| Don't take this as some sort of Black Rifle bash, but why did Stoner design the guns with the Buffer Tube? There are many other .223 gas op. combat and/or sport rifles out there that don't use this device, and I've always wanted to know why it's needed. The thing prevents us from having a true collapsable stock, so what's the up-side to it? Improved cyclic rate? |

needed something to re-set the bolt/carrier after firing the gas sysetem pushes the bolt/carrier back, which bounces off of the buffer assembly and the cycle is complete guess he wanted to make it different and unique and i also bet that it helps in making the AR more accurate than other semis or maybe he like the 'spoingggg' noise |
If you want a real side folder for an AR check out ZM Weapons, they're pretty nice but expensive as hell. And who knows how reliable, they work simliarly to a AR180 or PARA FAL. |

cool  that made sense |
| By keeping the spring out of the action it is pretty much immune to the effects of heat and the damage it can do as far as ruining the temper. It is pretty well sealed against mud, dust and grit and if one has to unjam the bolt and carrier for whatever reason it is not acting against the operator as long as he can seperate the upper and lower. It can also be big and long which gives it added strength. I have never really heard of one being "broken" but have seen a few other makes where the spring broke in two after much use. |

It's part of the straight-line recoil management design of the rifle. The bolt carrier travels in line with the bore's axis, and compresses a weighted (that's the buffer) spring. This slows the bolt carrier while it stores energy to return it to battery. Since it's all in line with the bore's axis, there's less muzzle rise per shot, and since most of the mass of the system-everything but the carrier key-is in line with that axis, the whole system is very smooth. contrast that with an AK; they rise a lot, and when you look at the mechanical design you see why. Most of the bolt carrier's mass is ABOVE the line of the barrel's axis. This puts the inertial energy above the barrel, and leads to more muzzle climb than it would otherwise have. While I don't have an AR in 7.62X39mm, I understand that such ARs don't rise like AKs do. |
