Agreed, I would get a delicated .22LR upper...it is better
That would have been the cheaper route but at the time I didn't have the money for a complete upper. So, I had to buy the parts serperately as cash was freed up.

Just get a dedicated... There pretty much the same price as an upper or convershion. Plus you get another gun!
Buy or build a dedicated upper with an appropriate twist barrel for 22LR.
Using a slip in conversion kit you are putting a light slow bullet through a 1:7-1:9 twist barrel designed for 55-75gr bullets going around 3000fps so accuracy will probably suffer. My CMMG kit was not reliable unless kept really clean, if you shoot anything other than jacketed 22 you will eventually plug off your gas port with lead and then it will be unreliable or just not cycle when you shoot .223.
My $0.02
YMMV

i had a spikes stainless .22 conversion and the accuracy was so bad. only good for pinking within say 25 metres. it was like water coming out of a garden hose.
i have a cmmg dedicated upper now...its okay except for the fact i had to do a little work on it to get it to cycle reliably. there is this WASP coating cmmg like to put on their stuff. had to strip that crap off to get it to run well.

Where are you finding these uppers? The only .22 dedicated upper I can find is a $550 CMMG from Questar, and conversions I found are $220-$250.

How is the accuracy of the cmmg upper?
The .22LR conversion bolt in my 1:7 twist barrel is like the rifle is throwing the bullets at the target with its wrong hand.
the accuracy of the upper is decent. i think its a 1:12 twist...its light years better than a conversion coming out of a .223/5.56 barrel
That price doesn't sound too far off. Frontier sells them but it doesn't look like they have any in stock right now. There are probably a few sponsoring dealers that have them, you'll have to do some surfing on your own. I thought they were around $450 for a new CMMG upper. That may have changed but I find Questar usually has a little higher prices than others so it pays to look around a little.
Also watch the EE for used ones. I was looking at them a while ago and there was one for $400 that was hardly used.

What's wrong with polymer? Light, strong, light.
It's the future of firearms. Almost every manufacturer is using polymer parts now and they aren't blowing apart. This isn't Chinese plastic, it's engineered reinforced polymer. Much different. Do Glocks, HK's, KelTec's etc fail because of the polymer? Nope. It's just a .22LR anyway, not a 300 mag or something where you would need to worry about it.
All the polymer guns I own or owned have always had metal rails molded into them where needed for strength and where things rub together. I'm sure that this one is no different and would last for many years without problems

^guess i'm just old school =)
Nothing wrong with that, just don't count them out till you give them a try. Cars were new at one time as well and I bet your not riding a horse any more. Computers were new at one time and I see you have adapted to them as well.
There are a lot of really great guns out there that have a lot of poymer in them. My Kriss Vector and RFB are great guns with lots of polymer but they are steel where they need to be.
Being in the Black Rifles section you might want to give polymer a chance since even the AR uses polymer for the handgaurds, grips and stocks. You can even buy polymer lowers for the AR now.
