m1a in battery

What ultimately STOPS the foreward movement of the op rod / bolt assembly as it rushes back to battery ?
Is it actually the piston which then gets hammered into the end of the gas plug ? If so, seems like one whole hell a lot of chaos, peening punishment to the business end of the stick.

......and is that why my plug is always loose ?

If you use a GI combo tool, it's hard to put too much torque on that gas plug. Mine started loosening up pretty and I replaced it with a GI one and it hasn't happened since. Look closely; the GI plug has a raised diamond knurl.

Yes that is how it is supposed to work. And no it does not hurt anything.
