I have done a fair amount of research on this but can't seem to find the right answer. Or at least one that fits my specific question(s)
http://img.photobucket.com/albums/v428/QikStik/Guns/IMG_6390.jpg I plan to purchase this VERY BASIC Bushmaster AR-15 A2 .223/5.56 Shorty Carbine w/ heavy 16" barrel. It also has a standard "non-adjustable" stock. I will want to change to a collapsible stock. Here are my questions:
Thanks in advance...sorry for the rookie questions!! |

Does my current stock have a buffer tube that can be re-used with an aftermarket collapsible stock?
No. In addition to the stock you'll need a new tube, buffer, spring, end plate, and castle nut. I am pretty sure I read somewhere that all Bushmaster stocks are "commercial", and not "mil-spec" Is this correct?
Bushmaster does use commercial carbine stocks and buffer tubes. It doesn't apply to what you have now. So with my configuration, as described above, what do I look for when researching collapsible stocks to replace my current stock?
First figure out what you want in a stock; storage, cheek weld, weight, price, etc. You can buy most stocks in a kit. You'll get everything you need and should save a little money. I would recommend buying a mil-spec kit. You'll have more options for the stock and they are supposed to be stronger than commercial tubes. |
Great info, but just to clarify...
I have been looking primarily at the Magpul stocks. Any other recommendations are welcome, and why you recommend them would be appreciated! |

Yes Correct Just carbine and rifle. Get the carbine for an adjustable stock I have been looking primarily at the Magpul stocks. Any other recommendations are welcome, and why you recommend them would be appreciated! Bravo company usa (at the top of the page) currently has a great deal on vltor stocks and assemblies. Better than the magpul offerings in the same price range (in my opinion) |

Your rifle will not function if you try and reuse your rifle length buffer and spring. The carbine and rifle buffer tubes are of different length. Carbine being shorter Just not enough travel.
ETA as long as you purchase a ture mil-spec tube it is stronger than the comm ones, some cheap mil-spec tubes are mil-spec in dims only and not manuf. |

Hi Mac.
A collaspable carbine stock buffer tube is 2.25" shorter than a rifle stock buffer tube. The BCG has to still move rearward 3.375" to cycle. A carbine buffer is 1.375" shorter than a rifle buffer, and almost half the mass. A carbine buffer spring is 2" shorter than a rifle buffer spring. With the carbine buffer tube being shorter it requires a different compression configuration. Hence a shorter buffer and buffer spring. That whole 10lb. of shit in a 5lb. bag thing. |
