Posting this for my son. AO rebarreled and put there magic on this gun a few years back. It has the factory accutrigger in it. Recently the red part of that trigger freezes up and it won't fire. You can kick a round out and put another one in and it works fine. Are these triggers known for this or going bad and is there after market triggers for these rifles? The rifle has around 500 RDS threw it and has never had a hick up. Is it the trigger?
