I just got off the phone with Mossberg-the mother ship. they no longer make the single action arm assembly. However, the dual action arm assembly is generally in stock for the 20 gauge. they had none in stock but said to call back in 3 weeks. I would have to take one arm off, he suggested a gunsmith to do the work. Is this something I can do? I am pretty skilled in a lot of areas-my wife says that I can fix most anything and so far she has been right. He also said that right now all parts are going into building shotguns and none are for parts replacement since the market is so hectic.
Alert: I just found a single arm action assembly in 7 3/4". Is this the size I need? or do I need the 6 3/4" tube? thanks for all the information on this...it is extremely helpful.
