AR15 SPR Straight Top Rail for Gen II Forearms

This rifle length SPR Straight top rail is a full Picatinny rail that connects the receiver to the forearm. This top requires the 8.5" rail with lugs in order to connect top rail to forearm. This creates a rigid platform ideal for mounting accessories.  This top rail works with both the Gen II round forearms as well as the Octagonal forearm with M-LOK.
