There are hundreds of .22's out there, that can shoot tighter groups, and hit bulleye. The M&P15-22 is good. But not at their level. If you just look at semi-autos, that narrows the playing field.
I have never figured out what people mean about more accurate. Does it mean the gun feels right and I hit what I aim at. Or does it mean locked down in a test machine, it hits MOA at ~ what ever range.
I think most guns are more accurate than most think. The person shooting, the sight set up make a big difference.
That said I have many .22lr semi-autos.
Of those I have four that I can shoot better than the 15-22.
Remington 552
Marlin 60
Ruger 10-22
Winchester 290
Maybe these old 1940's -1970's guns were better made. I know most are still made, but I have old.
Maybe since I grew up shooting these traditional style rifles, I just shoot them bettter. Maybe the sights are better on these old guns.
Who knows!!!
I keep working on the 15-22. It's not bad. I think the clicks on the iron sights might be off just a bit.
Guns listed by fun factor:
S&W M&P 15-22
Marlin 60
Remington 552
Winchester 290
Ruger 10-22
I have always hated the Ruger 10 round Mag. Thats why it's last on fun.
Now that I have shot it with the new 25 factory Mags.
It might top my fun list.
