I guess I need to circle back on this..
Safety.. Well... it looks as though the extended CZC safety needs some manner of fitting, I installed the magwell and put everything back together with the stock safety and all is well.
One thing, and I may have this dorked up as well, the main spring plug, and the cross pin for it, when I use that cross pin, there doesn't seem to be any pressure on the magwell and it will *rattle* as in, it's a bit loose... where if I leave it out.. the mainspring is applying pressure and the magwell is tight.. What is the purpose of that cross pin?
Do I have this crossed up? Is that pin needed with the czc magwell??
