Congrats on a quality milsurp! I easily fall in love with the full aka Mannlicher stock configurations! Yours, exemplary of ringing my chimes! The "odd" barrel length would be right I believe for a Model 1894 Swede Carbine, made up principally up to about 1916 or so. A great chambering and those Swede '96 series renown for quality! A short barrel milsurp making sense.

My opposite extreme lived! As "seemed like a good idea at the time..." Sako Mk V full stock carbine, conjuring a truly good price point wise; BUT... 20" barrel in .375 H&H Mag... An 'all factory' flame-thrower X lots of "Ft Lbs push back! Marginal 'in prime' days, more in Arthritic Eighties! But would I part with it... NO!

Enjoy that nice 6.5 great chambering edition!

Best!
