Is there a way to tell if a bolt carrier group for the HK91 is semi auto or full auto? I see advertisements and claim their F/A but what are the differences and how can one tell the difference bewteen the two? Thanks
Solutions are not the answer.

Thanks Griffon. I thought there were more differences then that, like the bolt was made a bit different or the metal was treated or something. Can't remember now.
Are there any issues with running the FA carrier in an SA gun? Are there any ATF issues?
If there are issues, is it just a matter of maching the slot?
correct me if I'm wrong, but a F/A bolt carrier won't change anything unless you use a F/A trigger pack. The F/A portion has to be removed from it. As long as the trigger pack is clipped and pinned u should be good.
Its not phyiscally possible to have the F/A parts in clipped/pinned trigger group, there is no room, is that correct?
What are the primary differences in the PSG-1 bolt carriers and the standard G3/PTR/HK91 carriers?
I just ordered a pair of the Rhinemetalls. I know there are the forward assist serrations on the PSG groups, but is that the extent of the difference? I like the fact that the Rhinemetall carrier is one piece, I'd like to have the forward assist serrations cut and then the carrier EXO coated.
Additionally, will I need to buy the MSG and PSG bolt heads and extractors for my conversions?
But Rheinmetall carriers aren't truly one piece. They're still welded together, just in different locations. On the standard carriers, the entire top tube is one piece, and is welded to the main body of the carrier. On a Rheinmetall carrier, the length of top tube that is the same width as the body is integral with the body, but the tube extension is then inserted into that top tube portion and spot welded at 3:00, 9:00, and 12:00 near the back of the tube area. I like them as well, but it's just a different method of mfg. It's not like you'll ever see a top tube break off of a standard carrier.

Are the Rhinemetall carriers slightly heavier than the standard bolt carriers? I'm hoping to pick up some extra weight in the carrier group with them. I don't want to venture a guess as to how much difference there would be, but I am curious.
