I have an LWRC M6A3 upper receiver in practically new condition for sale. I'm the first owner and only put less than 50rd through it, most for comparison purposes. This upper comes with the following features: Cold hammer forged barrel Latest one-piece nickel coated BCG 4 adjustable gas settings, built in front BUIS Free floating rail system Built in front and rear BUIS See link: LWRC International LLC - M6A3 5.56 Uppers Reason I'm selling is I decided to go with a different upper. It retails for $1900, and I'm selling for $1550 OBO. I'll also consider trades for Aimpoint H-1, Insight MRDS, or similar mini red-dot sights plus cash. I have an outstanding buying and selling record on other gunsites and eBay, references available upon request. Feel free to email me with questions: email@example.com. Here's some pics. More pics available upon request.
