Quote: Sevens, very classy rifle, you should be pleased with. I believe the hole in the TG is for bolt disassembly instead for a sling swivel.
The hole in the TG is for a sling, the bolt disassembly hole was in the butt stock ( that big disk in the middle of the K98 butt )or with the pressed steel cupped buttplate used after about 1942 there was hole through that which did the job.
