Listing ID: 1170093 Rockriver Arms BTB LAR15 $775

The BTB is a wonderful gun. You can leave it as is and have everything you need for an excellent tactical carbine or customize the snot out of it. It comes with RRA’s 1-MOA-at-100-yards guarantee and limited lifetime warranty.  The metal finish is traditional AR anodized black. The lower receiver is forged.  The upper receiver is forged A4 (aka “flat-top).  The chamber is cut to take both 5.56 NATO and commercial .223. The barrel is 16” of chrome moly, HBAR profile, 1 turn in 9” (the traditional AR twist), with a A2 flash hider on the end (thread ½-28). The gas block is low-profile. The trigger is RRA’s standard service trigger.  The pistol grip is RRA’s very nice one, overmolded with softer rubber for excellent grababilty.  The butt stock is RRA’s NSP2 6-position one, much nicer for a good cheek weld than the skinny CAR tube. It has an integral rubber buttpad, and integral mounts for quick release sling swivels on both sides.  The handguard is their NSP Drop-in rail with additional mounting points on all four sides (full-length on top and bottom, shorties on the sides).  The sights are RRA’s NSP Flip-up, both front and rear. Use them or fold them down and attach a red-dot or scope.
