Did u get the 100$ rebate from browning. And are u going to use the browning choke that came with it. I called them to find the size of it and tech support didnot know or more likely didnt want to look up the info.so far my old armi sanmarco over under with fixed chokes is throwing little better pattern with fed hw 7. I never ordered nitros before. Its been a week and a half. Do they email u when they ship?
