Raptor PKP Custom Bullpup LMG Support Weapon

  • Custom Built
  • Limited Quantity
  • Genuine Zenitco Parts

A custom-built Bullpup PKP from 'Raptor' which is made in extremely limited quantities and to a ridiculously high standard, complete with genuine real-world Zenitco/Зенитка furniture. Converted from a PKP to this 8.6kg metal monster, we guarantee there is nothing like this on your local skirmish field!

Full description


This custom built monster from Raptor started life as a PKP which is a very solid Airsoft support gun platform. They took this well established LMG and created a Bullpup design which serves to retain all which makes the PKP awesome, shortened the overall length and added a tonne of quality-of-life features which make this a devastating tool on the battlefield.

The majority of the external construction is Steel, which makes calling this LMG 'solid' an understatement. When picking up this LMG and shaking it (a hard task in itself), the only noise that can be heard is the BBs in the box mag and the stock pad at the rear. There is absolutely no Polymer to be had on the externals; everything is either Steel, CNC Aluminium or Alloy with the exception of the faux-leather cheek pad. The high quality materials and sheer amount of 'gun' in this package brings you a total weight of 8.6KG... unloaded!

The Raptor PKP Bullpup is built around an 8mm gearbox which accepts most M249 parts, making upgrading/maintenance an absolute breeze. Other key features of the gearbox are the quick change spring system which makes changing output power very quick and easy, and a link between the trigger and magazine to allow you to constantly feed BBs whenever the microswitch trigger is pulled. Other settings on the box magazine are to wind constantly or to no wind at all. There is also a socket for a remote pressure pad to wind as and when the user wants. Another feature of the magazine is a 'BB stop' which prevents rounds from trickling out the feed tube if it is not connected to the weapon - meaning no more spilled BBs when changing mags!

The box magazine on this LMG is unique in that it draws power from the 'Main Gun Battery' rather than it's own battery stored in the magazine. It is also mounted at a 45 degree angle to keep the weapon as compact as possible and to improve handling capabilities, as the magazine is not digging into your forearms.

The pièce de résistance of this Airsoft gun is the amount of genuine Zenitco parts on the externals, which are not only a talking/bragging point but offer the finest real-steel quality and will last a lifetime of abuse. Established in 1994, Zenit LLC have been in the business of manufacturing torches and other firearms parts for the civilian and military markets for over twenty years, and this LMG is absolutely plastered in trademarks from them. Included with this Airsoft gun is a gorgeous Aluminium foregrip which has an internal storage compartment, accessed by unscrewing the base. Also included is Steel constructed 20mm mount to offset the position of the foregrip by three inches, also allowing you to mount it upwards or downwards, offering the user true flexibility in terms of how you hold and maneuver this beast. The Airsoft gun comes out of the box with the integrated carry handle rail and two-point RIS handguard rail pre-installed and ready to accept accessories.

Whether you're looking for a head-turner which will get everyone talking, the closest you can get to the real thing or just want an LMG that has all the features to support it's function as a 'support weapon', the Raptor PKP Custom Bullpup LMG is going to put a big, dirty smile on your face that won't go away until the box mag runs dry.
