My old Yugo sks did it even after several cleanings.

FN49's, specifically the 8mm models are known to do this from time to time due to the mass of the one piece pin and the velocity of the bolt.
Your friend was wise to play it safe, especially if he resided in a less than friendly area concerning firearms.
We both live in Kentucky, which is one of the most "free" states in the country in regards to gun ownership.
Both times he took it out, he went to Knob Creek, which goes so far as to host a very large and well attended machine gun shoot. The notoriously surly RSO knows both of us well enough that if we're the only ones on the range he gives us free reign of it and watches TV in the RSO shack. About the only time he talks to us is to ask about an interesting gun. In any case, the SVT got his attention.
Since both my friend and I(whether alone or going together) basically only shoot on public ranges, him keeping it definitely could attract the wrong attention. With it being very much a legal "hot potato" he had too much to lose by keeping it.
It's also somewhat amusing to me that Cabelas-like most gun stores-has a pretty strict no returns on guns policy. They will usually "buy back" a gun if you decide to return it, but you'll take probably a 20-30% hit on the price. With the SVT, he walked in, said it shoots full auto, and they basically handed him his money back with no questions asked. Granted, he's a good customer(as am I)-in fact when he still lived here in Louisville we had standing plans to go to Cabelas every Monday night-but I'd still think they would probably treat anyone in that situation the same way.
BTW, a Mosin is the only true rifle I currently own. I've paired back my collection to a bunch of handguns(mostly S&W revolvers) along with a few Winchester shotguns, a couple of 22 rifles, and a 357 lever action carbine. For what it cost and the cost of ammo, it's just a great "go shoot stuff at the range" gun.
