Im new to the forum so I hope I don't sound too ignorant. I have a national match M1A that Ive put around 200 rounds through. Out of those 200 rounds there have been at least 4 slam fire incidences. I've used three different types of ammo, and tried to make sure I wasn't bump firing the trigger. Honestly I wonder if I made the right decision sinking that much money in a rifle that may or may not be reliable. Some help and suggestions would be greatly appreciated.
