mine came with 3 mags, but it came second hand.
i have seen them for sale but don't remember the price. one mag with 50 rounds last me all squirrel session. one problem i am having is ejecting a live round sometimes pulls the bullet leaving it in the barrel. i just carry a sectioned rod in a pouch for when i forget. i think this problem is just the bullets i am using which are 35g varmaggeddons from nosler. far forward ogive. i would change but they shoot so accurately and make sauce out of the squirrels.
i was really going to get rid of this upper but it is just too much fun. True Blue powder is your friend. HS7 was better but the mooks discontinued it.

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
