It's a Eagle lower with DPMS LPK and an ArmaLite upper assy.
Anyway. I chambered a Winchester (55gr FMJ) round, took aim and CLICK
. Nothing. Ejected and chambered another. Same thing
. Tried five or six more times with the same result
. Upon inspection, I noted the primers had a small dimple. Upon further inspection, I noted the dimple was not due to chambering. I pulled the carrier and could move the f/p moving freely. Closed it all up and tried again. Same result
. After considering going to the house, I tried some Remmy ammo which I had in another mag. Perfect function for all 20 Remmy rounds. Then I once again tried (previously unchambered) Winny ammo. Perfect function. I fired the rest of the win. In total I fired 20 Rem then 40 Win. with no problems after the initial smeg-up. I'm scratching my head. Does anyone know what in the smeg happened?????
