I seen a bolt action rifle in an antique shop today in a locked case. It had a plum shaped bolt(handle) and a side sling loop on the stock. The bore appeared to be 6,5mm and its a carbine. The rear site appeared to be a blade sight same as the front but i didn't get a close look at it. It wasn't a normal looking mauser type gun like a swede or a chilean. There was a bayo mount that looked like an upside down "T" lug on the bottom of the front ring. The guy had it marked $275. I didn't ask any questions because i left my C&R ffl copies at home. I always keep copies with me but my wife washed my wallet a few weeks ago. Of course i find interesting looking stuff now right? I'm just not sure what it is. How many different rifles are there in 6mm or 6,5mm?
