 BUILD SPECS: Elite Rifle on Integrated Rail Platform*:

*The Integrated Rail Platform is an ATAC Defense patent pending system in which the upper and handguard are assembled then machined with a full-length inverted keyway down the top. A one piece picatinny rail is machined with a receiving keyway, and bolted down the top of the upper and handguard. This locks the handguard and upper together with a one-piece sight rail with no interruptions or breaks. This process eliminates the need for anti-rotation tabs, and eliminates the fear of twisting a handguard or breaking a barrel nut loose. It also provides a stable picatinny platform so night vision or a thermal optic can be mounted in front of your day optic without fear of the rail twisting or moving. Other uses: Iron sights, align the front and rear sights or if you’re looking for extra eye-relief split optic rings could be utilized.

    Absolutely Awesome. The 1/7 twist barrel loves 62+ grain projectiles, and I like the stopping power of heavier bullets. The fit and finish is exceptional. Keep up the excellent work!
