Key Features
- 16.10″ Empire Profile Barrel – The medium taper design reduces weight while maintaining rigidity for consistent accuracy. Why it matters: less fatigue during long range sessions means more time teaching your kids proper form.

- Ambidextrous Controls – Includes an ambidextrous safety selector and bolt catch. Why it matters: left-handed family members can shoot comfortably without awkward reaches.
- M-LOK Handguard – Full-length M-LOK slots for adding lights, bipods, or grips. Why it matters: lets you customize the rifle as your skills grow.
- 10-Round Magazines – Ships with two 10-round mags (10+1 capacity). Why it matters: perfect for range rules, hunting limits, and state laws that restrict higher capacities.
Who It’s For
This rifle is for families who want a reliable .308 AR for target shooting, deer hunting, or plinking. It’s also ideal for new shooters transitioning from .223 to a full-power cartridge, thanks to the manageable recoil from the 16.10″ barrel and adjustable gas system. If you live in a state with magazine capacity limits, the included 10-rounders are a major plus.

- Pros: Ambidextrous controls, lightweight M-LOK handguard, 10-round compliance, accurate Empire barrel, CMMG warranty.
