SBR Barrel length ?

[Dieseltech09]

Will there be any difference in the performance of an SBR AR15 regarding barrel length? I think I want to stay between 10.5" and 12.5 but will 2" in make any difference in the accuracy or anything else?. Im looking at the Noveske light weight or maybe the QCB stainless for my build.
Thanks

That's a lot of data! Does it summarize the findings somewhere? Just glancing at it, it woudl appear that accuracy is more effected by powder charge. Or you cna make a short barrel just as accurate as a long barrel if you build a load for it. Is that correct?

That is correct Jesse. For the most part, velocity is all that is lost with the shorter barrel.
