AR-15 SIG SB-15 Pistol Buffer Tube

I have built close to a dozen .308 AR pistols, and every one of them uses this buffer tube, It is engineered for strength and has a longer length for better spring/buffer travel. Topped off with a SIG SBX brace, it has the look and function of a real "Beast".

nicely made and though it would be ideal for my build but it didn't turn out that way. I had bought a sb tactical brace and the fit was real sloppy. Length was about perfect but I had to permantly glue he brace on to keep it in place with gorilla glue. Come to find out in Michigan anyway the brace has to be removeable. Well I removed it allright. it took a heat gun and lots of soaking with fingernail polish remover to get it off. NO WAY I could have done it at the range. thing is in Michigan overall length can only be 26 inch and I was an inch long with the small spacer and a 1/2 inch to long wthout the spacer. Wouldn't be a big deal if I could easily remove the brace and technically not illegal but I don't want to be hassled over it either. I swapped it out for a standard tube and still used the sb tactical brace and I was a much better fit. I should have read more carefully that this is a dedicated tube for a sig brace. I'm doing another one in 9mm right now and I just went with the shockwave blade and dimpled tube. Probably the best solution out there for cost vs functionality. Keep in mind too that this was with an 8.5 barrel. A 7.5 inch build would be perfect. Ill save the tube as I want to do a 300 blackout too and will do that at 7.5.

Does what it says it does. I built a 458 socom and it kicks like a mule. My face was so close to the receiver that it woukd kick back and touch the tip of my nose. With the receiver extension it added the perfect distance to prevent that from happening.

I looked high and low on the web for this tube. The website is easy to use, product is made well and the price is great. The product shipped quick and the assembly was easy. I will keep your store in mind and pass your store name to my friends.

There really isn't more to say. This buffer tube and the SIG Brace work seamlessly. I'm using the SBX which isn't as long as the SB15, but it still looks and feels good. Would recommend for any pistol build.

Fit to both lower and brace was perfect, easy assembly as well. Excellent product from an excellent company. Thanks.

I was so pleased with the last two buffer tubes, that I ordered two more...GREAT products at EXCELLENT price points...Service is outstanding too!

KAK had everything that was looking for to complete my two .308 pistol builds. I ordered the SB-15 buffer tube to go with the SBX SIG brace, and was very pleased with both products. Everything finished out so well, that I have started two more builds and plan to order both again.

just remember to purchase the ring without the notch or just grind ur old 1 with a dremel...
