dalbert Posted April 7, 2020 Report Share Posted April 7, 2020 I've heard that the CMMG uppers are good, but I don't have any personal experience with them. I bought a Ciener conversion kit 30 years ago, and never have sprung for a dedicated upper. I'd be interested to know what you end up buying, and how you like it. Maybe there's a dedicated .22 upper in the future with my name on it... David Albertdalbert@sturmgewehr.com Link to comment Share on other sites More sharing options...
emmagee1917 Posted April 8, 2020 Report Share Posted April 8, 2020 I either bought a CMMG upper or I bought a CMMG bolt assembly with a 4 and something length barrel and put it in an upper with a handguard that goes over most of the Sparrow suppressor that's attached to it mounted to an SBR carbine lower with a Hellfire binary trigger and a magazine adaptor to use S&W AR15-22 magazines allowing the rifle's bolt hold open to function . Also bought the charging handle with the extended arm to clear the scope IIRC .Chris Link to comment Share on other sites More sharing options...
mgvince Posted April 8, 2020 Report Share Posted April 8, 2020 As said a CMMG dedicated upper is your best bet. You can buy one or build it yourself. However it can be very hit and miss getting an M16 to run well with .22lr. You have to get a trip and antibounce weight kit. CMMG kit works well. I use Black Dog 26 round stick mags and 50 round drums. I built a 4.2 inch upper and it runs very well. I run a Geissele SSF trigger with the springs that come with it in a Colt 9 million series M16. I have been lucky that I didn’t have to tinker with it to get it running. I do use a pressure plug also. Link to comment Share on other sites More sharing options...
Frank Iannamico Posted April 8, 2020 Report Share Posted April 8, 2020 Hands down the CMMG!! i have one for my M16 works great, right out of the box... A dedicated upper is suggested, shooting a lot of .22 through a 5.56mm upper will eventually plug the gas tube with lead.Suppressed full auto .22 is FUN. A GREAT mag loader is the McFadden Lightn' Loader. Loads 30 round mags in seconds. Adapters are available for many other .22 mags, loader is only $23.50 adapters are only $6.50. Best money you will ever spend for a loader. https://www.mcfaden.com/McFadden-Machine-Lightnin-Grip-Loader-s/1828.htm Link to comment Share on other sites More sharing options...
Bridgeport28A1 Posted April 8, 2020 Report Share Posted April 8, 2020 Frank, is there an adapter that works with the Blackdog Thompson magazine used with the Merle kit? Link to comment Share on other sites More sharing options...
Frank Iannamico Posted April 9, 2020 Report Share Posted April 9, 2020 Frank, is there an adapter that works with the Blackdog Thompson magazine used with the Merle kit?Not sure check their website, or email them. If they don't make one ask them if they will. I got them to make an adapter for the .22 caliber Glock conversion. Link to comment Share on other sites More sharing options...
junglewalk Posted April 9, 2020 Author Report Share Posted April 9, 2020 Thank you Gentlemen, I appreciate your advise:> It will have to be a designated 22 cal full upper...…. Link to comment Share on other sites More sharing options...
Grasshopper Posted April 10, 2020 Report Share Posted April 10, 2020 (edited) Hi, There is a site called "Right to Bear" here in Florida. Great guys. In the past have shipped really fast. They have the CMMG parts as well as a generic that works great also (and saves a bunch). They also have all kinds of uppers w/o forward assist or gas port stuff that you don't really need for the 22 conversion. Here is my dedicated 4.5" 22 upper, Sparrow, and low red dot on an old SP1 RR conversion running a JAC conversion and a CMMG collar. All normal 22 HV ammo is subsonic with the 4.5" barrel. No fancy ammo needed to be quiet. Works great. Runs fast. Wish it ran at 750 but it is closer to 950. Watch your sear timing. I set mine really retarded and use the ball detent mod to remove the bolt bounce. I can get down on the red dot just fine. YMMV Grasshopper ps. In the olden days, Rick Kuehl had really great dedicated uppers. His last builds were the best but hard to come by.

mattnh Posted April 13, 2020 Report Share Posted April 13, 2020 +1 on the CMMG upper You will also need their FA trip & anti-bounce bolt kit https://www.opticsplanet.com/cmmg-inc-auto-sear-trip-and-anti-bounce-weight-kit-22-arc.html Link to comment Share on other sites More sharing options...
Colt Chopper Posted April 13, 2020 Report Share Posted April 13, 2020 I would pass on the Chiappa, better stuff available. CMMG IMO Link to comment Share on other sites More sharing options...
hushdistribution Posted July 9, 2020 Report Share Posted July 9, 2020 CMMG is the way to go. They sell them in two options as a conversion bolt to your standard 556 M16 or a stand alone .22lr upper. Definitely go with the stand alone unit. Youll also need the full auto dear trip kit and anti-bolt bounce weight that are sold separately. Link to comment Share on other sites More sharing options...
