Questions & Answers
What is the difference between Tac Fire. Mil Spec M4 style 6 position stock Mar084 and the Mar085 stock. I plan to mount mine on my JTS12AK 12 gauge

The 084 uses a milspec buffer tube which is 1.168" diameter the 085 is a commercial tube 1.148" the mil spec tube is 7075 T6 alloy with rolled threads, the commercial is 6061 T6 bullet with cut threads which are shorter and weaker than the mil spec design. The commercial tube also has a 5° slant on the back of it. You cannot fit a commercial stock on a mil tube, a mil stock will fit but it will be sloppy.
