MOD 0 40MM GRENADE LAUNCHER. Cal. 40MM. S# 9111. Bbl. 8". An opportunity for a very rare piece of history that most enthusiasts have never even seen. The Mark 72 Model 0 "StunBurst" Grenade Launcher was manufactured by MB ASSOCIATES (MBA) the unconventional weapons manufacturer, best known for their "GyroJet" Rifles & Pistols. This is the only example this cataloger knows to exist in civilian hands. There were only 3 known examples of prototypes and none were believed to have been sold, adding to the rarity. It can be seen in the book "AN INTRODUCTION TO MBA GYROJETS AND OTHER ORDNANCE" by Mel Carpenter on page 272. It is a crank-fired grenade launcher, operating similar to the Gatling Gun. It utilizes a rifled barrel to stabilize cloth belted Stun-Bag rounds at a rate of 250 rounds per minute. NFA registry lists the manufacturer as "Accuracy Systems Inc" and Model as "429". CONDITION: It appears to be functional, missing some simple sheet metal covers and a hand crank. Exterior surfaces are painted black. The serial number "9111" is stamped inside the receiver. The inside of the top cover is marked: "MB ASSOCIATES / MK 72 MOD 0 / GYROJET / 429". Oval sticker on top cover "Stunburst". The rifling remains extremely strong.
