Hey everyone, i'm thinking about getting an Olympic Arms AR-15, good choice bad choice? i dont want to spend 1000$ on a bushmaster quite yet, and OA has a 560$ model do you think its that bad a gun? will it have conisistant groupings at 100 yards? can i get a 26" bbl for it? Or, do you think i should save up for a better AR-15? thanks alot, in advance.
