CMT HDM-A2 17" Arca Rail

This rail system is meant not only to give you tons of picatinny rail surfaces, but also to make it possible to mount ARCA/Swiss tripod and bipod systems to your AR-style rifle. The overall shape of the rail has also been enhanced to make it easier to shoot from a rest or bag, meaning that this is a great choice for those looking to get maximum potential accuracy out of their rifles.
