i just read about the 6.8SPC round and i am curious: 1) what is the likelihood/timeframe of this round becoming a new "common" caliber? (adopted by military/police organizations, arms manufacturers, the gun buying public etc) 2) what little i have read seemed like the development focus was on the AR platform with an eye to retrofitting, and i know ruger offers a Mini in 6.8, but what about retrofitting other common battle rifles? like ak, sks, cetme/hk91, etc? would there be any advantages to using one of these platforms instead of AR or Mini (cost of gun, cost/availability of ammo, short/long range accuracy/lethality, hunting, SHTF, etc) seems to me the sks chamber is part of the barrel so "just" a new barrel, bolt & mag follower would do the trick? maybe different recoil & op rod springs? not as familiar with the ak or cetme designs. . .
