Black Rain Ordnance Spec 15 Features The Black Rain Ordnance Spec 15 is built around forged aluminum receivers and a 16 inch 4150V chromoly barrel giving the rifle the strength and heat resistance needed for sustained range use. Its direct impingement gas system cycles through a .750 low profile non-adjustable gas block a configuration chosen for reliable function across a range of 5.56mm loads. A salt bath nitride coated bolt carrier group resists corrosion and reduces friction during cycling helping the rifle run cleaner for longer between maintenance intervals. The 15 inch M-LOK slim handguard keeps the rifle s front end lightweight while still giving shooters room to mount lights grips and other accessories. A mil-spec G.I. trigger and forged charge handle keep the controls familiar to anyone who has run a standard AR-15 while the included A2 flash hider reduces visible signature when firing. The Picatinny rail on the upper receiver makes the rifle optics ready and this package arrives with a Zero Tech Trace red dot already mounted so shooters can start shooting immediately out of the box. A synthetic XTS stock keeps the rifle light and adjustable for different shooters and shooting positions. The Spec 15 ships complete with a 30 round Black Rain Ordnance magazine a soft case and a range bag rounding out a ready-to-run package for sale at GrabAGun.
