If you own an AR45 pistol or are dreaming of building one you most likely want to make it the shortest length you can. After all it's a pistol. The AR15 industry has blown up with the new PDW stock for rifles and SBR's. One of the most popular manufacturers of a version of the PDW stock is MVB Industries. MVB has now taken the compact system in the PD stock and designed a compact buffer tube for the AR Pistol crowd with the MPK or Micro Pistol Kit. The MVB Micro Pistol Kit (MPK) comes in a complete package for your AR pistol. Like the MVB ARC stock, it gives you the opportunity to use any mil spec .45 ACP BCG you want.
This pistol kit is the absolute shortest available for the AR15/AR45; only 4 – 7/8″ from the rear of the lower using the same patented buffer and spring system of MVB's popular ARC Stock.
