here that know their stuff. thanks
