  1. Awesome video, my friend.. Got yourself another sub AND now I get to tear down my lower that I finished this morning. Knew I had forgotten something. One little f'n spring and I could figure it out..

    This noob builder thanks you mucho..

  2. This is one of the most useful guides on YT for a first time assembler. The black parts, black mat, black t-shirt and dark background conceal a lot of the detail. Increased contrast would make this infinitely better. Nonetheless, a great summary of parts, where they go, how to not send them into your eyeball and what they do.

  3. Very informative and I like how you describe each piece that you're putting in, however I would have liked you to zoom in as you're putting various pins in so that I can see up close as you slide a particular part in, the back camera angle doesn't help me much cuz I'm very visual… But otherwise great video

  4. I appreciate your video for my first build. But I do want to say, and sorry to be that guy, but I found an easy way to install that front pivot pin without losing it. Just sit the stripped lower upright, install spring, carefully set divot on top of spring, apply pressure slowly with pin. Push through and done.

  5. Does anyone know where to find a good close up video of the catch pin release having a horrible time with mine the spring does not fit the hole what so ever.

  6. I thought I would purchase a few of the tools used by this idiot to help me on my next builds. After waiting for almost 4 weeks with no notification except the money being withdrawn from my account, I contacted the guy by email and found that he was a rude little shit that told me that if I didn't like the wait, that I didn't have to do business with him. He and I exchanged some pleasantries through several emails which he treated like he was a triumphant shithead because he didn't back down to a customer that was originally inquiring about my order. His customer service skills absolutlely suck and I would not recommend purchasing anything from this dipshit unless it is your last choice and even then I would advise against it.

  7. When you put the trigger together, you used a detent to keep it all together then placed it into the lower. After you inserted the trigger pin, there was no mention that I’m aware of, what happened to the detent. I’m assuming the trigger pin pushes out the detent and holds everything together.
    Thanks
