What may also be an issue is a bit of play in the feedtube. I'm not sure how much it is supposed to have, but i can wiggle the feed just a hair when the marker is fully assembled. Since this serves as the pump guide it does of course affect the angle of the cocking rod as a result. So it would be possible to either catch the hammer bolt head or not depending upon if you were twisting the pump back a hair when you cocked the marker or not. (thus tilting the feedtube closer to the barrel than parallel, and making the cocking rod angle downwards a hair as a result)

Sorry if that paragraph makes no sense.
Well that rules out a short on in the hammer. I do use some 1/2" shoulders int he DRV.

There should only be 1/32" difference in spacing between the botl heads and the cocking arm. The front bolt should go through the pump arm, through the breech, through the feedtube and bottom out on the front plug. There is likely a little bit of movement since it has to be assembled/dissasembled in the field by end users. Some end users like to hammers instead of taking their time.... or worse yet an arbor press

They should be .625" long. I'll verify the one I have at the shop tommorow. They should be a min of .615"

Don't recall ever having run into this one before. i'll look at the one in the shop to see what I can see.
