Hey folks, new to the forum. Tried searching the threads for an answer to my question couldn't find what I was looking for so please bear with me. I want to replace my fixed stock on the Oly Arms plinker plus I bought several years back with a magpul CTR. I find out after calling them that my buffer tube is commercial not MilSpec (should've guessed). Can you guys give me an idea of what I need to do to swap this BT with a new MilSpec? Can this be done without adverse effects? This is probably a newbie question but I've exhausted my search potential. Thanks in advance.
