Anybody know of a source in the Portland area to get coiled roll pins (specifically for an AR trigger guard)? The hardware stores I've looked at only have slotted ones, I hate slotted ones, I don't know why anybody would choose slotted over coiled. Everywhere I've found online wants $10+ for shipping! It's a freaking pin, just drop it in an envelope, stick a $0.49 stamp on it, and put it in the mailbox! I digress. Anybody know of a source?
