T-N.T. Studio APS-X Hop Up System Retrofit Kit for KWA MP7 Piston

The KWA MP7 GBB is a very uniquely design airsoft gun. so special and so popular in fact, that we have designed a whole new concept for it!

Not only did we design a specific set of inner barrels for the mp7 gbb, with several length options, and added our premium hop up design for mp7, but we've added an outer barrel, which will improve fixation of the inner barrel - and yet again improve accuracy and range even more.
