Greetings, If your FF SWS handguard is to replace the mid length handguards on the 16" AR10 A4 carbine size, and in excellent shape, I'd like to purchase from you. Please email pics of your's (if possible) and details to me at email@example.com if you would. Payment will be US Postal Money Order sent via Certified Mail, with numbers emailed when payment sent, if OK with you. I will email and IM you this same message to make sure you get it. Thanks Much In Advance, look forward to hearing from you...............C.W.
