Forward Controls Design AR-15 and M16 Carbine Receiver Extension Black

Forward Controls Design AR-15 and M16 Carbine Receiver Extension Black. Made from impact extruded 7075 aluminum with rolled threads and dry film lubed interior REF differs from most carbine receiver extensions thusly: Additional drain holes in the 2nd and 5th latch positions in addition to the TDP spec carbine RE drain hole at the end of the RE; Laser engraved stock latch position indicators on both sides. REF’s stock latch position indicators are located at 3 and 9 o’clock because many of the popular and superbly designed Magpul stocks don’t use the lock release lever found on the Colt M4 stocks and SOPMOD stocks they therefore lack the release lever pin hole on top of the stock body numbers engraved on top are visible to the users but they no longer correspond to the actual positions. By relocating the numbers on both sides users can easily and quickly identify the latch positions of their stocks.
