| I have an M16A2 with a bent buffer retainer pin, which allows the buffer to pop out when the rifle is disassembled for maintenance. I've never had this problem before, will this cause the weapon malfunction if it must be employed? Replacement parts are hard to come by here and I need to issue this weapon next weekend. I was able to come across some new pins but I'm having trouble taking off the buffer tube. |

Sorry but I'm unsure what your question really is...... Yes it will cause problem and should be fixed. If your having trouble removing the buffer tube I suspect it's "staked". Ya got two choices: 1. if you have the tools, place the lower in a vise and put your weight into it, shearing the staking 2. Dremel tool (careful here ya might un-neccessarily scar the lower As to parts....., there are parts for sell everywhere here : above, EE or the Industry forum I have a complete parts kits for almost every AR I own, you should too... then replacements parts are no big deal, simply go to the box and pull out a new buffer retaining pin. Mike ps - sounds as if your some sort of armorer....
parts and this knowledge should already be on hand..... |

To add to Wilson, Could be that the receiver extension was loctited in place. To solve this, use a torch on the receiver extension (about a 1" back from the receiver and preventing the flame from hitting the receiver), working the torch to heat up the tube only to about 650*, which will transfer heat down to the tube/receiver threads and break the loctite bond (you will smell a sweet smell as the loctite bond breaks). |
| Unfortunately the parts aren't there. Reserve units don't get the proper tools/schooling/support needed, especially Navy units. If I was in a state side location it would be a lot easier, because gunner's mates aren't "allowed" to break down a weapon past what maintenance requirements cards call for anymore, everything is sent back to Crane and replaced. I've been fighting for armorer's school for over a year now. Would be a complete different story if I was with the Seabees but unfortunately I'm in a law enforcement unit. Other than that, thanks for the help. |

I'm up here in NY so I cannot fix it for you. The rifle will run as long as the pin doesn't fall/pop out. I have a repair kit from CMMG that has that pin. The bushies do not stake the buffer tube nut, so once the stock loosens up that pin jams the rifle. My suggestion is to get yourself a parts kit for just this kind of emergency. |

you need a vise to remove the buffer tube, got one? also, the rifle will run fine without the buffer detent as it's only job is to hold the buffer in when the weapon is shotgunned. as long as the operator is aware of the issue it shouldn't be a problem until it can be rectified. |
