NBS 16 .308 Heavy Midlength M-LOK 1:10 AR-10 Slick-Side Complete Upper

***Please note that this receiver is DPMS Gen I/LR308 pattern. We are very happy to announce our very first NBS AR-10 complete upper! With our customers in mind, we wanted to create a complete AR-10 upper that is lightweight, accurate, and reliable. We started with a 16" nitride-finished 4150V chrome moly vanadium barrel chambered in 308 WIN with a 1/10 twist and mid-length gas system and paired it with our NBS High-Profile AR-10 handguard. Our AR-10 handguard features a patent-pending ASAL locking system to virtually eliminate any handguard movement/lift. The slick-side upper receiver is precision-machined from forged 7075-T6 aluminum, then Black anodize hard coated to MIL-8625 Type 3 class 2. Our NBS AR-10 BCG is designed with a 9310 steel bolt and nitride treated for durability. The carrier is made from 8620 steel, with a nitride-treated gas key properly staked with grade 8 fasteners. A charging handle is also included. Buy with confidence, this upper is backed by our 30 day satisfaction guarantee. Buy it, run it, abuse it, and if you aren't satisfied you can send it back for a full refund. Lifetime Warranty Guaranteed Sub-MOA performance with match grade ammo and proper shooting technique Made in the USA Disclaimer: Does not fit Aero's M5 lower receiver.
