The upper is an early, complete factory Noveske Gen 3 that was on a factory SBR that I bought at Yeti Firearms years ago - 2017 IIRC.  They had already sold the lower.  Chrome lined, 1/7 twist, manganese phosphate-coated barrel chambered in 556 nato with the famous Flaming Pig flash suppressor.  Mil-spec BCG that came with the upper.  Noveske charging handle and key-mod handguard.

The lower has a factory Noveske, N4 Gen 2 *forged" receiver (non-chainsaw), a Maxim CQB arm brace with JP Silent Capture Spring system and a Geissele SSA-E trigger.  These Gen 2 forged lower receivers are getting very hard to find and are not cheap, especially one in this condition.  No expense was spared on this lower.

Very low round count and very nice condition, as you can see in the pics.  

$2800 obo

I will only meet at the Phoenix PD Black Mountain Precinct on North Scottsdale Road or at the Maricopa County Sheriff's substation in Cave Creek.

If you're curious why I'm advertising this with the arm brace, a Federal Judge just ruled that NRA members can continue to use them on pistols - and I'm in the NRA.

Thanks!
