Hello All,

Glad to be here and I hope I am posting in the right category.

Are these a waste of time? Will I be able to get some nice grouping at 50 and 100 yards?

Id like to get another gun, but the wife has some limitations when I have hobbies like golf and photography and now guns :p

Thanks for your feedback.
 
I have the CMMG kit. Accuracy is middling at best, maybe 4" groups at 50yds. The problem is the bore is slightly oversized for the .22LR bullet and this reduces the accuracy. It is really more of a fun blaster for cheap CQB practice and a great way to introduce new shooters to black rifles. That said, the money is well spent, IMO. I have shot thousands of rounds through mine and saved far more than the cost of the kit while having a ball blasting away with 25 round mags.

I've looked into the same thing, and it seems that the general consensus is to go with a dedicated .22LR upper, rather than a conversion... IIRC, the conversions aren't cheap, and performance will be much nicer with a dedicated upper. Plus, then you can always add some extra parts and have a complete second rifle... I mean, your wife can't mind that much if you slowly acquire more parts for a second rifle, right?

Have you tried posting in the Black & Green Rifles subforum? They might have some good recommendations on conversions vs dedicated uppers, and which brand to look for.
 
The dedicated uppers will be far more accurate than just a conversion bolt carrier group setup. The problem isn't just the slightly different sized bore, it's also the twist rate. Trying to spin a little .22LR bullet at 1:7 when it would like something in the 1:16 range will cause accuracy issues too. Search the Black Rifle section archives for more info, but it comes down to what you want from it. We all have different needs. For me, I use a local indoor range that isn't certified for .223 centerfire, so if I want to have some AR-15 fun I'll toss in the .22LR conversion bolt setup and blast away. If I want accuracy then I have a dedicated .22LR target rifle I'll use instead.
 
If you're using a BCG conversion kit pay attention to cleaning out the blowback tube. If the tube gets gunked up it may cause cycling issues for the real ammo.
The stainless CMMG kit runs well by simply polishing the two guide rails. Or shooting off a thousand rounds will get you the same results. Also, do not over lube!

Just get an M&P 15-22. That's what I did. Yeah it's ANOTHER rifle and maybe harder to justify to the wife, but hey, it's ANOTHER rifle and price wise you won't be too far off a conversion. Plus you get something that'll be accurate, very reliable, and the same controls as your AR (including a functional bolt release, something most of the conversion don't have).

Don't forget those fantastic 10 round mags. Are there any aftermarket rifle mags for it yet?

I have the Chiappa upper as well ... no issues no problems. Good groupings ... It's polymer construction but since it's still restricted it's fine for making confetti at the range ... in fact I used the Chiappa upper / Norc lower to introduce my 12 year old daughter to shooting and she did very well with it ...
 
My Colt HBAR came with a Colt Conversion Kit back in 1990. Accuracy was minute of popcan at 50 yards. Sadly, taking it out in the bush is now a distant memory.
