Full review by Bruce of BB2K Airsoft on the Heckler & Koch HK53 GBB made by VFC for Umarex... "The Heckler & Koch HK53 is an MP5 in caliber 5.56. Due to the combination of its compact design and high penetration power, it has been used by a number of special units, police and armed forces, including Brazil and Thailand.

The company VFC / UMAREX has taken on this classic and reproduced it as a GBB Airsoft.

I'll take a look at this successful 1:1 replica with you."
