We used them in the military, if it is the same design. Worked OK.

I have a DPMS dedicated 22LR upper.
Reliable and accurate.
I got it for around $300
It was designed from the ground up as a 22lr, and not shoehorned into a standard machined upper, it has a very 10/22 like bolt.
I have heard that 22lr fired through a standard AR bore is not the best for accuracy, but good enough for closer range plinking.
I thought hard about getting a conversion, and decided against it. I also looked into many different 22lr uppers. Ended up with the DPMS not only for the lower cost, but I also liked the design better.
I have a strong suspicion that it is made by Nordic Components, a variant of their dedicated 22lr upper... Though they have moved on to a gen 2 version under their branding. Nordic makes good stuff.

.22 LR Conversion kit for a .223 Rem Upper
After selling off a lot of older, pre-ban AR-15s, I ended up with an old upper missing the complete Bolt Carrier Unit and Charging Handle.
Had always wanted to to try a ".22 LR Conversion kit" anyway.
So, both problems solved using the .22 Conversion in this rifle and keeping them and another lower together as a dedicated .22 LR Rifle.
Don't know the history of the upper but it has a very slow twist so it works far better than a 1:7" or 1:8" twist barrel.
Function is 100% and accuracy out to 25 Yards is very good.

Yeah, I got it on sale it was around $325 after shipping I believe.
I see it running around $375 now.

All the conversions I've seen or owned you can remove the part that fits into the chamber with a part thats called a collar and replace the barrel with one that is chambered for 22LR. These barrels come in a normal rimfire twist. I took a 1 in 9 / 5.56 barrel and cut it short behind the gas port for a pistol and it grouped just fine and really made the 60gr.SSS come alive.

I bought a CMMG .22LR upper about two years ago to use as practice for high power service rifle matches. I think it was about $300. Has been flawless, even using a pinch tool to single load off the magazine. Works with any lower I have put it on, Rock River, PSA, CMMG, even a couple 80% I milled myself.
"conversion unit" vs. a "conversion"
"All the conversions I've seen or owned you can remove the part that fits into the chamber with a part thats called a collar and replace the barrel with one that is chambered for 22LR."
Well, you need to keep looking!
A "conversion unit" vs. a "conversion", all you do is remove the BCG (bolt carrier group) install the .22 conversion and you are done!
NO "collar", NO BARREL REPLACEMENT....

My DPMS dedicated rifle has a lower that will function on any AR upper. The dedicated upper is 100% reliable and accurate built as a M4 look alike, after many thousand rounds it looks and prints as new and the barrel twist is correct for the LR bullet (1/16).
The conversions work but are bouncing a lead bullet down the barrel of your home defense weapon.
