This gun is sold but can contact us to build one on order. 

This is our clone of the famous MC51 in 7,62 Nato (.308)
The original gun was requested by the SAS for counter terrorism operations in Northern Ireland where plainclothes was mandatory and a short gun in rifle power was necessary so the operators could defend themselves till could be extracted.
HK never developed such a gun for years (when they developed the HK53, exactly the same gun but in 5,56 cal.) and FR Ordnance asked the collaboration of Fleming Firearms which was developing these guns for the US Marked. As far as history goes Fleming developed 20 of these guns which then officially entered into legend. A former Special forces member who now resides in the US told us that he used one of the original guns in 7,62 and 5,56 in Northern Ireland , which were particularly appreciated for the short dimension and the powerful fireball and roar which could keep an hostile linching crowd at distance till extraction could be obtained (sometimes required hours).

To keep prices at reasonable level we start from a Cetme parts kit (perfectly compatible with G3 parts) and we manufacture the receiver, install a new RCM barrel and trunnion. We also install original G3 sights and paddle mag.
Then the gun is tested for at least 2 magazines before being finished in KG Cote HK Flat Black.

See a brief history of this gun here:

This gun is not for the faint hearted; the roar and fireball are really impressive and a show by themselves. You can be sure you will turn some heads at the range sporting this monster.

Each of these guns has a paddle mag installed as the original. The gun is equipped with a fixed brace and registered as a pistol for the ultimate truck gun. Can be easily converted to SBR - once paperwork is done - simply changing the tube from pistol to rifle or installing a stock endcap (available from us as a spare part).

This gun will be problem free and perfectly reliable out of the box because we walk the extra mile of testing the gun before shipping it.

We don't offload reliability problems on our customers, we solve them before selling the gun.

We are a small gunsmith building these guns one by one.
