      Colt M4 lower receiver

      Always great dealing with AU! Just wish y’all would get away from USPS! Ordered mine the day before a friend ordered his, he received his in about three days, mine took over a week! Will definitely use AU for future purchases, I’ll just choose another shipping method.

      Great value for builders, was expecting a colt box when I received the package but did not come with one. Package was wrapped and protected extremely well nonetheless. Great buy!!

      Colt Carbine Lower

      Everything came as expected, and the lower was in overall good condition. Small scratch on the area near the buffer tube, but it’s purely cosmetic. Arrived quickly and functions as it should. Already have a second one on order for different clone build.

      Legendary Colt product. One of the only places in stock. Very reasonable priced. Arms Unlimited is my go to retailer for hard to find firearms and accessories.
