Descroption snagged from Arnie's:
"Owners of the Craft Apple Work’s Benelli M1014 beware that this is not just the spring powered CAW Benelli, but with Yuji Gun Factory’s modified Maruzen M1100 semi-auto gas cartridge blowback model.
Boasting G&P’s Benelli folding stock on a full-size M4 custom (CAW 1014), this is every shotgun user’s dream. With the help of the gas cartridge ejecting system found on Maruzen’s M1100 series, you too can enjoy the realism of loading the cartridges (7+1) and firing on semi-auto leaving the field nothing but spent cartridges on the floor. The operation of this gun is exactly like the Maruzen M110 shotgun, in which gas is loaded into the grip, shells are inserted, and the bolt is charged prior to firing. The gun fires on semi-auto so there is no pump-action on this model. Yuji Gun Factory has been always known for his high-end customs of most Marui-based shotguns like the M3 and SPAS12 with pump shell ejection) and blowback systems and other highly rare customs not available anywhere.
Price for this custom gun is ￥89800. Folk’s in Japan I highly recommend you see his guns."
