I cant find the answer to this anywhere....

I have a ruger mini 30 stainless with a 189- serial number made in 1991. I am trying to ascertain the differences between this and the 580/581 minis. If i order a walnut stock i find online, will it fit all minis? What about the vented hand gaurd? Thanks for your input.

One thing is an improved barrel, thicker at the breach end and tapering down as it approaches the muzzle. It actually tapers only to about an inch past the wood fore stock on a ranch rifle, and then it is a uniform thickness till it reaches the muzzle. But I think it is to improve accuracy. Not sure if all parts are interchangeable though. Good luck & happy shootin'

on the new tactical model, the barrel is a full .760 past the gas block.

The main differences are the barrel (as mentioned above), and the sights.

Any Mini-30 action will fit in any Mini-30 stock. If you get a Mini-14 stock, you will have to remove a bit of material from the magazine well in the stock for a proper fit.

AFAIK, all aftermarket stocks are designed to fit the Mini-30 or -14, so there should be no need to do any fitting if you go that route.

Also, all ventilated handguards will fit any series of Mini, regardless of caliber.

not true for the Troy MCS (which would need to be machined on a mill to inlet the magazine)
or the Tapco stock. (instructions on how to inlet the mag well for a mini 30 with a file or dremel are provided with the general installation instructions)

and the sage EBR stock comes in mini 30 and mini 14 specific flavors


in addition to the thicker barrel, I'm also pretty sure that the 850/851 ranch model also has a slightly different op rod/spring interface on the breech end.
