With the classic MP5 high up in the radar of players, here is one they might like from Umarex, an MP5K Gas Blowback. RedWolf Airsoft TV (RWTV) give their take... "The MP5K was first introduced in 1976 by H&K as an even more compact version of the already compact MP5 submachine gun for extreme close quarter engagements in clandestine operations and close protection. With Umarex now coming out with a GBB MP5K in its original 1976 variant, Andrew takes a look at this offering from Umarex in this airsoft MP5K review."
