The rifle’s flat-top receiver provides a versatile platform for optics, magnifiers, and tactical accessories. Whether you’re building a close-quarters configuration or a field-ready setup, the platform adapts seamlessly to your loadout.

Licensed Daniel Defense RIS II Rail System

A standout feature of this SOPMOD Block 2 configuration is the CNC-machined Daniel Defense RIS II aluminum handguard. This fully licensed rail system includes laser-etched trademarks and provides a rugged, lightweight mounting platform for lights, grips, lasers, and other 20mm accessories.

The heat-treated CNC construction improves durability, ensuring smooth cycling and long-term reliability even under demanding use.

Realistic fire controls and an improved bolt locking lever enhance immersion and function. The redesigned lightweight magazine further improves handling by reducing weight by approximately 35% compared to previous generation models—making extended gameplay more comfortable without sacrificing performance.

Adaptable Ergonomics for Any Playstyle

The adjustable CRANE-style stock allows users to fine-tune length of pull for optimal comfort and control. Combined with the ergonomic polymer pistol grip, the rifle provides excellent handling in both close-quarters and open-field environments.
