Overview

Built for shooters who want a configurable rifle platform, this model pairs a free-float handguard with a full-length top Picatinny rail and M-LOK attachment slots for adding accessories as needed. The Magpul MOE-K2 grip and DT Carbine collapsible buttstock on a Mil-Spec buffer tube give it a practical, adjustable setup for range work or field use. With a 16.10" barrel, 30-round capacity, and no sights included, it leaves room for the user to tailor optics and setup to the intended role. Its 6.8 lb. weight and 35.87" overall length keep it in a familiar carbine format without adding unnecessary bulk.

Pros

  • Magpul MOE-K2 grip and DT Carbine collapsible buttstock for a familiar control setup
  • Free-float slim-profile handguard supports improved ergonomics and handling
  • Full-length Picatinny rail provides continuous top-mounted accessory space
  • M-LOK slots at 3:00, 6:00, and 9:00 positions add mounting flexibility
  • QD sling sockets on both sides support quick sling attachment
  • 30-round capacity and 16.10-inch barrel configuration suit a range-ready setup

Considerations & Trade-offs

  • No sights are included, so this setup requires the hunter to choose and mount optics or irons separately.
  • The 16.10" barrel and 30-round capacity make it more range- and utility-oriented than a compact, low-profile field carbine.
  • The collapsible stock and 11"–14" length of pull provide adjustment, but the rifle still needs to be set up to match the shooter and intended use.
  • The full Picatinny top rail and M-LOK slots offer flexibility, though they also mean accessory selection and final configuration are left to the user.

  • M-LOK handguard rifle

Suggested Accessories
