I have an FCP-K in .223. I am the second owner, but it only has about 60 rounds total. When shooting this weekend I encountered an intermittent issue where the trigger and safety would both be locked up. Couldn't pull the trigger, or put the rifle on safe. By cycling the bolt handle up/down (without extracting the bullet) it would work fine. It shoots great(5/8" groups at 100m with federal vital shock nosler ammo). I have had the stock off, but did not adjust anything other than verify the stock was properly installed and torqued. Any ideas? I should note that it is both accutrigger and accustock.
