Moderator Eagle Vision Sigma M4 Interchangeable 1/2 UNF

With the Eagle Vision Sigma M4 Interchangeable 1/2 UNF, you can easily switch between calibres by swapping out the internal liner for a liner of a different calibre, without having to open up the moderator (tools included). The end cap can be interchanged as well, to be able to use a different thread (extra end cap not included).
