What’s Included
- Optic: Predator V2 reflex red dot sight (installed on receiver rail)
The M4 uses an auto-regulating gas-operated action for reliable semi-automatic cycling. Controls include a right-side cylindrical charging handle and a cross-bolt safety. The receiver carries a short Picatinny rail segment that serves as the mounting platform for the included red dot, while iron sights remain available as backups.
The 18.5 in barrel is configured with a cylinder bore (Cyl Bore) and a 3" chamber, offering straightforward compatibility with a wide range of 2-3/4" and 3" 12 gauge loads. The front sight band also clamps to the magazine tube, supporting the protected front post alignment with the rear ghost ring.
Furniture consists of a black polymer, adjustable telescoping stock with a rubber buttpad and a matching black polymer pistol grip. The ribbed polymer forend provides a positive grasp. Length of pull is set at 14.0 in.
Capacity is 6+1 via a fixed tubular magazine. Markings include "PANZER ARMS – Made in TURKEY" with the Panzer crest, reflecting its Turkish manufacture. The matte tan receiver finish gives the shotgun a distinctive, durable look that pairs cleanly with the black furniture.
The installed Predator V2 reflex red dot adds a ready-to-use aiming solution while leaving the ghost-ring sights available as a co-witness or backup, depending on user setup and preference.
