Is it necessary to have a buffer and buffer spring in my AR-15? I recall hearing that semi-autos don't require the buffer/spring, only full-autos do. They help the full autos cycle correctly. Is this true? The reason I ask is... I have everything to build my new AR, except those two parts. Thanks. |
Ummm. Seriously? I'm not even trying to be an asshole, this time. You are really being serious? Well, the answer is no. The short answer is you have to have something to push the bolt group back after firing a round. |

Thanks for the info. It didn't make much sense to me either. But, I was watching the AIG dvd on AR-15's and I could have sworn the dude said the buffer and spring were not necessary on semi-autos. he Maybe I just misunderstood the guy. |
The good news is that without the spring there's be no way to chamber a round from a magazine. It could still be fired if the shooter manually dropped a live round into the chamber, pointed the muzzle at the ground and shook it a little to get the bolt to come forward then used the forward assist to get it to close. Anybody so barin dead that they'd go through all that effort without realizing that something's wrong deserves what happens when they pull the trigger. |
You should not attempt a build until you understand how a Stoner system rifle works. |
I own this video. Bob Dunlap . . .master gunsmith . . .was referring to the buffer weights specifically. His point was they aren't needed for semi-auto, but in full auto they help control the cyclic rate of the weapon. I can understand your confusion . . . that guy is agonizingly dull to listen to. Did you catch his joke about using a hand grenade to disassemble the FSB? It was apparent only by his long pause and mindless stare into the camera. I laughed out loud . . . And I'm still not convinced that his recommendation of using Simple Green to clean the weapon is a good idea. I'd hate to see that water based cleaner get into some crevices and start a rust issue. However if you look at his fingernails you can understand his desire to use a friendly solvent. That guy must clean a lot of guns! |
| I believe Simple Green, while a good solvent that is "friendly" to people, leaves behind a chemical salt residue that can damage steel and is very bad for aluminum. There is an "Extreme Simple Green", which has corrosion inhibitors that are supposed to mitigate the problem, but using a corrosive product which has had its corrosive propertis lessened seems like a bad idea when there are products made for guns available, some of which are supposed to be pretty safe. |
Therefore you would read my How it works writeup. |
What on earth are you talking about? Can you elaborate? |
I think you get the hint, the answer is yes they are required, and as phylodog said, please don't even think about trying it. The result would be very bad for the rifle, and even worse for you. |
Awww...  That's no fun. Quit being so practical. To the OP, go ahead and try it. Make sure a friend is video taping it. Post the resulting video on you-tube and link it here. If everyone else is like me, they also like to laugh at people injuring themselves. |
