I have a 77mkII sporter in .308. I recently changed from the factory laminate stock to a factory new synthetic stock. Now the gun WILL NOT FEED! It wond feed at all! When you put more than one round in the magazine, the follower either jams down and doesnt push up, or cocks to the side and lets the rounds fall under it. The stock fit was very tight, but it went in ok and looks to have a real nice fit, but i cant for the life of me figure out this feeding problem. The folower and or spring is not backwards or anything. Should i send this in to ruger? I purchased the synthetic stock from them and with their recomendation.
