多謝你寶貴的意見~thx~
I personally suggest you to change your OEM systema buffer tube, since it is totally out of spec. It is neither (mil-spec) nor (Comm-spec). Aftermarket stock tube (you can ask bro sailun412) he can probably help you out. The OEM buffer tube size is in between this two spec, so CTR-Mil spec will not fit (too small), while CTR Comm-spec will be too big and will wobble a lot. If you don't want to change the buffer tube, I suggest you to buy a Mil-spec and sand down the inner diameter of the stock, so you can have a good fit on your buffer tube. Hope it helps.
