BCA 6.5 Grendel 20" Upper w/ 15"Mlok  Rail: Comes with an 20" Black Melonite Straight Fluted Barrel 1:8 twist w/  Rifle gas system. These barrels are 100% made in the USA and are very reliable and accurate. The 15" MLOK rail has a slim profile. Built with a US forged upper receiver like Anderson, Aero Precision etc.. depending on what we have in stock. We test fire all of our uppers to assure proper function and reliability. Not to mention we stand behind our builds and if you have any problems we will work with you to solve them. This upper is sold WITH the BCG & CH. Although we do carry several different Bolt Carriers and Charge Handles to complete your upper. To do this you would simply select which BCG & CH you want to be shipped with your upper plus you will save money buying them together. We do offer custom builds as well!! However you would have to call us for product availability and a quote. Need magazines?? Check out our magazine section and add some to your cart before you check out.

Please note most of our uppers are currently in stock and usually ship out within 24hrs of purchase. However, because our stock fluctuates frequently we ask that you be patient and please allow 5-10 business days to build, test fire, and ship your upper. If you're worried about lead time please call us for updated inventory.

WARNING!! If you use reloaded ammunition with upper and lower assemblies all warranties and returns are null in void.
