I had a Mini long before an AR. It’s a fun gun at the range, no doubt, but in the field I struggled to acquire targets quickly. Mine is an old one without a good way to attach optics (I tried).
I have good mags for the Mini, both 20 and 30 rounders. It doesn’t jam. I can ping a 8” gong offhand at 100 yards all day. But for more demanding shots the AR is way more accurate.

The scout rail ultimak makes helped me attach a sig sauer romeo 5 dot, which helped me with target acquisition FWIW.
