  1. I bought a stripped Mega lower receiver (Ambi). It came with the roll pin for the bolt release installed and came with a detent and a large screw in a separate bag. Do you have any idea what thats for?

  2. im a noob when it comes to buffers, and buffer tubes, and stuff…. so would this carbine buffer: bravocompanyusa(dot)com/Carbine-Buffer-p/buffer%20carbine.htm work with a 16'' ar-15 with a milspec stock?

    not trying to spam just asking

  3. I find it very good to build a rifle at least once. You really get to know your rifle much better that way. ARs are a bit tricky though. Of those that I have built, I find the gas system to always be a pain. It is very touchy about getting everthing just right or it will flat out refuse to work.

    Yea, I have seen a lot of innocent mistakes made by non-professionals who assemble firearms.

    And since there could be the potential for the firearm (and someones freedom) to be focused on in court, we suggest a professional armorer be consulted about any assembly, modification and / or repairs
