I bought some of the LEO mags from FourFourMag. They should be here Monday. I still have 10 preban 20 round mags in blister packs, and I broke out two of them today when I went to the range. I took my preban Ranch Rifle. I recently put on a John Masen Muzzlebrake/flashhider, and a recoil pad to extend the trigger pull. Both seem to be good additions. At 100 yards today, shooting from both sitting and kneeling positions, I was able to group three shots into 1 1/2 inch. This is about one inch better than I have been doing with this rifle. I do use a scope on this rifle, a old 2 X 7 Redfield FiveStar 20mm tube.
I have other .223 rifles, and took a Bushmaster and an Armalite today also, but I still like that Ruger a lot.
