870 forend tube assembly questions
I took my new 870 out a week ago or so and put 95 rounds through it - a mix of #8, 00 buck, and slugs. It shot fine, but the pump stroke was a little rough.
Shortly after I changed the furniture, and while swapping the forend, I twisted the arms on my forend tube assembly a bit. No big deal - it only took a few moments to straighten them out.
Since then I've noticed two things:
First (and this may have happened before, too, but I don't recall), if I gently / slowly pump the forend with no barrel attached most of the time it stops at what I guess is the top of the forward motion. Sometimes, however, the forend assembly just slides right out - bolt and all. I'm typically holding the eject lever to cycle the action.
Second, the action is a WHOLE LOT smoother!!! So much so that I actually bent the arms down a little to see if the action would stiffen up, and it does - a lot. I'm not moving them much... I have since adjusted them with what I would call less tension to smoothen the pump stroke.
And the questions:
Did I wack out the forend somehow that the bolt and everything slides out as described above?
Is it acceptable to gently make small adjustments to the forend assembly arms in order to adjust pump stroke resistance?
