I should note that with the mods I mentioned above, shooting my 62grn Hornady HPBT handloads, this rifle will produce 1"-1" groups at 100yds. It's as accurate as my M1A with NM sights and my 168grn Hornady handloads for it. In fact to get an M1A to shoot better, you need a bunch of money for a rear lugged Super Match or step up to a M21 configuration and the whole bit. Then you're talking north of $3,000!! Heck, my Mini is more accurate than most of my rifles, including my hunting guns; Savage 99 in 300 Savage, Winchester 88 in .308, and Winchester 70 in 30-06!
And as I said above, the mods I made, less the $200 walnut stock and the straight mags, cost me about what a decent trigger set for an AR would cost (under $250) and we all know that an AR needs a decent trigger upgrade to be a MOA performer as well. My accuracy testing was performed with the original birch stock I shortened and shimmed as well. I got the walnut stock just because it looked so good, not because it shot any better with it.
It takes my scoped sub-MOA RRA A4 firing my 68grn Hornady HPBT handloads to out-shoot this carbine. My RRA mid-length carbine, even with it's 2 stage NM trigger, doesn't match the accuracy of this Ruger Mini. BTW, the straight 20rd OE brand mags are available from time to time from CDDN at a sale price of $12.99 ea.!! Just to be safe, I swapped in a set of Ruger brand followers and the mags have been 100% reliable.
