I am considering purchasing this conversion unit for my colt sporter ar-15. The company specifies that the rifle will group the same out to 100 yards. Is this correct considering the velocity difference. Anyone owning one of these units concerning reliabilty, cleaning-excessive barrel fouling from rimfire powder ect. your feedback would be greatly appreciated.Thanks Linetech1

  I have the unit and it works fine, played with it at 25 yards and the
  group was a bit low and to the left of the zero I had with .223s but
  the group was good. Be sure to shoot a few reg. .223 rounds after
  the .22s to blow out the gas tube.

  I have the Ceiner .22 conversion for my AR-15 Sporter, and it does function very well. Have tried many varieties of .22 ammo and all seem to function flawlessly. Just for my own reasons, valid or not, I prefer to use "copper jacketed" .22's as they seem to foul less than lead. Cleaning has not been a problem, we all clean after we shoot..... Also have the Ceiner for my Colt .45. It, too, functions extremely well. [8D]

  Mine works great, but it didn't hit the same zero as the .223. Ammo is so low priced in .223 anymore, that I don't even bother with the conversion.
  
  Thanks, Grizztribefans@sssnet.com

  I have one with the 30 round magazine[:D][:D][:D]
  
  It works great in my Bushmaster. Never jams. Point of aim is not the same out to 100 yards.

  I've been using the Ciener AR-15 and M16 conversions for many years. The very first conversion I saw was back in the 1970's from the old MAC company and designed by Max Atchisson. Back then they were marketed by Charles Robinson in Georgia. These early units were not model specific and the same kit was used in either the AR-15 or the M16. The magazines back in those days looked very much like a standard 20 round AR magazine except the had an insert inside for the rimfire rounds and a capacity of 16. List price back then was $79.95- not all that cheap since a Colt AR-15 retailed for $234.95 at that time. You had to shoot it A LOT to get back that $79.95.
  
  MAC passed into history and Mr. Ciener obtained the rights to manufacture this conversion unit. He made a number of changes which improved the units reliablity. The biggest improvement for those of us who had machineguns was the speical M16 conversion with the "anti-bounce" feature that really improved the performance of the rifle on full automatic. Ciener also introduced a 30 round magazine which made the fun last even longer between reloads. The AR-15 conversion continued as before and its reliablity was never an issue with semi auto fire.
  
  There were only two other conversions available that I have ever seen: one was a factory Colt unit which was nearly identical to the Ciener except it would work in the M16 as well as the AR-15 but came
  with only a 10 round magazine and no high capacity mags were ever made available from Colt. Ciener used to make 30 round magazines for these Colt units but the 1994 Crime Bill ended that and he has been out of stock on the Colt magazines for years. The other conversion unit was an over complicated device developed by the US Air Force. This thing actually used a gas action assist and was more trouble that it was worth. The 10 round magazine for the USAF version were simply inserted into a standared 20 round magazine and fired as mormal. Sarco had some of these USAF kits as surplus several years
  ago but I'm sure they are long gone by now.
  
  You can forget about getting the same point of impact with the conversion. You'll have to adjust your sights. Reliablity is not an issue with the Ciener units as they function perfectly with nearly every type of .22 ammo I've tried- including Russian steel cased "Junior" sub sonic ammo. Cleaning should be done on a regular basis as .22 ammo is pretty dirty and you'll be shooting plenty of it. I've yet to have any trouble with the lead shaving that I've heard mentioned by many people. I own two Ciener kits; one AR-15 and one M16 and as a rule I use a dedicated upper for the AR-15 so I'm not too concerned with what goes on with the gas tube since this upper will never be used to fire .223 ammunition. Buy the kit and I know you'll be pleased since it is easy to instal and nothing but fun.
