Hey guys, I am having an issue with my rifle.
Ruger American Predator in 6.5 Creedmoor.
When I purchased the rifle, I immediately changed it to the Magpul American hunter. Rifle shot great. Maybe 50 rounds? I decided to swap out the muzzle device. Removed the rifle from the Magpul Hunter Stock. Changed the muzzle device. Installed the rifle back into the stock. Now the rifle will not feed from the mag. If I add tension by pulling the mag down without pressing the mag release, it works fine. What could be the problem?
