Re: RRA predator pursuit or varmint?
I can't speak for the Predator Pursuit but I can for the RRA A4 Varmint 20" that I use for coyotes and sometimes on woodchucks. Mine is the A4 upper matched to an A2 lower from 2008.
If you want an AR that is extremely accurate (by AR standards) you'll certainly be pleased if your gun is anything like mine. It IS a very muzzle heavy gun but since I almost always shoot from some kind of rest (bags, pack, bipod, rolled up jacket, ect.) the weight isn't much of a problem. I had a Bushnell Elite3200 10X scope on top for a while and it was adequate for my hunting out to 400yds or so; I don't get to do much hunting in beyond that distance. I have shot at steel beyond that and one would think the targets were from a bolt gun.
If I have a complaint about my ARs, it isn't with the rifles but the quality of the magazines. The gun is really good. If I miss, it is because I missed - not the gun.
