Multi-Caliber system with operator level quick caliber change. Calibers range from .223Rem to .50BMG and similar calibers. Planned also for Rimfire calibers (.22Long-Rifle etc.). Allows for multi-role application and optimal training and operating cost by allowing to train with lighter / cheaper caliber and compete with heavier calibers when needed. Since all calibers are used in the same rifle operators have the same ergonomics, controls and trigger characteristics and units have only one system for all calibers and applications concerning maintenance and re-supply.
Adaptive Chassis System allows to adjust the rifle system to the caliber/magazine on the workshop level. Thereby setup for smaller caliber shortens overall length and bolt travel to a minimum. Also allows for use of out of specification (CIP/SAAMI) extra long bullets from magazine, which otherwise would be single-feed by hand, which extends engagement ranges with optimal bullet selection. For operator level quick caliber change the chassis system would be setup for the largest caliber /magazine used.
Bullpup rifle configuration allows for shortest possible overall operating length. Superior stability compared to folding stock rifles due to no hinge connection. Folding stock systems have to be manipulated between their shorter transport and longer shooting configurations. The Bullpup system is always ready and short, even compared to a not ready-to-fire folded stock rifle – in some configurations even with suppressors mounted at equal barrel length.
Individual overall length is determined by the 8cm long bolt system + magazine length + barrel length + muzzle accessories (muzzle brake, suppressor, etc).
Although the Bullpup system is already short, the added Take-Down system allows the operator to quickly break down the rifle into two smaller parts for transportation and packaging. This makes the overall length of the two parts minimum 53cm or the actual barrel length, which ever is longer. Due to how the receiver separates from the chassis the „Precision“ parts (barrel to scope) stay together and keep Zero, while the „Ergonomic“ parts stay adjusted to the shooter.
Additional benefit of the Take-Down system is the quicker and more reliable change of calibers and configurations. Like other Multi-Caliber systems the receiver mounts the barrel similar to a chuck. And although the receiver has one of the longest barrel chucks in the market, changing barrels in any Multi-Caliber receiver is not a guaranteed technique to return to Zero, especially on the first shot. Therefore changing Multi-Caliber systems needs to be re-confirmed to Zero by actual shooting. If the caliber or just the barrel length changes, all attached aiming devices (rifle scope, red dot, BUIS, LASER) have to be readjusted to return to Zero for the new barrel. In most cases this cannot be done in the field. With the Take-Down system the barrel stays with the receiver, the individual sized handguard and all attached and zeroed aiming devices. This also works between different rifles and shooters since the zeroed receiver of one rifle can be mounted to another rifle chassis ready to go, which is not possible with traditional Multi-Caliber systems alone. On an operational unit scale the individual chassis stay with the shooter and keeps their personal ergonomics and trigger setup, while the caliber/scope/accessories stays zeroed with the receiver and can be interchanged between chassis quickly and reliable.
Ergonomics
Fully ambidextrous chassis system, including ejection side selection (left or right). Shooter can select ejection side at any time before cartridge extraction. Thereby the shooter can select ejection due to shooting left- or right-handed or operational considerations (cannot eject in one direction due to space concerns; right-handed shooter has to shoot left-handed). Bolt-handle optional left and/or right, longitudinal adjustable to the ergonomically correct hand positions of the shooter – compared to traditional Bullpup rifles with bolt-handle uncomfortable far to the back). Allows for bolt manipulation from both sides and shooting left-handed and right-handed ergonomically correct without first needing to convert the rifle for it. Safety selector and magazine release integrated in the grip/trigger group. Additional magazine release close to the magazine. Fully adjustable trigger with integrated direct and second-stage configuration. Integrated monopod in the back.
Length of Pull (LOP) adjustment by adjustable pistol grip position, with no change in overall rifle length, as is required with tradtional adjustable stock systems. Full size fixed butt pad works for all shooting position without need for height adjustments. Due to Bullpup design no check rest adjustment needed – compared with traditional rifle stocks – rifle scope height adjustment by use of correct scope mount selection. Thereby no moving ergonomic parts for superior stability while aiming and shooting and no risk of unintended adjustment. One piece full length scope and accessory mounting rail – no misaligned two part main rail. Patented mounting of the handguard to the receiver keeping Zero reliably. Loading check without re-opening bolt via haptic firing pin indicator.
Compared to traditional “free-fall” magazines, the active magazine ejection system pushes the magazine out of the rifle even when not facing down with gravity. Due to not being “free-fall” the inserted magazine is not loose in the magazine well, making no noise and having misaligned cartridge feeding problems. Magazines are double-stack / single-feed allowing for high magazine capacity with short length.
Safety
Patented bolt lug design is self-inhibitting under pressure resulting in stronger locking during the shot. Due to the lug design the bolt and barrel extension bend towards and not away from each other under extreme pressure, making them a more compact unit and not separating catastrophically. This also allows for an open barrel extension design giving additional pressure relief area in case of cartridge failure. Furthermore allows for easy visual inspection of the barrel extension, cartridge head space and cleaning. Reliable primary extraction of the cartridge due to threaded lug design pulling the cartridge while opening the bolt. Fully controlled feed and ejection of cartridge with fixed ejector. No risk of blockage due to misalignment of loose cartridge. No risk of double feeding. Ejection distance from rifle controllable by the speed of bolt handle
pull back.
Patented lock is an improvement on the known hand cocking systems, in that it uses the spring force to actively pull back the hammer away from the firing pin when in the “Safe” setting. This in comparison to normal hand cocking system, where the spring force is only reduced to “hopefully” not ignite the primer while the lock system is always wanting to move towards the firing pin. Due to the bolt system design the lock can only be cocked when the bolt is closed, thereby making sure ignition only happens when the chamber is operationally safe to fire. Three position safety with locked bolt.
