I would put it in the wtb firearm section what you want and mention the trade. Also post what you have in the accessory section with a price and trade offers. Not against the rules in my eyes.
Pics and COMPLETE INFO,or some will just pass it by as someone that is really unsure of what they are selling.
It is not my "job" to go to Google to try and find out what is ACTUALLY for sale. --- SAWMAN
