Using my snap-on cover with stock factory peep sight produces 2"-3" groups at 100yds. Sure is a pretty gun in .308, though, and kinda rare now. Probably do better throwing rocks at the target.
I always wanted to scope my Garand 30-06. B-Square made a side mount, but I was forced to sell that rifle years ago. The fella in Wyoming who bought it said it was the finest Blue Sky Garand (reimported from Korea) he'd ever seen, and he collected Garands. It had a brand-spanking new Winchester bbl. and a used WRA trigger group. The receiver was Springfield. I refinished the stock, added an original stacking swivel, and thought that was one gorgeous rifle with a helluva lot of history behind it.
