This review assesses an AR-15 platform rifle priced at $1,700. While the rifle is described as well-designed, fully ambidextrous, and shooting flawlessly with pleasant ergonomics, the reviewer ultimately concludes it's not worth the $1,700 price point in its current state. Specific issues like a sheared bolt release and an unstaked castle nut were noted, though the reviewer acknowledges that stock and grip are user preferences. The rifle is considered accurate but not a "tack driver," and its value is debated against competitors like BCM and Geissele Super Duty.
