Yep, falfiles is where I did a lot of reading before I made my purchase. The only thing I did was take the rifle apart a few times to learn the various components and how to properly clean them. I played around a little with the gas port, but ended up putting it right back where the factory had it set.
Have you shot it yet? I was surprised how easy it was to zero the rifle. In fact, very little adjustment was needed from the factory settings.
There really aren't any special tricks. I will say that if you're gonna scope it go with the DSA scope mount. From all my research it appears the most stable platform for a scope.
The only problem I had was the front screw that holds on the handguards shot loose. My fault though since I didn't tighten it good after taking the rifle apart.
In the first few rounds (if you recall, since you were with me) I had a few failures to eject. But that was due to my playing around with the gas port before I even shot the rifle.
(Are you seeing a trend here? Seems like the few problems are ME!
