This upper has seen 40 rounds of Black Hills V-Max only. It has a Phantom flash hider and a Bushy VMAS flip up front sight for better use w/ a ACOGor magnified optic as the front sight will not be in the picture. A divorce is forcing me to liquidate some items. These sell for $585 from Bushmaster. Sell shipped lower US for $425. For serious inquiries e-mail me at Foldemfast@ao.com and I will send pics.
