Single claw mounts can struggle with windage retention. The Hansel extends rearward and includes 2 nylon-tipped screws which "pinch" the receiver in order to eliminate lateral rotation.
Patent Pending
MP5 Sighting Refined
The "Hansel" MP5 optics mount system is designed for ergonomics, reliability and precision. It provides clear access to the charging handle while delivering the stability of a dual-claw system.
Why
Since the 1960s, MP5 optic mounting solutions have typically forced a tradeoff between ergonomics, quick attachment, and durable zero retention under impact. We decided it did not have to stay a zero-sum game.
The Hansel was designed to remove that compromise. The objective was a more rugged, more ergonomic, and more streamlined MP5 optics mount shaped by design requirements rather than imitation.
The Result
1 unitary body and 3 screws that never have to be completely removed. Claw surfaces are integrated, and the mount can be installed with 1 hand in less than 30 seconds.
Does not extend further than the ejection port. This is a key design constraint especially for users with the shorter MP5K receiver.
The Legacy Windage Tradeoff
Mounts must keep the sight fixed in all 6 degrees of freedom, or zero will not be retained during use. Many ergonomic single-claw mounts fail to keep the sight aligned in windage due to the lack of lateral control that the front claw provided in the more traditional configuration.
Tested
Reproducible zero shift approximately equal to the width of the front sight hood in legacy
single-claw mounts. This is not a removal-and-reinstall issue. It is zero shift that
occurs without the mount ever being removed.
Improved
Lateral control features allow the Hansel mount to retain windage zero beyond 10 ft-lbs in
testing.
Solved
Combined with the rigidity of the solid-claw and top-tensioning design, the Hansel
solution is a mount which is as durable as the bulky mounts, as ergonomic as the
single-claw mounts, and almost as quick to install as the QD mounts.
Test pictured above: legacy single-claw mount. The top red dot is a fixed laser reference point. The bottom red dot is the optic point of aim before and after torque is applied.
The Hansel
The Hansel is the first production variant built on the proven receiver interface.
ACRO / MPS Footprint
Supports popular and proven micro red dots. Other micro red dots will be supported in the
future if there is enough support for them.
Built-in Riser
The riser height supports passive night vision use and magnifier compatibility. The optic is
set about the height of a standard 1.5" riser on top of a normal picatinny MP5 rail.
Compatibility
Confirmed fitment includes MP5, MP5K, AP5, and AP5K. It is not compatible with G3, HK91,
HK93, or any receiver where the claw points do not span the ejection port.
