Brügger & Thomet (more commonly known as B&T) makes one of the most unique products used in law enforcement around the world. A perfect example is the B&T GHM-9 G submachine gun, a licensed replica of which was made by Lambda Defense.
The replica is based around standard Tokyo Marui GLOCK magazines and its derivatives. The replica is made of polymers, steel and aluminum, both externally and internally. Additionally, three versions with different stocks and barrel lengths are available at the manufacturer's website, despite the first announcement of just a version without a stock, a rear rail for mounting one and the shortest version of the barrel. The planned versions include one with an extendable stock similar to one known from the MP5 and two additional barrel lengths.
The replicas are now available for purchase.
