Bought this last year for my Sig 716 to replace the awful factory carbine length quad rail, this was honestly the perfect solution, giving me more room for attachments, more length to hold the rifle stable, and significantly less weight than the factory rail.
this is the 13.1" rail, the cheapest I could find it online was $275, I'll take $200 for it
