I had an original Mini-14 back in the 90’s and thought it was great. The only magazine I used that worked well was the Ramline polymer magazine designed to function in the Mini-14, AR-15, and AR-180. Wish I had never sold that gun. The Mini-14 has since been redesigned and has been improved but yet still rarely do I see it referenced when defensive or SHTF-guns are discussed.
I would suppose changing marketing conditions are partly to blame for this. AR’s can be bought as low as $500 now and they look much “sexier” than a Mini-14. Accessories are more readily available for the AR. Reliable 30-rd magazines are plentiful and inexpensive. Of course much of this goes for the AK as well.
There are many other firearms out there besides the Mini-14 that may not get the attention they deserve as a viable SHTF-gun. Reasons may be cost of the gun, cost of the ammunition, lack of awareness from the masses. It may also be the overwhelming portrayal of the AR-15 as THE gun to have. I likely play a role in that. Guilty as charged.
