Had the mag drop out 2 or 3 times in my younger days. You learn a lot from these lessons. 2 problems I found, both mine. 1) as Ol TOM says above, listen for the click when inserting magazine, and always double check it. Those black clips are hard to find in the dark. 2) My '06 760 holds 5 rounds, although the mag will hold 5, it wont stay in the gun with a closed bolt and 5 in the clip, learned that the hard way too. I quickly became very familiar with every part of this rifle, it's my favorite and first choice of all I own, only cause it's my first rifle given to me by my dad 30 years ago. Probably a lot better choices today, but you don't get rid of an old reliable friend.
