Took my new Springfield Scout to the range today for its first firing. Have the gun in a JAE stock with a Sadlak Airborne scope mount. Problem I am having is the cases are stove piping like a 45 auto 1911, but the case stove pips to the side. Tried 3 different mags and it consistently happen 3-4 times per mag. Tried FGMM 168's and 147 Ball, no difference. Brass marks on the top of the scope mount at the very front and on the receiver at about 1 o clock. When it happens a round chambers in the barrel, a empty case is stove piped, and if you actuate the charge handle you now pick up another round making for a stoppage that requires you dropping the mag to clear. This is not my first gun of this type, but the first time I have run a optic on a m14 type gun. Any ideas would be appericated.
