Dump1567 Posted June 17, 2007 Share Posted June 17, 2007 Just picked-up a used M3 with an AT (88) date code (no 922r issues). Serial # is 066xxx. I had a couple of questions for the experts. Is there any problems with the older models I should be aware of? I figured out the 7+1+1 loading, but what is the purpose of the little latch that releases a round onto the loader lifter? Why would you want to release a round into this area? It has the 1 piece 7 round tube. Does this unscrew from the reciever to replace the mag. tube spring? Or is there an easier way? Thanks.
