Fits the Steyr M9 great.
Fits my Airsoft Steyr M9 perfectly. It took me a minute to figure out that the little button on the bottom of the mag is the spring tension release. I figured out intuitively that the spring locked back, but if you were wondering, after you lock it back and fill the mag with BBs, just nudge that little recessed black button on the bottom of the mag and it will release the spring and the follower will put tension on the BBs.
