I’m ordering the blue immediately.
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.
Great stuff!
with the green one, you can tighten the vise on four positions, which helps to stake the castle nut from multiple angles
Quarters never fail!
That coin shimming tip is great! I'm still using the reaction block and mag well block with two parallel vises. I think I got that tip from here as well.
You'd think for $200 Geissele would include some form of adapter that extends to the grip on the lower
I have the NC star jig. How would you recommend staking the castle nut with that one? Could I just remove it from the jig and somehow secure the lower receiver in my vice?
Do you know why the green jig no longer has screws on the sides like the one in your video does?
Anything like this for AR-10?
New to building AR platforms and really enjoying your videos. I just bought the Botach and will use your coin tip on my next build.
Time to 3D print that $300 jig….
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.
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.
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.
There you go, nickel and dime me again.
I work at a Gun Range and our Gunsmiths are telling me about your channel. You do a great job and between you and work, I'm learning a great deal. Thank you!
Awesome tip. Gives new meaning to "nickle and dime " something.🤣
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.
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.
Thank you again sir.
*calibrated coin shims!
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!
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.
great tips
Talk about "Nickel and Dime" something.
Awesome information. Thanks for sharing. I do appreciate it.
Chad, can a bent retaining cotter pin for the firing pin cause light strikes?
Maybe if you have a machinest buddy, they could remove some material from the jigs to ditch the coins.
Great video!
Go to your friendly machinist and have the two cut down .
🙂
Hey Chad! For your info, the Green Monster has 4 Lobes at 12 O'Clock, 3, 6, and 9 so you can grab it in the vise at 90 degree intervals for easy access to stake the castle nut.
