AR-15 Platform Mag Attachment Block

For AR platform rifles that either do not have an available picatinny attachment or for which you want a uniform attachment point.  The AR-15 Platform Mag Attachment Block fits all AR-15 mag wells (AR-10 compatible variant coming soon).  Made of anodized aluminum, the Mag Block has a steel mag catch insert and brass knob.  The adjustable leading edge/knob and machined pic rail (patent pending) provide for a zero movement/rock solid attachment for any application.
