HSMITH - Again we agree. I have used NuLine quite a bit , I have use them for
mumbley something years. The word "Old" comes to mind...
Chris - Colonials worked fine in my limited use /testing.
Rest of the folks gave great information.
I'm big on gun fit to shooter , as mentioned above eariler , the off the rack gun just may not fit you. Have someone experienced assist, ESPECIALLY an experience gun smith if LOP, pitch, cast ... or installtion of recoil pad is needed.
Unload Gun - Check Thrice, and any time you set it down - check again.
Close eyes and CORRECTLY mount gun to face 3 times, on the fourth - what do you see? Are you looking down the rib, over the rib , or "back of" receiver?
If you do this in front of a mirror , and the gun fits, your eye will be slightly atop the rear looking straight down the rib.
Sometimes shims b/t stock and receiver will be enough...other times more may be required, pitch, cast ( on or off) LOP, etc...
Good Luck
