    Just wondering what would cause light primer strikes on a MX8. It's happening in Both Barrels.

    Check your firing pins, pull trigger assy and press the pins forward to full travel. Could be broken firing pin return springs coiling up. Could be 2 piece pins shortening, could be crud build up. Could be cracked hammer springs..

    I have had this problem myself. Replaced leaf springs new firing pins and springs.Also check if you have concentric ring indentations on the breech face.I still gt the odd failure to fire with the finocchi and cheddite brands. I assume your primers aren't set too deep.

    The firing mechanism on an MX8 receiver works a little like dominos falling. One of the things that can cause light strikes is a gummed up or dry cocking rod. If it doesn't move freely and smoothly when you push it rearward then it can prevent the hammers from making their complete travel to the firing pins.

    If all the other, more apparent things, are fixed and you still have the problem then you should remove the cocking rod, clean both the rod and the dovetail it travels in and the pin and detent spring thoroughly with a Gun Scrubber type cleaner and maybe a tooth brush. Lubricate with a light oil and usually that takes care of the light hits.

    Check the cocking bar, sometimes they will cause the hammers to bind if they get bent due to damage from removing and replacing the trigger assembly
