This firearms forum and people have helped me out greatly in putting together a gun. I finally got the parts needed and put together. I fired it once and it cycled a bullet. Its been leaning against the wall ever since. I've just got so sick of hearing about guns in the news and everywhere, I had to take a break from this for a while. Finding and paying for the parts needed at the worst time just added to the headache. Anyway what I have is mostly rock river. It has a 20" varmint barrel (RRA #0550). I need to do something about a scope. I find an ar awkward for me to rest side of my face against while aiming. I'm thinking though I want the scope as low as possible. I bought some cheap weaver mounts, set my .22 scpoe on it. I think I want it lower yet. I'm looking for a reccomendation on some very low profile mounts, and a scope. I don't know much about scopes. I've seen ones that have extra lines under and to the side of where crosshairs intersect for bullet drop and windage. I think I might like that. As far as ammo, the best stuff I have is american eagle .223 and some 5.56 xm855L. We have a bunch of squirrels, the farthest they range from house is about 400 yards. I don't know what this gun is capable of accuracy wise at what distances. I don't want to overpay, but don't want to buy something that the gun will outshoot. So I'd appreciate anyones suggestions on this. Also a guy I was working w/ told me he has a scope on his bushmaster, w/ iron sights mounted to the side of his rails. He can twist the gun at a 45 degree angle and use his iron sights. That sounds real nice to me. Does that work as good as it sounds? My other question may sound very nieve, but its about cleaning. I've looked all over for a .223 bore brush. Haven't seen any in stores. It seems a .22 brush would be just fine. I mean theres just .0003 in bore dia, right? Well if a .22 bore brush is meant for a .223, why doesn't the manufacturer print 223 and .22 on the package it comes in? I did see some 223 brushes on ebay, the had a set of large bristles on it also, I think for cleaning the inside of the bullet shell housing or something. I'm not sure how'd you ever run the thing through a barrel though. I've read all this stuff about bore snakes and scarring your barrel w/ the aluminum cleaning rod. I'm really confused about this. I mean, your firing slugs from an explosive charge through this barrel, how is an aluminum rod going to harm or damage the gun? Also I've stood and looked at bore snakes in the store. It seems that shrapnell would become embedded in the cord, and using it repeatedly on your gun, you'd dragging the stuff you just cleaned out back through the gun. Am I right, or am I missing something here. Anyone know of a good video or explanation on this. Any suggestions on these questions would be appreciated.
