First off let me say this is more fun than any one person should be allowed to have!!:D:D:D These will be banned soon!!! :D:D:D:D So I picked up a CMMG .22lr conversion with one 30rd mag and one 30rd BlackDog mag. I put it into my Stag AR15 with a .223 upper and proceeded to plink away. I lubed the .22lr bolt with some CLP before inserting it into the receiver. It functioned great with Remington Thunder Bolt and CCI MiniMag. I easily put through 200rds. I had heard it was better to get a dedicated upper, but for ~$150 this little kit is really cool! Accuracy was fine for plinking at 25-50yrds. My scope is zeroed for .223 and It shot a little low with the .22lr ammo, about 2 ticks on my scope. If you are on the fence deciding whether or not get one of these, I'd recommend it for the money. ~$150 for kit, two 30rd mags from Botach Tactical.

Good news. Now I'm doubting my decision to get the 6.8SPC. Guess I'll wait for .22 uppers to drop in price.

i have one, it runs great with winchester ammo, but with remington it works for 2-3 rounds malfunctions, rinse repeat.

BlackDog Machine now has some 15 round mags that are pretty much the same profile as the 20 round .223. Makes for a better fit when firing from the bench ...

I found that using the heavier profile .22's like (40 or 60 grain) gave noticably better groups with my 1 in 9 upper.
