Custom Potomac Armory SBR Mod 0
What else can we say? At Charlie's we love military clones, but if you cannot have a military Mk18, or you are just looking for something different, this is one of the best of the best. Colt and Geissele parts in a mosh pit of excitement !!!
- Colt mil-spec M4 upper receiver
- Colt FBI 11.5" HRT barrel -- heavy profile
- Geissele 9-1/2" Mk18 DDC a more modern FDE, if you will
- Geissele black oxide blackened gas block, pinned
- Fully assembled, with nitrided black (made in USA) gas tube
Bear with us. This is a concept upper. Once built, we will provide pics. No issues, as we have pre-sold a handful.
