Looking for a new or used billet lower receiver in excellent condition. Don't need ambi controls but it's a plus. Brands I would be most interested in: Noveske Rainier Arms (would also consider RUC Mod 2 complete lower) Mega Northtech Defense San Tan Tactical Umbrella CMT Seekins Lancer Spikes (Gen 2 only) Am I missing something? Send pics and details to four25-four17-four355. Thanks for looking.
