Doesn’t get much better or reliable than this with long stroke piston system. These sell for $1300+ new. Less than 100 rounds through it. Cloud defensive light control system and Holosun not included. $900
Possible trade for higher end 14.5 or 16” upper, I can add cash on my end. Really trying to get funds for Knights Armament SR-15 upper.
Here’s the specs:
Factory model 18-2M107UA0B
Caliber 223 Wylde (223 or 556)
3lb 10oz weight
17.25 inches overall length
7.75 inch 41V50 FNC LIFE HD barrel
1:8 twist threaded 1/2X28
PWS CQB compensator
7 inch MLOK handguard
Integrated front Picatinny rail sections
Lightweight forged upper receiver
Eliminated forward assist
Pistol-length long-stroke piston system
3-position adjustable gas block
Radian Raptor LT charging handle
Limited lifetime warranty
