Wanted: SureFire Warden direct thread 1/2-28 black

Working on a rifle build and I am looking for a SureFire Warden direct thread 1/2-28 in black.

Don't mind one that has seen some use so long as it isn't too beat up.

Funds are tight so trades are best. I have a variety of parts, red dots, ammo, etc.

Thanks for looking.
