Description
Please note: We strive to provide the most accurate photographs of our product. Due to availability limitations and supply chain constraints, slight variations of the handguard of this upper assembly may occur in the aesthetics of the skeletonizations in between the M-Lok sections.
If you’ve caught that certain spark, and now you’re looking to build your own AR-15 chambered in .300BLK (.300 AAC blackout), you might as well do it with some damned style. Check out this .300BLK built kit. The core of its attitude is a 16-inch stainless steel barrel that’s been coated in black nitride and given bear claw fluting for that extra in-your-face flair. Plus, it’s side-charging, so your new baby won’t be boring. It’s also got a 12″ free-floating M-Lok handguard on which to mount your light, laser, or whatever else.
Plus, we give you most of the extras you’ll need to complete the whole kit. You get a mil-spec buffer tube assembly and butt stock that adjusts in the standard six positions and of course a mil-spec lower parts kit. All you need to do is finish and add your own 80% lower either in 7075 forged aluminum or 6061 T6 billet aluminum. Then of course, top it off with the backup sights or optic of your choice. Please note, mags and ammo are not included.
