it does, from what i gather i need to replace the buffer assembly, with heavier buffer, spring, and maybe a different tube. i am unfamiliar as to the different impacts a carbine/ rifle buffer system would have, and i will honestly defer to your opinion on this. which would you recommend for my build? i also get why i may need to re drill my gas port. on the gas aspect, is it worthwhile installing a armalite/ar10 gas tube, because the one i currently have is definitely for a ar15.
