Does the 189-24xxx series Ruger Mini-30 come with the tapered barrel? I hear the later series use .310 barrels, but have heard the earlier versions came with a .310 that tapered to a .308 at the end. Thanks for any replies.

you are confusing barrel od with actual bore size. it will shoot any 7.62x39 ammo you choose to feed it. the barrel taper is irrelevant. they don't care for the cheap com-bloc ammo because of the hard primers.

The new barrels which are tapered from the gas block to the muzzle is a heavier diameter and more accurate than the earlier straight barrels.

All of the new ones are .310 and have been since the early 80's. The OP might be talking about the forcing cone that Ruger used in the ones prior to that, it could be called tapered I guess since the bore goes from .310 to .308.

Ruger has a section on thier site that details the specs by the serial number. It doesn't say which serial #'s got the old .308 barrel but you can go by the dates and the change was in 83-84 IIRC.

the OP is referring to a longer tapered throat used on early .308 szueeze bore Mini30's

Best I can tell, my gun was made in '89. First guns were made in '86. Just trying to figure out if mine has the tapered throat with an actual .308 bore at the end. Or is it .310 all the way through?

The switch was probably made in 92. Ruger won't give an exact date, I gather, but they will tell you if call and ask about your gun.
Yours is probably .310 down to .308.

JohnMc is correct about the time frame. It right about the time that Clinton enacted the AWB. And that's when and why I bought mine.

Don't know why I was stuck in the 80's, I hated the 80's.
