| I am looking for is a reputable individual or store front business that will build a rifle for my brother in Houston. He has a stripped lower, LPK and a stripped upper receiver. Thanks. |

Quoted:
Its pretty easy to assemble the lower yourself..... Just use the How to in the build it yourself section..... While I agree completely with that, he does mention that he has a stripped upper, and at minimum that means you need a few tools (AR barrel wrench, torque wrench and head space gauges probably at minimum) and a bit more knowledge than assembling a lower. Quite reasonable for someone to want a little assistance at least for doing it the first time. I was the one who suggested he post here. I'd be willing to help him if he was in the Austin area, but I was hoping someone local to Houston could give him a hand or point him in the right direction. |

Headspace gages with an AR? No, not needed, nice to have but these days they simply aren't needed.
What you will need is a good upper vice block, like a DPMS Claw and a torque wrench. After you do enough, you hardly even need a torque wrench. I do most of mine by feel and visual inspection now. |

Call me paranoid, but I'd never fire an upper I assembled that I hadn't checked with GO/NOGO gauges... The DPMS vice blocks are the ones I have too. If you wait until MidwayUSA has them on sale, the Forester head space gauges aren't that expensive, worth it if you plan on doing more than a couple of uppers, and better safe than sorry I think. |

Like has been said, you don't need headspace gauges... If it is far enough off to cause a problem, the bolt will fail to lock and will not permit the hammer to strike the firing pin. The design of the rifle is such that it is not necessary. The barrel extension is integrated into the barrel... the bolt locks into the extension... there is no way for two new parts made to the spec to not headspace properly, that would still allow the rifle to fire. |

I'm not out to undermine safety, so if you feel its necessary, more power to you. I own headspace gauges but only use them on my surplus rifles and bolt action rifles. Its a very rare event to have headspace be an issue on say a .223 or .308 modern AR rifle and for me its just risk assessment, I simply don't bother. I've built about 5 AR's all the same way, 2 being .308 and have yet to even see headspace being an issue. With modern machining, as long as you use a reputable manufacturer, you should be golden. If you really are worried about it, a simple field headspace gauge should put your mind at ease. I wouldn't bother with the other gauges unless you plan on building a non-AR rifle or testing surplus equipment before firing. Just my opinion though, your results may vary. |
