S&T SKS 21 BB mid-cap magazine

The S&T SKS 21 BB magazine is a polymer mid-cap magazine for the S&T SKS AEG. It is installed under the hinged metal magazine cover of the rifle, so the look of the original SKS carbine stays unchanged.

The magazine is made of polymer, and its elongated wedge-shaped body is designed for this model. Once the magazine is inserted into the magazine well, the cover is closed. A strong spring pushes the BBs toward the feed opening, and the follower extends past the edge of the feed opening when the magazine is empty. This helps feed the last BBs forward and makes the full capacity usable.
