I'm currently saving for a CMMG dedicated .22 upper, but the .22 conversions are significantly cheaper and will get me shooting sooner.
Is there any significant reason to go with the dedicated upper rather than the conversion? I've heard that some of the conversions are hard on lower receiver parts (hammers and pins). Is this also true for the dedicated uppers? My current plans are to mount a Burris FF2, and Magpul MBUS sights to the upper. This will allow me to dial in my sights for the .22 round and keep the lead/ wax debris out of my 5.56 upper. If you have any thoughts, please feel free to chime in. |

Dedicated uppers are more accurate since the barrel twist actually matches the 22lr. Plus with a separate dedicated upper, you can always buy another lower down the road and leave it as a complete rifle.
Conversion kits are fine if you only plink within the 50 yard range and are quick to remove when you feel like putting the ear plugs back in. :) |

Quoted:
With a dedicated upper you have to buy a Mag too and is that it? Just the upper and the mag and no other mods? Most dedicated uppers come with matching mags...yes, that is all you need with the exception of sights if they are not included or a scope...and a complete lower of course. There are so many 22lr uppers to chose from nowadays it's unreal. When I purchased mine, all I had to choose from was a CZ-22 upper and a Oly Arms 17/22...or a conversion kit. I tried the CZ first...very heavy and it had chamber issues. I returned it and picked up the Oly. The Oly has it's quirks, but I've put thousands of rounds down the pipe and it's still holding together. |

I have both and much prefer the dedicated uppers, and that's what I shoot almost exclusively in terms of AR rimfires. I shot the conversion enough to make sure it functioned with a few of my rifles then packed it away in a pouch with mags and ammo as a "just in case" thing to carry along when travelling with only 5.56mm ARs, etc. |

I have several different uppers that lead themselves to different uses and I have them set up with different sights/optics .
With the drop in conversion I can pick and chose the best setup for whatever type of shooting I want to do that day. On the other hand I have seen guys set up a dedicated upper to fit a particular style or type of shooting and that works also. CDNN has the cmmg stainless conversion for like $150 with one mag- Thats pretty hard to beat |
| I have both and I prefer the dedicated upper. The conversion kit is nice because I can move it between several AR's, but in a 1/7 twist barrel accuracy is pretty poor. The dedicated upper is great. Accurate, reliable, and I can run my .22 suppressor on it. You can't go wrong with either. |

I have both. Just for shooting I prefer the dedicated .22 upper, period. On the other hand, I have several 5.56 AR's and some days I want to practice with them without the expense of centerfire ammo. So, I also have a conversion. If you really can't decide, get the CMMG stainless conversion. Down the road if you decide to go with the dedicated they will sell you the upper, minus the bolt. Then you can have BOTH! and save some money.
You can not go wrong either way. |
