I am trying to spec out my next AR15 build. I have the lower figured out, but I'm having trouble with the upper. Can you guys/gals tell me which manufacturers make an upper that meets these specs... 14.5" barrel with permanent flash hider to make it 16" legal. 1:9 twist rate chrome-lined barrel M4 feed ramp M4 barrel cuts A3 flat top receiver I have found several that were close, but none seem to be exactly what I am looking for. Thanks in advance for all the help. |

Actually, I just checked Sabre Defense's website. They offer it in 1:7, 1:7.5 and 1:10. No 1:9. I know Bushmaster makes good stuff, but I was hoping to find one a little less expensive. They want $725 for that upper. Then again, that is a complete upper including A3 carry handle, but I was still hoping to find something for less. Any other suggestions? The reason I do not want to change the twist rate is that my current AR is 1:9 and I'd like to not have to worry about a particular bullet weight doing well in one and not the other. |

I think the thing that's killing your choices are the M4 ramps and barrel extension cuts. A lot of folks here feel that they are unnecessary, similar to KNS anti-rotation pins, and that it is merely a gimmick to sell "special" rifles. If you cut the M4 requirement out of your upper, you will open up your shopping choices greatly. |
