This is a Buffer plug designed to work with Hoffman lowers. It will work with other lowers but, it may not blend in as well. It is beefed up version of Maverick0197's plug by Scott_Tx. The M4 bolt has more material between it and the buffer plug to make it stronger. There is also a small recess for a washer.
Hardware required:
2x Flat head M3 x 13mm
1x Socket head M4 x 15mm
Installation:
Using a 6mm allen wrench, screw the threaded Plug into the lower until the back of the plug is flush with the back of the lower.
Insert the M3 nuts into the back of the Endplate.
Using the M4, attach the Endplate to the plug.
Using the M3's, attach the Rail to the Endplate.
