have the Spike's tube which is a little larger than a standard carbine tube. Still theca cheek weld was way too big.
someone posted this (below) in another archived thread, but it appears to only be for that smaller CAA cheek riser, does anyone know the best way to mount these things? I used a cut up bike tire, but it's so jerry-rigged I can't stand it on an otherwise, kick-ass build 
talked to the company that makes this. they said they are making one specific for the bigger CAA cheek weld. Should be out in the next few weeks |

It's the outside diameter of the two different types for carbines that is different. Every standard lower has exactly the same threads, and all receiver extensions have the same threads.

I am unfamiliar with the PSA pistol tube, but it is threaded in slightly too deeply if it is interfering with the upper. If it has a castle nut, it is an easy fix, back the tube off a bit (if it is indexed for the buffer retaining pin like my Phase 5 is, try one turn) and re torque the castle nut. Problem solved. |

Not sure about using parts off ebay for my firearm, but that's just me...But I do know someone using a kit off Amazon for his pistol and he hasn't had any issues. I picked up my phase5 kit for about 68 shipped when they had 10% off for the 4th of July. |

I did a pistol build about 3 months ago and got a tube like this from High Powered Armory when they listed them on sale on their facebook page for $75.00. It was complete with castle nut, back plate, spring and buffer thought that was a good deal.
Not sure if they still offer them at that price or even offer them at all but it functioned perfect. Never had any of the problems I had with some some of the shorties. |

it'll fit on any round pistol tube. has to be round. can't have the little flat area with the notches for an adjustable stock. the phase 5 fits tightly in the sig brace. I'm waiting on an RRA one to arrive to see if it'll work with with and my lower since the phase 5 refuses to thread into my lower. 
|
| I just put together a kit with the RRA pistol buffer tube, and the Sig brace/stock thing does fit pretty tightly. But, no castle nut on the RRA tube makes me sad. Anybody have a good way to get that thing on super tight? FWIW, this is an LMT lower, with a 12.5 BCM upper, functions great so far with an H2 buffer. |

FYI, Thordsen just released an adapter for the CAA cheek weld
Here I think you have to use it with their cover, but it's not a bad deal. just got it in and put it on. Perfectly snug fit and well made. I am honestly very impressed. Magpul quality for polymer and fit and finish |

Yes, Thorsden will confirm and has letters posted on their website for each of these parts. In fact, they won't work with a pistol tube as it uses the 6 slot section to index and keep the cheek weld in place. |

Also, I am not sure I want to buy it right away...anybody got a good way of rendering the receiver extension unable to accept a stock until I buy the CAA/Thordsen? |

Essentially it's a custom pistol tube they make. It has no holes or slots and no way of putting on an adjustable stock. I'm not 100% on the legalities of using a regular buffer tube. Some say it's ok and others say not to. The law is very vague and would hate to be the test case. |

I assume that is to be used for those looking to test the waters |

I've been using the Thordsen AR PISTOL BUILDERS PACKAGE for my build and it works perfectly. The CAA adapter kit that's included makes everything fit together without any wobble at all. Both pictures from the Thordsen site.  |

| Good morning, I have already searched for this company on here and have come up dry. Have any of you heard of Guntec usa? I found a package deal for their heavy pistol buffer tube with foregrip along with a ergo grip shipped for $125. I am rigging up a 10.5" pistol with a CMC triggers 3.5 flat in it. Any feedback appreciated. |

I'm planning on running an SB-15 on a KAK tube. Took a good long look at KAK's many offerings and now I'm somewhat confused on which one to get. Do they all use carbine springs and buffers? Any reason one should want the castle nut style, to me the straight screw in tube looks cleaner? Looks like most or all of them can be had with an end plate with a Q/D swivel receptacle. Think KAK ought to make a comparison chart so it's easier to see what features you're getting.

Think KAK ought to make a comparison chart so it's easier to see what features you're getting. All use carbine size/style buffer systems. The KAK super tube has a castle nut for staking your buffer tube. I would recommend looking up the advantages of staking a castle nut on a buffer tube. I went with the KAK super tube with the castle nut as some have had issues with their buffer tubes coming loose/unscrewing a little bit under heavy round counts. |

I am also in process of building my AR15 pistol and plan on using an SB15. I really like phase 5 parts and was planning to use their buffer tube assembly. If you look at the specs for the buffer tube, it states that it has a diameter of 1.25". The SB15 website states that the brace fits buffer tubes with diameters between 1" and 1.2".
My question is has anyone had any issues with mating the SB15 to the phase 5 buffer tube? Does it require removal of the buffer foam pad? Want to make sure before I buy and would appreciate any feedback. BR, Nik H |

I use the KAK Super Tube, however I have heard the Phase 5 gives a very tight fit and does not let the SB15 move around very much at all once put in place. Because of said diameter differences it is a little difficult to get the SB15 on but once on it is snug and secure. Also when putting on the SB15 on to the Phase 5 buffer, remember to take off the foam cover. I believe with the Phase 5 receiver tube you can actually make the SB15 sit flush against the rear of the lower receiver, but this I am not sure of. From another, Nik H

Think KAK ought to make a comparison chart so it's easier to see what features you're getting. I have one of each on a couple of my builds.. the castle nut version allows you to use any standard endplate and install the buffer tube as you would a standard carbine tube. All of their buffer tubes use standard carbine springs and buffers. There is a spacer in the rear of the buffer tube to make up the length difference with the extended tube. You can use the solid version, the only caveat of that is that you need to either use a pistol tube endplate or take your desired endplate and just grind the nub off with a dremel or file that would engage the bottom slot in the buffer tube. You need to be able to hold the endplate in place and screw in the buffer tube, which you can't really do with a standard endplate that engages the slot (thus the castle nut to allow you to rotate the buffer tube into position with the endplate engaged and then tighten in place with the castle nut.) There are benefits to using a staked castle nut and many choose the castle nut versions for this reason.. ;) Not a very good phone pic, but... lol
