AR-15 SIG SB-15 Pistol Buffer Tube

I have built a couple of AR based pistols, one in 556 and one in 300AAC. Both have been using a conventional pistol buffer tube, but.. the oal of the builds with the 10.5" bbl was just short of 26" and I wanted to get the oal to at least 26". Enter the KAK SB-15 buffer tube, which adds an extra inch or so of length to the oal of the weapon (now becoming more critical in some states). I added a Sig Brace from KAK as well and now have a very functional 300AAC weapon, much more user friendly than the previous configurations I had put together. I want to add, as many have already, that the customer service is outstanding. I placed my order on a Saturday, got shipment tracking via USPS Priority mail on Sunday and had the parts in hand a few days later. I will now have to order up another set, as my 556 pistol is very jealous of it's brother...

I absolutely love it. Seriously, the quality, fit, and finish is excellent. I ordered the extension rings with this, also. They flawlessly match the tube with my SB15. This setup has become my favorite gun to shoot, hands down. (I did NOT see that coming!) My AR pistol went from being a loud "toy" to a highly functional weapon. I shot a 1.5" group out of my 10.5" barreled 5.56 @ 100 yards off a table. Couldn't believe it.

I have been building AR's for quite some time now, and had become somewhat bored with the standard parts I'm asked to use, on their builds. Then I decided to build a couple of 300 Blackout pistols, and see if I could invent a better mouse trap, so to speak. Quieter running suppressed with supreme accuracy & as short as I could make 1, and the other one with a Red Dot & 3x magnifier for accuracy & a tactical weapon at 200+ yards. That's when I decided to find something that would work better than a standard pistol buffer tube, due to their limited Functionality!! I just happened (to get Lucky enough) to find out about this New Product that KAK had started making here in the United States? So I ordered one so I could eventually Buy & use a New Sig Brace whenever I could find 1 of those in stock, just to give it a try. I ordered the Sig SB-15 Pistol Buffer Tube from KAK along with a few other items around 4 P.M. That afternoon. I was Shocked later that night when I checked my email to find several emails from KAK Industries? They sent an Order Confirmation Email to me 10 minutes after I had placed the order. Then a 2nd Email 30 minutes later to let me know my order had already been packed up and Shipped out with the USPS with a Tracking Number too! I haven't seen Customer Service like that in Years, and I am still shocked at how quickly my order was processed? Needless to say, my package was delivered to my Home just 2 Days later, and I am still Shocked at how Quickly the process went? They've either got the Keebler Elves working in the shipping department, or this is a company that puts the Customer Satisfaction first. And as a Customer, I like that. The Sig SB-15 Buffer Tube installed in my 300 Blackout Pistol, made such an Incredible difference in the way that it can Now be Fired, I just can't say enough good things about it... The diameter of the KAK Pistol Tube is just a hair different than the standard tubes, but it makes all the difference in the World! As well as the shoulder on Front of the Tube that gives you a good positive stop position for the Sig Brace.

I am using this tube without the sig brace currently and it is a great product. Well made and shipped fast. The extra length is great for stabilizing your ar pistol with or without the Sig brace. Just what I was looking for.

Excellent choice. Was Leary of it at first, then it showed up and BAM! Perfect fit and look! I will be doing business with KAK again.

Same day shipping and excellent quailty. Will def being doing business again! If you plan on building an AR-15 pistol build with a SIG SB-15 this tube is for you.

The KAK SB15 pistol buffer tube is good quality, looks sharp and is a great design for use. I'm also very pleased to say their customer service was all around excellent! There was a mix-up on my initial order. Not a problem, KAK was fast to get my order squared away with an additional bonus (thanks). If you plan on building an AR15 pistol with the SB15 brace, let me suggest this IS the buffer tube for you.

I bought this based on forum reviews and what I saw on YouTube. Very happy I opted for a KAK tube as the quality is excellent, contact with KAK Industry was excellent as well, and it was shipped fast.

perfect finish and tight fit with the sig brace. worth the money
