Great .450 bushmaster mag. - Duramag .450 Bushmaster Stainless Steel 7 Round Rifle Magazine

This Duramag C Products Manufacturing Co. .450 Bushmaster magazine is the 7 round version and works perfectly,almost. The only problem I've had is loading all 7 rounds, which the mag loads just fine,will not start loading from these MAGS until I have only 6 ROUNDS to start with in the mag. when I put it into the Magwell and lock it in. 7 rounds is too tight. With 7 ROUNDS in the mag the bcg puts way too much pressure on the round. Using the charging handle to strip the first round off a 7 round loaded mag is brutal. Way too tight. The mag needs to be a 1/4 longer. So, I use them as 6 round MAGS and they work absolutely flawlessly.
