I've been looking for a Rock River Arms Predator Pursuit for awhile. I'm not sure what I'll do with it but figured that I needed one anyway. The Obama administration will probably have black guns banned before long so I intensified my search. Walked into my local dealer yesterday and he was just taking a RRA Varmint model w/24" heavy barrel out of the box for display. It wasn't exactly what I wanted but black guns are hard to find and are being scalped all over the place. I had him put it back in the box and I took it home. If I decide to shoot it any time soon, is it necessary to completely disassemble the rifle so that it can be cleaned and lubed before initial firing? I'll probably pick up a few magazines for the RRA. Many different manufacturers make magazines for the ARs and I'm sure that the quality varies. Any suggestions on quality magazines?
