M1 carbine conversion to 17 javilina

[6.5x53.5]

Thanks Catfish this is the kind of info I'm looking for. You have raised the POWER & COST factors which I tend to agree with,
first the universal has no gas blowback (SPRINGS) and I wasn't sure they could handle it without regular replacements. Second again I realize caseneck wall thickness is a major problem time wise. I suppose the mags lips would have to be readjusted also.
I'm still considering though. Much more like this and I'll be swayed
to enter a different realm. Thanks again Catfish!
