light primer strikes on my 6.8SPC...

[shooter_from_show-me]

What would cause this. Went out to the range today with my AR 15 and a Marlin 336 in .35 Rem, btw this happened on th AR. Got off 3 rounds and then "click", I waited 10 seconds before ejecting that round. Then chambered another round again "click". Then I tried a different box of ammo same thing . BTW I am using Silver State Armory ammo, it was the 95gr Speer TNT loads. So I know the ammo isn't in question.

What gives guys, any idea's I can use to try and solve said problem.

Is it clean?

Light primer strikes can be caused by too-deep primers in the ammo, a light hammer spring, or an out of spec firing pin. I'd suspect the hammer spring first, as being either too light or incorrectly installed.

What if the bolt wasn't seating into full battery? I know that would effect some guns not sure about the AR-15.
