Cleaning (properly) Ruger Mini-14
What can some of you tell me about going beyond the Ruger instructions for cleaning the Mini-14?
I'm especially interested in proper cleaning of the gas port area. Ruger instructions warn not to disassemble this unit because it requires special tools. I'm wondering how much build-up of crud is inside this 'gas block assembly'? I had this gun jam a few times and thought it was due to cheap, 5.56 ammo so bought some Remington .223 ammo and had one jam with it a couple of days ago. Empty was lodged between bolt and receiver with mouth of case to the front. Another question would be: What's the most common cause of jams with this gun? I would guess, faulty magazine. I have a 20 round Ruger magazine. 270 |

The gas block never needs disassembly or cleaning inside.
Re the misfeeds...very rare with factory mags. Try another... |

How new is the rifle and how often does this occur.
Mini14's seldom require removal of the stock.

Magazine would be my first suspect.

If fired rounds are hanging up sounds like a dirty ejector,perhaps you were using coated steel cased ammo before,I believe a good cleaning will solve the problem. I've owned 3 and never had one fail.

Thanks for your responses.
The gun was made in 1996. This last jam--empty lodged between bolt and receiver and facing forward--using Remington .223 ammo. Not 5.56. Gun was not very dirty at all except for usual burnt powder residue in gas piston area. Have it cleaned and back together. This gun has some kind of adjustment screw at front of gas piston area. It's out in the open requiring no disassembly to adjust it. What's the reason for this screw? I would guess to increase or decrease the amount of gas that works the action. Maybe this needs adjusting. How do you adjust this properly? This is located right above hole for sling swivel. 270 Last edited by 270; October 20, 2011 at 12:53 PM. |

Sounds like an adjustable gas system ...heard of them on a mini but have never seen one.
Give it a try it may be short stroking or something.

It must have an Accuracy Systems adjustable gas block:
http://www.mini14gasblock.com/ If that's the case, then crank open the gas block a bit to improve cycling. You're correct, you can adjust the pressure to the gas block depending on the ammo you're using. A great addition to the Mini-14. |

tobnpr,
You hit the nail on the head. Even instructions at their website on how to adjust the thing. You can adjust it from--won't cycle to throwing brass 25-30 feet--which it NOW does! I see on mine the screw is backed-out a lot and I'll bet as I tighten it down the brass will land closer to me. The setting I'm really after is the one that will make my Mini-14 as reliable as possible. May give them a call. Thank you. 270 |

The best thing to do for reliability is get a bunch of Wolf ammo. Wolf is the most underpowered stuff you can buy that I know of. Adjust the block so that the Wolf reliably cycles and kicks the brass at least 10'. Once you have this setting your Mini will then reliably cycle any 5.56 ammo you shoot in it.
