SIG TUBE LENGTH ADJUSTMENT KIT (KAK SIG LAK)

These spacers are perfect for the KAK pistol buffer and SB-15 brace. With the tube, spacers and brace installed, the length of pull matches my Ruger 10/22 Takedown, which is perfection. It's great to have the option to shorten this at will.

I bought this for my sb 47,though it says it will only fit the sb15. It did take some work, I had to grind or some material from the inside, but not much. Fits great and does the job well!

Similar to Lawrence' s review ( and my motivation to write a review, because his review is the reason I order the adjustment kit) I'm 6'3" and the longer of the two extensions is just what I needed to get a better fit with my sig brace. I initially put both extensions on my buffer tube and felt like I was cheating so I went with the longer extension. It puts my AR "pistol uppers" right were I need'em. It even make handling my 7.5" upper fun ( I was going to offload it but now it's a keeper) The extension pieces have excellent finish on them. I'm about to order another tube and extension kit for my brother's 10.5" build. Only thing they need to make now is an end cap for the sig brace. : )

These spacer rings are great quality and the best way to make the SIG Arm Brace a custom fit. After receiving them, I decided to go with a Kak buffer tube because the Kak systems all fit and work so well together. These guys are terrific and I had a number of questions because I wanted to make this set-up perfect. All my questions were enthusiastically answered and lightning quick. The bottom line is that I now have a firearm set-up that feels like it was made just for me... because it was. For just a very few dollars, an interesting firearm was turned into one that a shooter could love. I will most definitely be a repeat customer and... thanks for the help.

A bit pricey, and I only needed the larger piece. That did fit well though and made the length perfect.

Works perfect wit the KAK Sig Tube.

Item is made to exact specs, works great in placid brace perfectly where needed. Highly recommended is you are planning an AR pistol, in order to get it to fit correctly on your arm.

I have short arms (5'6" myself), but I like the brace far back to wrap around my arm at its base, these rings do the trick. Pistol and arm are like one, makes you feel like MegaMan. If you need more length of pull on your brace (whether you use the brace correctly, or otherwise) these do the trick, won't break the bak, and look great.

First I had the Sig Brace, I liked it over just the plain pistol buffer. However it twisted and turned. So I upgraded to the KAK Sig brace tube. This was a huge improvement however it still left something to be desired. If I use the brace as it is intended I was wearing it more as a bracelet than a forearm brace. Shouldering it I was hunched up so bad I had fatigue in my back after a very short time. I saw the spacers and for the price and KAK quality I ordered them. I have both spacers on and it has made all the difference. Using the brace as a brace it sits midway up my forearm, shouldering it feels about the same as the third position on and adjustable stock.
