Hi everyone,
Here's what I have so far: Anderson Upper Piston Kit Lower Kit My end result is to have a Piston Pistol, but I am looking for a retractable stock..... I can't even seem to find any buffer plugs let alone the type of stock I am looking for. I want something just like this Retractable Buttstock. Does anyone know where I can find something like that but cheaper, or even the plug? |

Not from what I've seen, I thought it was DI's that needed buffer assemblies. If it has a retractable stock it can still be classified as a pistol like the ak-74u. Pistols can't have stocks. It would be an SBR if you use it with an upper with a barrel < 16" and would require the tax stamp. This Is An SBR, Not A Pistol |

Maybe I'm wrong, but doesn't the AA piston kit you linked require a buffer assembly to function properly? Also, adding a stock makes it an SBR and not a pistol. This and this. Yes, AA needs a buffer - just look at where the bolt carrier is going to go  . Even having a stock without also owning either a compatible rifle or enough parts to construct a complete rifle could be constructive possession of an unregistered SBR.
@OP: In the kindest possible way ... seek professional help or do a LOT more research before purchasing, with all due respect, you're dangerously ill-informed at the moment! Richard |
They're just trying to tell you that if you build a "pistol" with a butt stock of any kind, you will be in violation of the NFA and will get loved tenderly by the BATFE. 
if you're simply looking for a pistol lower parts kit, get something like This . The one you listed is able to have a stock easily attached - not a good idea on a pistol. |

It doesn't matter if the stock is retractable or not. If there is any kind of buttstock on it then you are in violation of the NFA. If you don't believe us then try it out and enjoy your ten years in jail.
FYI putting a retractable stock on an AK74SU makes it an SBR too if you have been looking at krinks with braces on them thats a different thing. p.s. if you are going DI then you will need a buffer tube system. If you want a stock that looks like a nordic but includes the buffer tube and bolt I can recommend the NEA CCS. FYI this is a registered SBR

That depends on the ammo, shooter etc. Barrel length will dictate muzzle velocity not necessarily accuracy. What barrel length are you going for, what optics are you planning to run etc? My barrel options are 11.5", 14.5", and 16". It will fire 5.56. I have an EOTech and an ACOG I can put on it. |

What's their site? Here is one at Brownells: link I would also suggest you head over to the SBR forum and do some reading over there: SBR subforum Good luck with your build. If you are going with a 16" barrel or a 14.5" with a pinned and welded muzzle device then you don't have to worry about your build being an SBR. Only if you pick the shorter barrel option. I would expect decent accuracy out of a 16" barrel out to 500+ yards. Like i said barrel length won't necessarily effect accuracy but if you try the same thing out of the 11.5 there are several other factors (including the aforementioned muzzle velocity drop) that will effect you. If you are going for the 11.5 and are stating it's a CQB build I would expect your optimal range (the range I would most likely train in) to be 0-200yards. p.s. Don't know where you are in NC but i'm one state up so if you need any help let me know. |

Well shit.
I didn't realize there was so much BS to run through. I guess I'll just make this into a carbine and go with the 14.5" or 16". From what I've read in other forums, there isn't much difference between the two besides length. Thanks for the assist, I'm in Raleigh. Will I have to run through a bunch of hoops going through that route too? |

No you will be good man just make sure if you get a 14.5" barrel you get the muzzle device pinned and welded to give you an over all barrel length of 16"+
If at some point you feeling like doing and SBR I can probably walk you through the forms. Other the the $200 tax stamp and the wait the forms really aren't bad. |

Other the the $200 tax stamp and the wait the forms really aren't bad. Why 16"? Will there be an advantage or just negating legal ramifactions? How does one eliminate the buffer assembly anyway? I would have to put the spring in front of the bcg wouldn't I? |
| I was about to build a 13.5 " 300blk but after some research on the rounds ballistics I found that 8.5 to 9" would get the round going fast enough to take advantage of most supersonic factory loads inside of 250 yards and would work great with subsonic loads and a suppressor ( overall length being a huge factor). Longer barrels will work fine and arguably wring more performance out the 300blk round but it seems a waste not to take advanatge of the short-barrel capability the round offers. |

Some piston kits will allow you to eliminate the buffer while others won't you really have to research. Try posting something about it in the piston section i'm sure those guys can help you out. |

I was pleasantly surprised by how accurate my 8.5" 300 BLK was when I took it to the range the 1st time. It was every bit as good as my 16" especially with the 110gr Hornady V-MAX.

Not a 300BLK but I don'r see why it couldn't be.
