Do not try to sell your gear in this forum. Read here for how to do it properly.
Plainly put - don't. We have a great Buy/Sell/Trade section, and that's where business and transactions need to take place. We have been seeing an awful lot of "hey, I've got Gun X for $250, PM me". The same rules that apply to PBTalk apply in here. If you really feel like you have something a thread starter would want to buy, send them a private message. Posting your gear for sale in someone's thread is going to draw a warning or an infraction.
