Steve, I am fairly certain this model was NOT offered at the time A-C was still using mags, however, I have found that for mag reliability these are near unrivaled. I like to use them on my working machines, and this model is unbeatable. It also is easy to work on, kind of set up like an fmj on steroids, very heavy duty and physically larger.

just a question... what makes the OR different than an FMJ or FMX ..... I have not had too many problems with them.... when "rebuilt"....... if they are 50-70 years old, yes problems can occure. ------------- Like them all, but love the "B"s. |

| They are quite a hybrid, all the internals are set up more like an FMJ, however the body is quite similar in appearance to the FMK4 series. I just happen to like them, and for as reliable as the old FMJ mags are, these here seal up and perform better, In my opinion. I just like 'em! |

The "0" series are in a league of their own. The 0, 0H, & OR take their own components. Going out of memory, but I believe the only internal part they share with the other Mags that came on AC Tractors is the updated 2477 Coil. Haven't seen one of them in a while. Similar in looks to it's "K' series cousin, just a little larger. 30 degree lag like the "K" "J" & "X". I've rebuilt a couple over the years, but I don't think I have any cores in the pile. I'd havta' look. I remember they take that TX triangulated lower cover and end cap. They're pretty cool lookin'.......
