I just got the commercial ACS stock and a commercial buffer, installed them both and the stock is very tight around the buffer tube. It is extremely hard to collapse and extend it, i have to use both hands to pull on the stock to extend it and can barely move it. what should i do? here are some pics of scratches the stock has made on the tube:
this is the bottom of the stock, and you can kinda see how the sides are tight on the buffer tube: |

I'm positive the stock is commercial, and the tube is supposed to be, the stock and tube were bought together in a kit. It would have to be if it's too big, because mil spec tubes are smaller in diameter.
No I do not have another tube or have a friend that has an extra. Should I just buy another tube I guess? |
| It fits around the tube, it's catching on that extended part on the bottom on the tube, where the "holes" are that pins in collaspable stocks attach to when you collapse them. Kinda hard to explain, but do yall understand where I am talking about? It's where the scratch marks are in the pictures. |

Commercial-spec carbine receiver extensions have a larger radius in that corner. Please see Carbine Receiver Extension Comparison for reference. By the looks of the pic, you may have a mil-spec stock squeezed on a commercial-spec tube. To positively determine which size ACS you have you can pull your butt-pad and look down the core on the left side behind the battery plug's tether. There you'll see a little "C" or "M". Some measurements of your tube itself may also reveal something. |

Military spec stock sold as a commercial, even says commercial on the magpul box it came in, but the stock is mil spec. ETA: called magpul, told them what happened, and they are going to send me a commercial stock and a box with prepaid shipping to send the old one back to them. i'm pleased with their customer service. |
