I have a standard synthetic mini 14. This is my first rifle and I got this in March of 2002. One day I just decided I want to get into shooting, and thats exactly what I did. I have been screwing around at the range at 50 and 100 yards. I live in California and its illegal to have a muzzle brake, although i could do something under the table =). I would measure my best by hitting a 5 1/2 inch circle at 100 yards, 14 out of 20 times. Currently I am using Wolf 55gr 223 ammo. I got a deal on it, like 1000 rounds for 130 bucks. I am thinking about changing my rear sight, as its the standard factory issue and it looks like someone took a needle and poked a hole through some plastic. Any suggestions? I looked at www.aosightsystems.com and took a look around their sight packages, anyone have any experience with these?:ar15: I would say the grouping is about 5 inches, but it could just be my shooting fundamentals that need to be worked on. Any other thoughts of tightening up that group?
