Works much better than that stupid cheaply put together armaglock mag release kit. You have to use the mag catch that came with your lower parts kit for this where as the armaglock came with one that was in two pieces.

Sig 556 SWAT compatible

This is the Patriot Mag Release for the Sig .556 SWAT, not the regular .556 version. The cut-out portion of this AR-10 version fits perfectly.
