Hello all,
You guys are an incredible resource to the Do-It-Yourself Junkies!
1) I am curious to know, if some or any of various AR Uppers are compatible with one another. For example, could a stripped upper for a regular 5.56 also receive the barrel and bolt/bc of a 6.5mm grendel? Or 6.8 SPC? Or are separately machined uppers required for each additional caliber? Is this a stupid question?
2) Also, where is a good place to itemize ALL of the parts necessary to complete an upper build in 6.5mm? I would like to build a 6.5mm AR capable of reaching distances (
accurately reliably) upto 1000m. Not that I will be able to hit shit that far away, but to say that my rifle can would be nice.
3) One last thing, What is the optimal barrel length for distance shooting using the 6.5mm grendel. I can find tons of load data, but am looking for a performance breakdown on different barrel lenghts in order to optimize.
Thanks for the help folks!!!
