A Universal M-1 was one of the first new guns I bought in 1974. $170 OTD. It was junk and the magazine retaining latch and mag well were junk pot metal that became so sloppy that mags would fall out while firing! I had it at a gunsmith's shop for repair and all the guns there got stolen. He bought me a brand new replacement Universal. I never fired it and replaced it with one of the 2 IBM's I have now!

I also had a number of old model mini-14's in blue and stainless. They shot terrible!!! Any AR-15 that was assembled half way correct will out shoot them all day long!

Unsolicited advice: Sell the Universal and the mini, for as mush as you can and still make a sale! Keep the AR's and the M-1 ammo and find a GI or mil-spec M-1! You didn't say what size your mags are, most any 15 round mag will function until damaged, after-market 30 round mags are junk from day one!
