Overview

Built around a full polymer upper and lower receiver set, this rifle is aimed at hunters and shooters who want a lighter, more affordable platform with an ergonomic feel. Its M-LOK handguard uses slots only at the front, while the rear sections are reinforced with solid polymer to support heat management and help limit zero shift of rail-mounted sights and lasers. Chambered in 5.56x45mm NATO and finished in black, it comes ready with a 30-round magazine, blade-style pistol grip, and flip-up iron sights.

Pros

  • Full polymer upper and lower receiver set for a lighter rifle package.
  • Polymer construction balances strength, versatility, and affordability.
  • M-LOK handguard provides practical accessory mounting up front.
  • Reinforced rear handguard sections help reduce heat transfer and rail shift.
  • Includes one 30-round magazine, blade-style pistol grip, and flip-up iron sights.
  • Chambered in 5.56x45mm NATO with an all-black finish.

Considerations & Trade-offs

  • The full polymer receiver set is designed to keep weight and cost down, but that material choice may not suit buyers who prefer a traditional metal receiver feel.
  • The M-LOK handguard only provides slots in the frontmost section, so accessory placement is more limited than on a fully slotted rail.
  • Rearward sections of the handguard are solid polymer, which supports heat resistance and reduces zero shift concerns, but it also means less mounting space in that area.
  • The rifle is chambered in 5.56x45mm NATO and includes a 30-round magazine, so it is set up around that specific platform rather than being a more flexible multi-caliber option.
