Where did you get your fireing pin from? I had some work done on my Carbine. It's very smooth now but on occasions it has a ftf. I've read where this is a problem on the Brownings, and now that I have the rifle too, might be something to look into. Haven't fired the rifle yet, but it is stiff.

Its a couple years ago and one of my failings is I dont write stuff down
The Browning 71 firing pin comes in three pieces with a little spring loaded latch affair that locks into the short centre section - I guess to prevent an Out of Battery Discharge - when it goes haywire you get a FTF - I didnt investigate a whole lot, maybe a good clean would have worked till next time - I just went online and found a picture of a real 71 firing pin - Its solid like old ones are - I figured from that we didnt really need all those little bits so I took em out and put away in a little bag with their name on it .
The front portion of the pin (the striker bit) has a return spring - I left that as is - (although I believe the rifle would function correctly with it out)
theres a photo below of the leftover parts - you can see the small (black) round bit that is the centre part of the firing pin and the notches in it where the little silver latch thingy engages - then there are two little pins - one is the latch pivot that fixes that part in the bolt - other is the retainer pin for the latch sptring (I used the spring for a ruger style hand spring in our army colt so the spring is missing from the pic - but you get it - about 1/8th diameter and maybe half inch long)
So that black piece with the notches in it goes into a counterbore in the forward end of the rear half of the firing pin (the half the hammer impacts on) I made a sollid replacement on the lathe and fitted it in.
This is where the memory fails - how did I fix it in? No idea! I know I would not have soldered or brazed it - so its either a neat floating fit OR if the other piece had a retaining pin I would have used that OR red loctite if I thought that appropriate
so now we have a two piece firing pin - it all works as its sposed to - the rebound spring keeps the firing pin to the rear against the hammer face when its on half cock
also the firing pin begins to retract away from the primer immediately you move the lever - that is proper lever retraction NOT just the rebound spring so to my mind there is still no chance of an OBD.
So its all good - works nice - have not shot it much since - cant see a problem in what I did. Making a full length new pin for one of these or a 86 or 92 is a major undertaking for a hobbyist with hand tools.
Lawyer stuff has a purpose I guess but guys take these guns and chase things that eat ya - if the first FTF happend on a charging Grizzly or a cranky Bull Moose .... i guess the lawyer is ok and the undertaker gets some more work
