New Knight's Armament KAC #21166-2 MRE Rail Assembly SR-15 M4A1 GWOT NIB 

Last produced in 2017 IIRC, this is the Titusville production. Clone correct for M4A1.

This is the 'More Real Estate' Modular Rail Extension which allowed for more Rail space forward of the FSP, one of the more intersting and uncommon pieces of GWOT gear. 

Rare & still sealed in factory wrap, box has storage wear. 

$950 Obo Shipped, Postal Money Order, PP Goods & Services accepted. Will Ship.
