First time reassembling a new Mark III, and I cannot close the mainspring housing.
I am able to insert the mainspring housing bolt stop pin until it "clicks" fully in place. And, I see the rounded part of the bolt stop pin above the top of the rear receiver hole.
But, when I close the mainspring housing, it pulls the bolt stop pin out of place and I am unable to close the mainspring housing.
Anybody have any ideas on what I'm doing wrong?
Thanks.
