Bolt was fine until I took it apart. It shot fine before( when i was testing it after purchase even after 30 -40 rounds)Put it back together after getting bolt bent. When to a range it was shooting fine and then started to get really sticky. To a point where I couldnt even open it without manually cocking it. Came home to clean and I hear grinding sound took bolt apart and there are grains of sand in a bolt. ***. Cleaned it put it back together and it's still sticky. Once I close the bolt and dry fire it... That's when it sticks. If I just close it and open it it's absolutely fine. Can some one help?
