The MAR-12 was designed specifically to be able to withstand dusty and sandy environments, warm and cold climates, as well as be lightweight and easy to use in confined spaces such as buildings. The initial MAR-12 has an almost carbine length, while its folding adjustable stock allows it to be stored easily for transport, in vehicles and aircraft for example. This makes it suited to be used as an infantry and crewman's weapon.

Its modular design also includes a support weapon and marksman rifle variant, allowing for interchangeable parts to be used across an entire squad, reducing strain on logistics and resulting in fewer different parts being required for maintenance.
TPS redesigned the action to integrate the steel with polymer, which is much lighter than the fully steel receiver of the original AM rifles. While the upper receiver is machined steel and the receiver top features a Picatinny rail, polymer has been introduced to the lower receiver of the weapon to reduce the gun's weight. This has led to a very lightweight, compact and reliable rifle with modern furniture and ergonomics. A departure from the AM rifles' "rock-in" style of magazine catch, the MAR-12 uses a last round bolt catch and a single-press drop out magazine release, in which the bolt will hold open after the last round has been fired, until such a time as the bolt catch is released. This significantly reduces reloading times during combat. The Jaghond uses flip up iron sights and a collapsible stock on a folding mock-buffer tube.
The gas tube, unlike the AM-64 system, is mounted on the rifle via a dovetailed slide machined on the receiver upper-front block. This avoids any movement of the gas block influencing barrel vibration, which would degrade accuracy.
The original AM-64's weight was 4.6 kg, but thanks to modern manufacturing techniques, the MAR-12 weighs a total of 2.96 kg, almost half that. The trigger is a two-stage trigger for all variants, resulting in more control over shots and a more crisp and smooth 4 lb. 13 oz. [4.8 lbf, 21.4 N] trigger pull.
The side forearm rails of the weapon have central grooves to provide routing channels for electric wiring used by pressure switch activated accessories. The forearm comes with quick detachable polymer covering panels that can be mounted to protect the rails when a side or bottom rail has no accessories mounted to it.
The barrel is chrome-lined, cold hammer-forged (similar to the AMW-280), with a 1:7″ twist for 5.56×45mm NATO, 1:9.5″ for 7.62×39mm and 1:12″ for 7.62×51mm NATO. In order to improve reliability of the AM's action, the system has been fully enclosed within the upper receiver, with a dust cover over the ejection port to prevent dirt and debris from fouling the action. The enclosing of the action results in far less open spaces in the gun for dirt and sand to ingress into, something which the AM series suffered from due to its lineage of being an AK design.
