I've got the Olympic service match version, and I really like it. It has a 1:8 heavy match barrel, two stage trigger, and match sights -- so you are looking at a very different rifle.
Two raps on Oly:
1) Their stainless match barrels have really tight chambers - contributes to accuracy, but may cause feeding problems with random mil-surp ammo. My rifle has been 100% reliable with hand loaded match ammo, but that's all I've ever shot in it.
2) The finish is not as durable as some other AR's. Then again, mine is a match gun and doesn't get beat around too much.
I've been very happy with my Oly - up to you to figure out whether the one you're looking at meets your needs.
