selling my Chaszel 11" 10mm Rifled Adapter + 90 rounds of 10mm ammo. The adapter has a extractor cutout you can use if you don't want it to pop out after every shot.
Tested it, it works and is accurate but decided I don't like how heavy 10mm ammo is and don't want to carry it. Also I know its for sell currently on Ebay new for $100 but if you buy it from there you have to pay shipping + Tax and don't get 90 rounds of ammo for free. So this is a good deal.
