Forward Controls Design ACOGs Parallel Red Dot Sight Mount, Black, PMA

Forward Controls Design ACOGs Parallel Red Dot Sight Mount, Black, PMA. It is not an ACOG mount. PMA is a spin off that grew out of the side folding backup sights project (think Bren Gun offset sights). Side folding offsets sights would be costly to produce a modern RDS would be faster and easier to use and the parallel mount was created to do just that. The red dot mounting 5 slot Picatinny interface runs parallel to the rails on the handguard and upper and is elevated to provide clearance for red dot mounts and bring the red dot to eye level of the shooter. PMA can be mounted on the upper receiver or a railed hand guard with available Picatinny rails at 12 o'clock it can be mounted with the cantilevered Picatinny rails on the left or right of the weapon. PMA's MRDS mounting Picatinny rails have 5 slots sufficient for almost all MRDS Picatinny mounts. A MRDS thus mounted is fast to use that takes but a slight shift (less than an inch) of the user's head to acquire the dot. Optionally the user can choose to rotate a carbine or rifle with MRDS mounted on PMA but no longer is necessary to rotate the weapon 45 degrees PMA only needs 10 degrees of rotation. Do note that PMA isn't a 45 degrees offset mount the way it's mounted and used is different. A red dot sight mounted on the PMA should be INBOARD not OUTBOARD like a 45 degrees offset mount. When mounted on the outboard side of the handguard PMA behaves like an angled offset mount but does not require as much canting as a 45 degrees mount.
