While my 425's in the shop having a new bead put on, I took my trusty 870 out the the trap range last night. One of the things I love about the 425 is the long LOP and I'd like to get my 870 to the same spot. Does anyone have any good suggestions on adding 3/4" or 1" to an 870? It's got wood furniture and the supercell recoil pad.
