Maybe you need this:
I have a 1975 HK91. I recently picked up a G3 bayonet and bayo adapter, and found that they do not work.
The hole in the sight base of the 91 is at 3 o'clock looking toward the muzzle. On my sp5k, the hole is more at like 7, or 8 o'clock. As I recall, on my previous 91 and 93, it was the same as the sp5k, but I don't have detailed pics to confirm.
Own: HK91, SR9, SP5k, G36k, HK416, P30L, 2x P8, 2x P8A1, USP9
Future: Done, until HK comes out with something new & nifty. Might start building an FNH collection.
Presume you are referring to this:
NOTE: "appears" to be tapered, so the older adapter will not work.
On the straight cocking tube, the handguard pushpin simply rests on the triple frame, while the tapered cocking tube has an extra "hanger" welded onto it for the handguard--- make certain which one you have before you purchase.

Can someone post pics of a straight tube in this area?
I'll post pics of my '75 later today.
Could not find a side-by-side comparison, but you can tell from here:
Straight cocking tube fits the triple tree hole exactly, the tapered or coke bottle front is smaller allowing the barrel to free float. The coke bottle style has the hanger and pin hole for the forearm as well. Tony's posted pics didnt work for me, if you need a pic Ill dig out mine and get a pic for you.
Yeah, this thing has a tapered tube. So I guess no bayonet for me.
That's kind of a bummer.
