I'd just like to make a little update: Milarm and P&D no longer carry Choate stocks... Both of them just got back to me over the past couple days. I know Lever Arms in Vancouver doesn't stock Choate, and I'm not sure about Italian Sporting Goods. Reliable Gun does sell Choate, but you're looking at a markup once they get the parts in. I just emailed Brownells about ordering a couple bits in (they didn't have them listed on their site), so we'll see what they say once they get back to me... hopefully it'll be by the end of the week.
