I just got a mini 14 182;series. From my understanding its an older rifle. Its clearly marked 223 rem. I might be able to get 1000 rounds of 556 nato for a grreat price. Will my gun shoot this? Other option is 223 steel cased. Thanks

If its marked. 223 only I wouldn't shoot 5.56 on it. There is a lot of reading on google about this.

If I'm not mistaken, the receiver stamp should say "CAL .223" (at least that's what is on my 186-series) which is not the same as .223 Rem, it's just indicating the caliber of bullet in the rifle. Ruger states that the only Mini-14 not meant to fire 5.56 NATO is their Target Model, all the others have a receiver that is actually sized more to the 5.56 than it is the commercial .223 Rem

This will make all the difference. If its marked caliber 223 then 5.56 should be fine. But if it is chambered specifically in .223 remington, there is a difference

The current Target model mini is the only one that I'm aware of specifically chambered for the .223 rather than 5.56.

There were some .222 caliber minis made years ago for export to countries like France and Mexico that prohibited civvy possession of military caliber weapons. That's the only thing I would personally be concerned about.

Best,

Not exactly, ruger specificly states that the chambers in all non-target model mini-14s are in fact 5.56mm chambers. Although the roll stamp says .223, it is in fact 5.56 so any .223 or 5.56 ammo with function properly and safely. Anything else that is marked .223, refer to the manufacturer

check page 13 (if I recall correctly) of the manual -it says it right there.

5.56 in any ".223" mini is good to go (except the Target model)


if you don't have a manual - download one for free on rugers website.
