Agencija Alan has a stable presence at IDEX, however, for the first time in the author’s memory, in this edition, they finally took their products out of glass cabinets and welcomed the public in the booth.
RT-20 cal. 20×110 mm Anti-Materiel Rifle
The Agencija Alan RT-20 is an anti-materiel sniper rifle chambered in the 20×110 mm cannon ammunition. The name RT comes from Rucni Top, which means “hand cannon”. The most defining feature of this firearm is the recoil balancing tube venting behind the shooters back some of the gas generated by firing the round. At about 1/3 of the length of the 920 mm (36.2″) barrel, three holes on its top vent gasses inside a chamber which connects to the backward facing tube. This arrangement, together with a massive muzzle brake, tames recoil to very manageable levels in the 17 kg (37.5 lbs) rifle.
Quite surprisingly the loss of gas propelling the projectile does not affect negatively the muzzle velocity. It is still rated at 850 m/s (about 2,790 fps). More details can be found in this article by Hrachya.
VHS-2 Bullpup Assault Rifle
The Agencija Alan VHS development, iterations and deployment have been followed by TFB over the years. This interest is mostly because the rifle appears to be a well designed modern bullpup adopting original solutions towards ambidextrous operation and ergonomics. Ergonomics which were, however, recently questioned as the stock appeared disproportionately long.
The author, who stands 185 cm (about 6′ 1″) tall, handled a few of the VHS-D2, with 500 mm (about 20″) barrel, and VHS-K2, 410 mm (about 16″) barrel. Stock length appeared manageable up to about half of the buttstock extension. Further stretching to the maximum extension resulted in issues in getting a decent cheek weld.
