Surgeon 591 recoil lug fitment into an AICS

[C Ward]

Open the front , towards the barrel channel , of the pocket . Must be an older stock they changed the pocket size so you didn't have to do this anymore a while back .

On all rifles the recoil lug should have full contact on the back , towards the trigger , and in a perfect world thats the only contact with the stock . If it touches on the front , sides , and bottom it it not the end of the world as long as it's not binding , and consistent contact . The AICS chassis react well to being skim bedded .
