If you're searching for a super flexible M4/AR-15 AEG with an ultra-modern aesthetic and internals to rival the best, the Delta Armory R15 FREYA™ Gen.2 13" M4/AR-15 AEG should suit you perfectly. Boasting a full metal build on the outside and pre-upgraded internals inside, the FREYA's party trick is the Delta Armory EAGLE ETU™, offering more programmable functions than previous versions and allowing you to run the FREYA™ as a DMR with semi-auto only and a stronger spring and quickly swap the spring and fire control options for a CQB skirmish the next day. 

Internally, the Gen.2 FREYA™ is better than ever, boasting the perfect combination of the EAGLE™ programmable MOSFET with the best bits of Delta's ETU series internals. These include CNC steel 16:1 high-speed gears, a CNC steel cylinder and spring guide, a CNC aluminium piston head and cylinder head and a high torque motor to top it off. These parts join the usual Delta Armory SHS reinforced tappet plate, SHS piston and 6.03mm tightbore inner barrel, resulting in an impressive down-range effect and a significant improvement over the original but still respectable FREYA™ Gen.1.  

If you're looking for a lesser-seen design with AR compatibility and the best combination of Delta Armory pre-upgraded internals, the R15 FREYA™ Gen.2 13" M4/AR-15 AEG from Delta Armory is a fantastic option and better than ever before!
