Proarms PAR MK3 .223rem 14,5″ (368mm) with 1:7″twist


N° Article : MK3-14-SA


The PAR Mk3 semi automatic rifle, manufactured in the Czech Republic by PROARMS ARMORY is the top high-tech weapon for both professional and sports use. The standard offer is in .223 cal (5.56 mm). Due to the universal concept of this weapon, further calibers will be launched in the near future or on special request, including 9 mm Luger, .222 Rem, 7.62×39mm, 6.8mm Rem SPC and 5.45×39 mm.

The unified platform will enable the quick change of caliber with the exchange of the barrel, bolt and magazine.

The rifle is the result of the comprehensive evaluation of knowledge of AR15 type weapons and is based on the original PAR Mk1 launched on the market in 2008.

The semi automatic PAR Mk3 rifle features high precision CNC made parts. Manufacturing tolerances are more stringent than in the standard production of this type of weapon. There is a 100 % guarantee of the interchange ability of parts from the PAR Mk3 rifle. The frame and upper receiver are from high quality 7075T6 aluminium alloy.

The weapon is designed to maintain compatibility not only in terms of individual parts but with the AR15 American production standard. The weapon can also be used with any accessory designed for the AR15. In addition, the new design allows for an overall reduction in the height of the rifle by 5 mm compare to PAR Mk1.

  • The weapon frame enables the additional installation of left or right hand controls
  • The upper receiver creates the basic contour of the weapon free of protrusions with excellent handling
  • No tools are required for assembly or disassembly of the forearm and barrel
  • Adjustable gas block (4 positions) for different types of ammunition.
    PAR Mk3 rifles therefore function with virtually all types of ammunition available on the market, including Barnaul, Wolf brands etc. Due to the adjustable amount of gas, the weapon can behave in an optimal manner with less or more effective ammunition.
