ARWEN 37S Introduction

The ARWEN 37 and its siblings are the first multi-purpose, multi-shot weapon system to combine light weight, high accuracy and the ability to fire up to 5 shots before reloading.

  • CQB - The ARWEN 37S' shortened barrel and no stock makes it the ideal hand held (not shouldered like the 37T) weapon for CQB operations
  • Can be fired single handed - similar to a pistol
  • Can be fired using the Tibor Tactical 3 point HiLo Tactical Sling 
  • High Accuracy - Rifled barrel ensures accurate flight of projectiles
  • Safety Features - Double action trigger plus fully ambidextrous manual safety
  • Light Weight - The ARWEN 37S is made from light weight aluminum and polymer materials
  • Reliable, Light Weight Rotary Magazine - with minimal rotational torque
  • Semi-Automatic Function - Each round is automatically indexed at top dead center
  • 5 Rounds in 4 Seconds Rapid Fire
  • Fires all original 37mm ARWEN and ARWEN compatible ammunition types
  • Easy to Reload - The ARWEN 37S has a rotary magazine with a 5 shot capacity. The ARWEN 37S can be instantly topped up or exchanged with different ammunition types while being held in the firing position
  • Instant Ability to Check Magazine Status - The ammunition in the ARWEN 37S is visible from the outside of the weapon and the number and type of ammunition can easily be seen
  • Easily Field Stripped - The ARWEN 37S can be field stripped in seconds for thorough cleaning and inspection
  • Fully Ambidextrous - Can be fired with right or left hand without modification
  • Minimum Maintenance Required - Certified Armourer courses available
  • Made in Canada 

The ARWEN 37S weapon is light: 2.72kg (6lb) unloaded or 3.35kg (7lb, 6oz) loaded with 5 AR-1 baton rounds; finished in matt black and, because of its design, is very safe. It is very easy to use, being suitable for right or left-handed operators of any height or build. Exposed parts are made of anodized aluminum alloy and plastics, which are unaffected by damp environments; where steel parts are necessary, they are in shielded positions where they can be kept lubricated and protected from rust. Routine stripping, cleaning, lubrication and reassembly are easily done with the simple tools, brushes and cloths; cleaning brushes and lubricants can be provided.

A carrying sling is provided as standard and an optional carrying case can be supplied with each weapon. ARWEN 37S is easily loaded from a cartridge belt carrying two detachable fasteners which are compatible with most military style webbing. The special style of 37mm ARWEN ammunition makes an important contribution to its weight and space-saving design. The cartridge case safely contains the propellant gases without the support of a chamber: This feature contributes greatly to the simplicity of the system. When a round has been fired, the spent case is ejected to the right. Cartridge cases and batons used for training can be recovered and refurbished for re-use, keeping down training costs. 37mm ARWEN projectiles are spun by the rifled barrel, so that they are extremely accurate.

How ARWEN 37S Offers Security in the Less Lethal Role

ARWEN 37S is the first less lethal CQB weapon to combine lightness, high accuracy and the ability to fire up to 5 shots without reloading. The ARWEN 37S has the option to quickly change the ammunition type of the first round to be fired. This offers the operator a choice of tactics and a level of response unmatched by any other system. The ARWEN 37S provides you with the most effective means of less lethal projectile deployment.
