The tool the qualification is built around. The GEN-12 by Genesis Arms is the first professional-grade, magazine-fed, AR-pattern 12-gauge. It shares the AR manual of arms, so operators proficient on the rifle transition seamlessly — which is what makes a five-day qualification achievable. Maximum effective range 100 m.
◆ Magazine-fed 5, 10 and 15-round capacity — volume of fire, fast reloads under stress.
◆ AR ergonomics — common trigger, safety and charging cut the training burden.
◆ Patented buffer reduces felt recoil for sustained engagement sequences.
◆ Same height-over-bore as a 5.56 AR — no new sight picture to learn.
◆ Modular muzzle — suppressor or standoff device; no choke to maintain.

The baseline effector. 10.5″ or 13.3″ barrel, suppressor-ready, 100 m maximum effective range — the configuration the LASTLINE qualification is scored on.
7″ barrel, 21.75″ overall. The first magazine-fed shotgun adopted under a US federal tender.
5″ barrel, integrated flow-through suppressor, deployable PDW stock, 25″ overall.
World-first semi-automatic 12-gauge bean-bag system, hi-viz, for escalation of force.
Manufactured by Genesis Arms in Idaho, USA, on the DPMS .308 / AR-10 pattern, with a patented short-recoil operating system.
The short-recoil action cycles everything from light training loads to 3″ magnum without gas adjustment — and stays reliable at very short barrel lengths, where gas-operated competitors cannot.
Identical manual of arms, controls and accessory ecosystem as the AR rifles most forces already field. AR-10-pattern parts interchange, simplifying armoury logistics.
The GEN-12 upper drops onto existing DPMS-pattern AR-10 lowers — a force can convert in-inventory 7.62 rifles by issuing uppers and magazines only.
US-made under an ITAR-governed supply chain with ongoing factory support — the natural replacement in a market where legacy magazine-fed shotguns are sanctioned and unsupported.
The effect the standard is scored against. The GEN-12 fires the full spectrum of 12-gauge cUAS ammunition. Purpose-built cUAS loads pattern tightly for airframe defeat at range, while the platform's modularity lets a force match choked or un-choked ammunition to the mission — with no fixed choke to maintain.
◆ Choked 12G cUAS ammunition — patterns as tightly as a choked barrel for maximum density and reach against small aerial targets to 100 m.
◆ Un-choked / cylinder loads — wider close-range spread for fast, close FPV threats and confined engagements.
◆ Choke-free platform — purpose-built cUAS loads pattern from a cylinder bore, so no physical choke is required. A choke kit is supplied for use where cUAS ammunition is not available.
◆ Suppressor-compatible — cUAS loads can be fired through the flow-through suppressor without loss of terminal effect.
High-density tungsten shot delivers the retained energy and penetration needed to defeat carbon-fibre-armoured airframes — where lighter lead or steel, and very small shot, lose effect on the drones used in active conflict zones.
| Medium | Choked 12G cUAS (#4) | Fine shot (#9) |
|---|---|---|
| NIJ ballistic gel | 8.0″ | 3⅝″ |
| Gel + 2 mm carbon fibre | 5.0″ | defeated at 2 mm |
| Gel + 2.5 mm carbon fibre | 4⅛″ | — |
| Penetrates 4 mm carbon fibre | Yes | No |

Both choked cUAS and general-purpose 12-gauge natures can be supplied and, under the localisation roadmap, loaded in region — making consumable resupply part of the sovereign capability rather than an import dependency.
