This has probably been asked to death and if so I apologize now. I'm running the Ciener .22 conversion kit in my 20" A2 with 1in9 twist. I like to plink at my parents place with my kids and dad when we are there, but like to keep the noise really low. I can shoot the Remington SubSonic through a bolt action rifle fine but find they don't cycle the AR. With a mix bag of .22 Non-subsonics, it runs like a champ with no FTF. Can someone point we in the right direction. Suggest a better ammo which will cycle my rifle and still be subsonic. Is there something I should change to the base Ciener kit? I don't have the money right now to try and get a supressor, so any other ideas would be greatly appreciated. |

That is a problem you will have with most, if not all, subsonics. I've never seen them cycle an AR. Try the CI Standard Velocity target rounds. They actually stay subsonic out of most weapons and are only like 20fps different than the CCI Subsonic rounds. I bet you get the same result though. Mark |

You need to reduce the spring force that the under powered subsonic ammo must overcome in the blowback system. Spring pressure comes from the Ciener's recoil spring and from the lower's hammer spring. The best solution is to reduce the hammer spring strength; reduce the kit's recoil spring strength very much and it won't be able to fully chamber rounds when things get dirty. A $4 reduced power FCG spring set made my kit perfectly reliable with subsonic ammo. The lighter hammer spring still ignites all .223 ammo just fine. An even cheaper mod is to cut one leg off of a spare hammer spring. As a free experiment, try reinstalling your existing hammer spring with one leg above the trigger pin and one leg below it. |
| Thanks for all the help folks. I desided to try and modify the hammer spring (figured if I broke it, it's a couple bucks to fix). I filled the mag up and was able to shoot with no FTF. Put about 100 round through before it would give me some problems. Never failed when I shot it, but when others did. Took it apart and gave it a good cleaning and used remi oil instead of grease to lubricate it and put another 100 round through it with no problems. Had a blast (no pun inteneted). Thanks everyonoe. |
