My LGS gave me this Kaboomed Egyptian FN-49 today. It's a CAI gun. To add insult to injury it was the second time it had kaboomed. The owner had it "fixed" and then it let loose again after a few rounds. I think I would have quit the first go-round.
The funny thing is when I took it apart I could not find any reason it let go unless it fired out of battery. The gas setting was fine. The only broken part was the rear of the extractor when the kaboom bent it out and cracked it.
When it let go (8mm Romanian surplus) it looks like all the force went straight down and bulged the mag and in turn stretched the sides of the mag well in the trigger group/guard assembly. I got the mag pounded back in shape and bent in the sides of the mag well opening true.
One thing I did notice was that the stock was repaired poorly after it let loose the first time. It would not have taken but a few rounds to have split it again. It is one of those beech CAI replacement stocks and it split darn near perfectly in half.
I could fix the stock but why bother, I'd never-ever trust the rifle. The guy got away twice with nothing but hurt feel-goods and a lighter wallet and I don't want to be the odd man out with a injury.
I was thinking of parting it out or selling it as is but I think I might make a gun lamp out of it instead to preclude anyone getting bad parts or crazy ideas of trying to shoot it.
I glued/screwed the stock back together well enough to start making a lamp of it. It will be real easy to do.
I had a slam-fire once, in an 8x57 Egyptian FN-49. I was slightly injured by small brass particles that cut my forehead, and my glasses were scratched. The rifle was damaged, wood blown out of the bottom around the magazine well. I was using some relatively anemic factory loaded 8mm Mauser hunting ammo someone had given me to use up. The rifle "doubled" the second shot which was a slam fire nearly immediately following the first shot. And apparently the bolt lugs had not fully locked, the rifle firing out of lock and the case rupturing. Previously I had used only Milsurp full-power ammo. FN-49's are known to have firing pin problems, breakage which can leave the forward part of the firing pin extending through the bolt. I had no parts breakage, and the firing pin seemed to retract OK. I can only assume the slam fire had something to do with the soft factory primers, but I'll never know for sure. I felt very fortunate to not have been hurt worse. I don't want to repeat the problem, so I am very careful about high primers, and use only CCI-34's in my reloads for semi-auto rifles (Garand, M1A) which I shoot often in local matches. I don't know how an AK would handle an out-of-battery slam fire any better than anything else.
Hey all,
I recently had an 'out of battery slamfire' in my, two piece firing pin, FN49. I had made 8mm Mauser ammo from milsurp 30-06 cases. The dimensions of the cases (30-06 and 7.92x57mm S) are identical at the base and only need to be cut down to the correct length, sized and trimmed. The problem with making your own ammo for the FN49 is that it is a very robust firing mechanism that will ignite a sensitive primer before the round is seated in the chamber. I was using CCI 200 Large Rifle Primers which are reasonably sensitive for bolt action rifles and, I have found out, too sensitive for semi auto rifles. Even though I've used these primers for years in my FALs, and WASR AK47, I'm going to stop and use CCI 34 Large, 41 Small, or milsurp in the semi auto rifles.
The 'oob' slamfire caused the receiver and bolt carrier to become a bad fit! I searched (Google) and found a gunsmith in Missouri who could fix the rifle. His name is Guy Snelen at AMG International in Humansville, Missouri. He repaired it, test fired it, and sent it home to me. If anyone needs a good gunsmith, get in touch with Guy.
op's is 8x57. not sure if you knew that. good info on firing pin. i never knew that.I would break my hand, reaching for my wallet, to get a FN 49 in that nice of condition in 30-06. I don't remember the exact date those came into the country, but I have a memory of seeing one in the 1970's. Could have been another caliber though. The 30-06 version was never plentyful.
If you do get it, be aware of the slamfire problem with these things. Do not, under any condition, fire "commercial" ammunition in one. That is ammunition that does not have on the box "M1 Garand"

note the lower velocity of the mil spec type ammunition

Besides the over pressure issues of "commercial ammunition", my primary worry is the slamfire potential of FN 49's. Which is real, and catastrophic to the rifle.

I am buggered that a link I had to an article "collecting and shooting the model 1949 FN semiautomatic rifle" at thisoldrifle.com is busted. The site must have gone away. Anyway the link showed how to remove the firing pin, and strongly recommended replacing any one piece firing pins with a two piece firing pin. Apparently the one piece firing pins would break.
But my concern is about sensitive commercial primers in this mechanism. There are reports of out of battery slamfires where the post ka boom analysis indicated the firing pin was just fine. The only allowable primer to use in this mechanism is the CCI #34, which is an American mil spec primer. Hopefully that is good enough, but FN may have required an even less sensitive primer than the US #34, but that would not have made sense if the buyer wanted to use US surplus ammunition.
