Surplus M4A1 Block 2 Complete Uppers

Will trade for Leupold MK6 M5C2 3-18×44 w/ illuminated Tremor 2 reticle, or partial trade for a FDE Surefire RC2.

M4A1 Block 2 uppers built with 100% good condition surplus parts. Complete minus rear sight. Started as gov surplus 14.5″ Colt M4A1 uppers (gov profile) and were built with Army surplus DD RIS II Rails, Surefire 4 Prong flash hider, CQD Sling mounts, USMC Surplus dark FDE KAC 99051 front sights. DD MK12 gas blocks. Colt C marked carriers and factory charging handle. These are basically not clones, as they are 100% milsurp components. Barrels gauged and headspaced, carriers have new gas rings/key and staking, everything was sonic cleaned and tested with 25 rounds. Both funcfion flawlessly. $1650 per, price is firm and includes shipping but not PP fees. Thanks!
