    if its not a gas piston then what is the round object located inside the gas collector which connects it the action rod? no matter what its called, it falls out sometimes and stops the rifle from operating.

    Thanks for the info. BAMBIHUNTER. Even though this was a good site, it didn't tell me why the gas piston falls out sometimes, or what should keep it locked into either the slide or the gas block.
    Maybe "vicg1" should try going to this web site for a little mini-14 education.
    Thanks again for the help.

    Well, the part is indeed called a "piston", but it is also called a ""gas pipe". Anyway, it is held into the gas block by the gas port bushing which is a very short tube that goes into a hole on the top of the forward end of the piston and into a hole on the bottom of the barrel. So, if yours in missing, or is a little short, the piston will float back into the operating rod. First check and make sure that you have this part. It is really very small and easily lost. Next (if you've got it) try tightening the gas block screws down tightly, and check to see if there is anything that prevents the halves of the block from coming closely together like a build-up of carbon, etc. If it still doesn't work right you will need to replace the bushing, piston, or both. If you have a 180-series (the original model) you will have difficulty in obtaining the parts. I haven't worked on one of these gas systems for awhile, but I believe that the 180 and 181-up series bushings are different.

    Sorry if i came off the wrong way earlier. This last piece of info. was very helpful. I went back to the exploded view, and i see what you are talking about.Its called the "gas pipe bushing". I had in mind something like that.


    If there's one thing i've learned about buying, selling, or repairing firearms is, you've got to have a sense of humor.

    On a mini -14 the gas piston in a little lipple looking thing which is held in place by the regulator .The regulator is inside the gas block and can only be seen if the top of the gas block is removed .The regulator also aligns the gas hole in the barrel and the gas block.If there is no regulator then I would not shoot the gun.To see if the regulator is there remove the four allen head screws at the end of the stock .That will allow you remove the top half of the gas block then remove the bottom half from the barrel that will allow you to see if there is a regualtor.Are you sure you are talking about the gas piston that fits in the gas block and the bottom hole of the oporating rod/charging handel? There is a small bushing at the bottom front of the receiver about the size of a nickle .It is held in place by a pin and is used by the spring guide rod.The pin will fall out easly when the stock os removed.I ask this because it is very strange and extermaly dangerous for the piston to be able to come out without the gas regulator being removed.
    To reassamble the gas block .
    1. place the piston in the lower half of the gas block and align the holes.
    2. insert the gas regulator in the hole on the lower half of the gas block.
    3.then align the gas hole in the barrel and the lower half of the gas block so the gas regulator in the lower half of the gas block and the hole in the barrel fit .You should feel the regulator fall into place in the gas hole in the barrel.
    4.place the top half of the gas block in place and insert the screws but only tighten them one or two turns so they remain loose .
    5.put the stock back on the gun make sure everything stays aligned then tighten then snugly. A small amount of removeable lock tight should be used on the four screws to keep them from comming loose .
