Armsan Phenoma Carbo Inertia is a semi-automatic smoothbore hunting shotgun combining an inertia-operated action, a synthetic Soft Touch stock and a practical 710 mm barrel. This configuration is chambered in 12/76, with a 5+1 capacity and a listed weight of 3.100 kg.
Inertia System means that the action uses recoil energy to cycle the bolt. Combined with the rotating bolt head, it provides a clean and practical semi-automatic operating system for hunting use.
A semi-automatic mechanism that uses recoil energy for its operating cycle.
During firing, the inertia mechanism uses recoil movement to unlock and cycle the bolt. The spent cartridge case is then extracted and ejected, preparing the system for the next cycle.
The bolt uses a rotating bolt head, meaning the locking head rotates during locking and unlocking of the action.
This Carbo Inertia version also features a cartridge cut-off and a separate unloading button. The cut-off temporarily interrupts feeding from the tubular magazine when required.
The Carbo configuration uses a synthetic stock with Soft Touch coating. Soft Touch is a surface treatment with a softer, more tactile feel than standard smooth synthetic material, improving contact with the stock.
A soft-feel surface coating on the synthetic stock for a more comfortable and secure hold.
The smooth-profile recoil pad is designed to support fast and unobstructed shouldering without catching unnecessarily on clothing.
Attachment points are provided for use with a suitable carrying sling.
The Phenoma Inertia Synthetic platform uses an enlarged loading area for easier access to the tubular magazine. On this Carbo version it is complemented by a cartridge cut-off and a separate unloading control.
Additional space around the magazine loading area for more convenient handling.
The technical term for the cartridge cut-off – a mechanism that interrupts feeding from the magazine.
A separate control designed to make unloading the shotgun more convenient.
The sighting system combines a stepped rib, a mid-bead intermediate reference point and a bright fibre-optic front sight.
A raised stepped sighting rib that provides a clearly defined sighting plane along the barrel.
An intermediate bead that complements the front sight and helps reference the sighting plane.
A bright front reference point designed for easy visibility in changing light conditions.
The Phenoma Inertia receiver is made from light alloy with a matte black finish and is factory drilled & tapped – drilled and threaded for installation of a suitable compatible Picatinny rail.
Factory-drilled and threaded mounting points for a compatible rail.
The receiver uses a lightweight metallic alloy with a practical matte finish.
A suitable compatible rail can be added when a compatible sighting device is required.
This configuration uses a 710 mm / 71 cm / 28" barrel. The official Phenoma Inertia technical specification lists 50 mm Standard Multi Chokes – an interchangeable choke-tube system.
A classic and versatile barrel length for a semi-automatic hunting shotgun.
12-gauge configuration with a 76 mm / 3" chamber.
An interchangeable choke system allowing the use of a suitable compatible choke tube.
