870 wingmaster action is stiff

[JB]

Ok I was at a match this weekend and I was finding that my 870 work smooth till it got hot then the action started getting stiff to work. Is there any way of fixing this

Check the clearance between the foregrip and the barrel. I have had 2 of my Hogue forearms lately that have had to be relieved because the would bind at the end of the stroke. I had to take off some material at the receiver end of the forend.

This^; had the same problem when the barrel heats up it expands enough to make it stiff.
