Troy BattleRail Drop-in CAR/M4-7" Black

This is a Troy Industries BattleRail Drop In CAR/M4-7" Black that i bough, installed and quickly removed from my AR-15. It's been sitting in my closet for a while in the original package. The condition is pristine and there is nothing that indicates that was installed and removed. Judge by the pictures. More pictures are available upon request. Thank you! For additional $20.00 I will include the Troy Rail Covers Full Length (3 Pack)-Black.
