Can some one please educate me on the issue with buffers in AR10 rifles? Is the issue that folks are swapping calibers, barrel length and stocks far beyond the manufacturers initial intentions and its created cycling problems? I have a LMT MWS 260 with a A2 stock. It was originally a 308 with collapsable stock. Should I be getting a new buffer and spring? |
| When switching stocks from a carbine to a Rifle you will need a different style buffer and spring. As for calibers, I can't help you. Maybe ask Slash at www.heavybuffers.com |

It was originally a 308 with collapsable stock. Should I be getting a new buffer and spring? I don't know if the LMT is an Armalite pattern rifle or not. But on my Armalite pattern rifle, I went from a rifle buffer and buffer tube on a 308 and switched to a carbine buttstock so i got the carbine buffer and carbine buffer tube. The buffer and buffer tube are dependent on the stock and not the caliber; at least that what it was in my case. |

Email me if you have any questions. |

From the AR10 FAQ here.
Will a AR15 (CAR) stock fit on a AR10?
YES (with caveats) you will need to use either the carbine AR15 buffer tube with a AR10 spring and a shorter (slash's) AR-10 buffer (for the longer AR10 BCG), OR put a AR15 stock on the AR10 buffer tube BUT it will not collapse all the way-see below for pics. The A2 stocks are the same, the AR10 rifle buffer is a little shorter in the AR10 rifle-see pics below I would recommend a buffer from slash (first choice) or a AR10 rifle buffer, the AR10 rifle buffer is 3/4 inch shorter than a AR15 rifle buffer. The .308/7.62 bolt is 3/4 inch longer than the AR15 bolt. You need to compensate with a 3/4" longer RE or 3/4" shorter buffer. |

The AR15 car and AR10 car RE are not the same, the AR15 are 3/4" shorter than the AR10.( the buffers are the same lenght, but the AR10 are heavier and the springs are too) The AR15 and AR10 rifle RE are the same,but the AR10 uses a heaver buffer and spring |

The AR10 buffer weighs 5.4oz vs the AR15 buffer at 5.2oz |

The AR10 bolt carriers are in fact longer, so they penetrate more into the RE, and have a longer bolt throw as well for the longer cartridge length. There is a thread that covers all this somewhere, but here are all the variations I'm aware of: SR25/DPMS/Armalite pattern rifles w/ AR15 rifle-length receiver extension, AR10 rifle buffer, AR10 rifle spring SR25K carbines with very short, nylon buffer, carbine RE, heavy recoil spring DPMS .308 carbines w/ AR15 telestock receiver extension, DPMS short AR10 carbine buffer (shorter than AR15 buffer) Armalite .308 Carbines w/AR10 mid-length receiver extension (longer than AR15 carbine, shorter than rifle), normal-length but heavier carbine buffer, heavier recoil spring Vltor A5 carbine receiver extension, mid-length buffer, mid-length recoil spring. I believe the A5 is similar in length, if not the same, as the Armalite AR10 carbine RE, but has a longer buffer for AR15's. |

It's going to be difficult for anyone who doesn't already know to understand what you are trying to convey.Every AR10 rifle-length buffer I have seen from Knight's, Armalite, DPMS, and others is shorter than an AR15 rifle-length buffer, since they all use AR15 rifle receiver extensions.

There is some good buffer info (with pics) in the FAQ thread in this forum. |
