Sero GM6 Lynx .50BMG Bullpup - Semi Auto (Black)




Sero GM6 Lynx .50BMG Bullpup - Semi Auto (Black)

One of the most intrigueing entries into the semi-automatic .50 BMG category in firearms history: the Sero GM6 Lynx. Due to the bullpup configuration, most of the weight is re-distributed to the rear of the rifle allowing for the possibility of off hand firing. This is near impossible with most other .50 BMG rifles. Thanks to the unique barrel recoil technology, the rifle's recoil is less than the other rifles in the same category. This design also allows the rifle to be transported at a length of only 928 mm. The firearm uses a unique stowing technology to achieve this. One simply presses the barrel into the reciever until it locks into place. The barrel is then stowed at the transportation length of 928mm or 36.5 inches. When one needs to deploy the weapon, simply press a spring loaded button and the barrel extends to its operating length 35.8" (overall weapon length when extended: 44") and also chambers a round.  Comes with spare magazine, spare parts (magazine spring and barrel spring), bi-pod, cleaning kit, Pelican 1750 hard case and manual.
