Burnt bronze Daniel defense m4a1 ris ii (block ii rail) that I cut up to make it a FSP rail. Comes with everything it originally came with even the sticker. Shipping is included in the price. Also will throw in a madbull barrel nut shim kit. (Yes I know it’s not a mk18 rail. I put that in the title because some people think they are mk18 rails and call them “long mk18 rails”)
