| A buddy is having me coach him through very first build... In his horse trading for parts he picked up a used ACS stock unknown if is milspec or comercial. He is nearly done with the parts for the build with the only thing left is the receiver extension. Since it must match the stock Is there any way to tell the difference in model or tube diameter between the two stock formats? I Have a caliper so i can measure if needed. |
