AERO PRECISION - M4E1 350 LEGEND ASSEMBLED UPPER RECEIVER W/ATLAS R-ONE

350 Legend offers great performance for hunting medium game with the AR15 platform. Being a straight walled cartridge, 350 legend allows for legal hunting in some states or jurisdictions with regulations that prohibit the use of bottleneck cartridges that are commonly used for hunting in the AR15/AR10 platforms.

NOTE: Ensure you comply with all rules and regulations for your specific hunting area.

This assembled upper includes Aero's ATLAS R-ONE Handguard. The R-ONE handguards are designed with size and weight in mind, while still providing plenty of real-estate to accommodate any attachment needs the end user may have. Aero's proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
