Not 13” actually 13.5” - Geissele 13.5in MK14 Super Modular Rail

Great product but not 13”. It’s the newer 13.5”. I recommend these rails but really wanted a 13” for my 13.7” build. These rails are proven and have worked great on two of my other builds. I continue to use them. Just wanted a short version to build my 13.7”
