Will this fit on a Steyr AUG A3 M1 NATO version (5.56)? Is this the most optimal Magpul magazine for it? Or is there another one designed for it? — 2 Answers

Bullpup firearms such as the Tavor do not have a 2-piece receiver (upper and lower). This may limit your access to the top of the mag for removing it. For the AR Gen 3, even though you may be able to get the CompMag in and locked in place, you may not be able to get it out. You may not be able to access the release hole. On the Gen.2, you may not be able to lock it in. Always check with a regular magazine to be sure you can perform the steps necessary to install and remove a CompMag before ordering. If you do order it and it doesn’t fit, you can always send it back for a refund, but checking first saves you some time.
