Got bored and built a rifle . A 300aac. The rifle at random , but relatively consistent times will fire 4,5,7 times, then malfunctions. This is the odd part . It's failing to feed, but in inconsistent way. .....
1. Sometimes the round will chamber but not completely. Can usefoward assist to fully sear round
2. Round will chamber , you'll need to apply a lot of force w forward assist to fully seat , think tap with hammer
3 round will get lodged at odd, varying angles going into chamber
4 rounnd appears to be fully seated, squeeze trigger, and click, nothing
None of this ever happens on first or second round. No real pattern to it , other than it's going to happen. Rate of fire makes no difference, fast slow ect .
Ammo brand type ect makes no difference. Magazine type no difference, nor does capacity of said magazine , full , half ect . On occasion, I will find a blown out primer between boldface and fresh round being chambered , but that been rare . Really not even sure where to start diagnosing this problem. Any ideas would be helpful Thanks.
