I have a Colt preban M4orgery built on a 6530 preban lightweight sporter lower. Lower has 50 rds fired thru it. Upper is new factory Colt LE6920 16", 1/7. Both upper and lower finished in Lauer Colt grey. GG&G sling adapter. Factory Colt buffer tube and "H" buffer. VLTOR stock. Hogue grip. New Knights RAS with forward handle. ARMS#40 BUIS. I will trade/sell any combo of equipment with the rifle. Looking for a Mitchell Arms preban Yugo AK in 7.62 or a factory preban H&K 93 for trade plus cash. I would also entertain reasonable offers to sell the rifle outright. Please email for pics/questions.
