10 round 5.56mm stainless steel magazine in a 20 round straight body. These magazines are modified by the factory to only allow 10 rounds to be inserted so that they are legal for purchase and use in California. these magazines are stainless steel and Black Mar-Lube finish, chrome silicon spring, and anti-tilt follower.
The magazines are brand new straight from the factory, however, like any dry film finish magazine the finish will show wear from production, testing, and shipping. This finish wear does not affect the functioning of the magazine.
