Steel low Micro Gas Roll Pin .750 Hide Under Quad Rail

Hard coat type 3 mil spec anodized finish, solid precision machined construction.

750 is used when installing a rifle length quadrail to allow the quadrail to slide through the barrel.

The gas tube mounts to the micro  just like it would to your regular A2 post ,

but it is sleek and small to allow a longer rail to be placed.
