I just read JLmoore's post and couldnt call my local gunsmith fast enough. He says its no big deal at all. It never even crossed my mind to have a barrel tapped to accept chokes. I bought a whole new gun cause my remington 1187 is a fixed modified. UN FREAKIN BELIEVEABLE. And my gunsmith only charges $75 to do it. He says the only catch is it has to be a certain thickness. Well guess where my remington is spending the weekend!!!!!!
