Hera Arms Triarii allows an end-user to fit or remove an unmodified service pistol into the chassis stock to allow carbine capabilities with a pistol. No tools are required to perform this, a robust lock and slide system allows this operation to be completed in around 4 seconds. This will also work on airsoft pistols based on the live fire models.
 
Manufactured in Germany, machined from high grade aluminium, the Triarii platform also allows the fitting of accessories such as iron sights, optics, weapon lights and laser designators. With an improved sighting radius and/or optics, coupled with the stability of a shoulder fired weapon this increases the probability of first round hits in any engagement and helps extend the effective range of a pistol.
 
On fitting to the Triarii chassis stock, the fire controls and operation of the pistol remain unchanged.
 
To allow for use by individuals equipped with ballistic helmets, the angle of the stock is easily and quickly adjusted to suit the user with an Allen key. 
 
The unit can be supplied as a chassis only allowing the end-user to add the stock and iron sights desired, or more commonly selected is the ‘RTU’ Ready to Use version which out of the box is supplied complete with a forward pistol grip, back up iron sights and an M4 retractable stock. This can also be fitted with a side folding hinge allowing for a more compact package.
