  1. Thanks for this video. After over rotating a negative to spec buffer tube I started researching buffer tube alignment. Went back to my previous 6 builds and noticed a slight cant on a few of them.

    I bought the VISM jig but it was out of spec (imagine that). It’s on a warranty return but NCStar is out-of-stock. So I bit the bullet and bought the Geissele block (on sale though).

    Not only do I now have perfect alignment on my buffer tubes, but it also made staking the castle nuts so much easier. I just wish there was a jig for the UBR stock.

  2. I was struggling with a wandering lower-to-buffer clocking issue during a build just this weekend. It turns out I have everything I'd have needed to fix it, without realizing it. Please award yourself one gold star and a banana sticker.

  3. Just finishing up my first build and finding your channel has helped me out a lot and has gotten my OCD and tool addiction in overdrive. I ordered the blue Vism jig and the FCD castle nut wrench and already thinking what's next. Thanks for the detailed content you put out, I've been benge watching your vids and now feel like I made good decisions on my build parts.

  4. I always purposely canted my buffer tube the opposite direction that you would tighten the castle nut. That way when I do the final tightening, the buffer tube gets pretty close to straight. Of course results differ depending on the fitment of the back plate into the lower. I recently did buy the Vism jig for under $30 on sale. Haven’t used it yet though.

  5. I don't really build enough to invest the money in these, I just eyeball it and mine look good and straight. If I did one that looked off, I would loosen it and try again. I didn't even know about these until now. Maybe I'll get the NC Star some day.

  6. When you mentioned you like to make it as perfect as possible I couldn't help contain myself laughing. You are the epitome of perfection and I've been soaking up your intel every chance I get. I have nothing but respect for you and truly appreciate your sharing all this intel. Thank you so much Sir.

  7. Chad, Bought 3 of the Green “Incredible Hulks” months ago, can’t be more pleased! Gordon makes a awesome product, the Geissele and NC-Star I have as well but By Far The Hulk is My personal Fav! Thanks for the Vids!

  8. lol, I've run into the mis clocked buffer tube issues before. Ironically the one that I have that has this was a BCM lower. Perfect in every way but slightly clocked to where it's noticeable if you flip it on it's end and look down at it. not going to do anything bad as you said, but just enough to irk me that it's a freaking BCM lower that did this, not a PSA.
