| Picked up an ORC a few weeks ago, but didn't have time to fondle it and make a comparison to a regular AR before my R&R was up. I found a few bits and pieces of info here but I just want to make sure I have things straight before I start having parts sent to the house. The ORC accepts any regular AR stock / receiver extension as long as I use a .308 specific buffer and spring. Do I have this right? |

I found a few bits and pieces of info here but I just want to make sure I have things straight before I start having parts sent to the house. The ORC accepts any regular AR stock / receiver extension as long as I use a .308 specific buffer and spring. Do I have this right? Not entirely. If using a collapsible stock designed specifically for a .308, then a .308 carbine buffer and spring will work. A rifle length buffer tube for an AR15 will also work, you just need a heavy buffer and an AR10 spring. You can use a collapsible stock made for an AR15, but you will need a Slash .308 buffer and an AR10 spring. His buffer is heavier and shorter than a standard .308 carbine buffer. This allows for sufficient length of recoil for proper extraction. If you just tried to run a standard .308 carbine buffer in an AR15 carbine buffer tube, the buffer would bottom out before a full cycle of the bolt could be made and would result in malfunctions. If I am wrong - someone please correct me, but that is my understanding from what I have researched. I am currently using a Slash buffer and AR10 spring with a UBR stock in my MA TEN build. |

If you use the DPMS 308 carbine buffer you can use any standard AR-15 buffer tube. It is when you use an Armalite 308 buffer (which I believe is a standard length carbine buffer) that you use a 308 specific carbine extension. The Slash buffer is the same length as the DPMS 308 buffer. |

The Slash buffer is the same length as the DPMS 308 buffer. Many prefer the slash buffer over the DPMS as it is much heavier. Most (including myself) believe the DPMS rifles are overgassed and the heavier buffer helps. I prefer the 308 carbine reciever extension, it allows the use of standard ar15 carbine buffers. This gives you more buffer choices and you can use even heavier buffers if your rifle prefers them. |

Thanks for the advise, let's see if I have this straight now. Full length AR tube (I want a fixed stock), .308 carbine buffer (DPMS or Slash), Armalite .308 carbine spring. Thanks again. If you're going to use a fixed stock, you'll want a regular Rifle Reciever extension, AR10 Rifle Buffer, AR10 Buffer Spring. If you like I can add links. AR10 Buffer for Rifle Receiver Extension AR10 Buffer Spring EDITED: added links |
