If practice for an AR is what you are after, a Rimfire upper for an AR is what you seek.
Like these two.
Complete uppers can be found at RighttoBear.com. They are rebranded CMMG dedicated uppers and parts, have zero accuracy issues, and I like them!

Cheaper than buying a new rifle, and still practicing with the actual trigger one would use in competition.
And a thousand times better than a S&W15/22, which should be much better than everyone’s I’ve shot was…
The only problem is they come and go in stock often. I had a notification on mine. Got an email, bought one, went back to look at more and they were gone. Got another email a week later, so they get them pretty regularly.
I see they are not as inexpensive as they were once…But they
are well worth it.
As well, because it’s an AR, build it.
I had to say. You know you’re gonna hear it.

Beyers Barrels has match chambered, collared barrels that are tension sleeved, like a Ruger. They can be had with a faster twist and many lengths. My pistol has a Beyer barrel in it and it’s every bit as accurate as the mirror smooth CMMG nitrided rifle barrel.
A collared barrel and non-conversion rimfire bolt kit, a few Blackdog magazines and all the normal AR parts assembled the same, will have you practicing the right way.
You can’t practice motorcycle racing in a truck…
