Best bargain rail!


I built my first upper with this rail. The package comes with the rail nut screws spacers and a purple anodized wrench that fits the nut perfectly. The directions are easy to follow even for a novice. Rail line up perfectly first try. And after going M-lok I am never going back for the weight savings are not only in the rail itself but also in the direct attach components that are not as finicky with placement as keymod. I will be buying more of these in the future!
