I'm waiting to hear back from Mossberg. What mount did you use for your fastfire, To get one from Mossberg is pretty expensive for a twenty. I'm waiting for a quote on a stock from them and we have been using godagrip cheek risers on our rifles and shotguns and they work pretty well. Grabagun seems to have the best price for the gun. Is your replacement stock camo and how much did it bring the weight up? I've got till next season to get the gun but my Wife says she knows its going to be a lot sooner. Thanks for your input.
