A number of factors led to their demise, but the big reason was that little or no military interest in the MAC was generated. MAC declared bankruptcy in 1976 and went out of business. MAC marketed a number of different weapons, but the MAC-10 (chambered in 9 mm and later in.45 ACP) and the high cyclic rate (approx. Military Armament Corporation (MAC), based in Powder Springs Georgia from 1970-1976 was the first company to commercially produce the MAC Model 10 (MAC-10).This is the company started by Gordon Ingram that designed and built the first MAC (now you know where the name came from). The following is swiped, with thanks and respect, from Scott's MAC-10 Page, an excellent resource: This is probably more info than you wanted, but you asked!Ĭan somebody explain what you mean by the New Jersey and TX macs?

You can buy a magwell adaptor and a spare upper to shoot 9mm, but if you buy a 9mm MAC-10, you can't shoot. I've used hollow points with good results in mine, but only Remingtons that have a pretty round profile. The gun was designed to have an almost straight line feed and the higher you can get the magazine without dragging on the bottom of the bolt, the better (in my opinion). I'm one of those that believes it's best to cut the mags to fit the standard catch. There is a lot of debate on whether to buy a new mag catch from Cobray to use unmodified grease gun mags or to use the standard mag catch and "cut" the magazines (take about 1/16" off of the ears of the sides of the magazine to raise it higher in the magazine well). Once they are set up right with good mags, they are very reliable, and they are built like tanks compared to the smaller 9mm M-11 Macs. They are going for around $3250 to $3750 depending on condition and accessories.
