Testing the waters on my upper receiver group from my Colt SOCOM M4A1. Everything is factory with exception of the flash hider, which has been replaced with a pinned and welded BCM A2X, since it accommodates a bayonet if added, and maintains NFA barrel length legality. Less than 100 rounds have been fired through it.
NOTE: The FSB was marred at some point to get the taper pins out, so it has been smoothed out on the bottom left side and re-phosphated. It is unnoticeable to the untrained eye, but want to be transparent about it.
- 14.5 Colt SOCOM barrel with F-marked FSB, cage coded
- Knights Armament RAS quad-rail with cage-coded rail covers
- Knights Armament VFG Broomhandle
- BCM extended A2 flash hider, pinned and welded
- USGI charging handle
- Colt C-marked Bolt Carrier, MPC Bolt
- Colt Cerro Forged (Keyhole) Upper Receiver, mil-spec anodized finish with dry film lube inside
- Matech BUIS
If interested, would prefer to meetup in Fort Myers area. Thanks for looking!
