So here's the deal. This spring I plan to head stateside to shoot prairie dogs for a few days. I hope this will become an annual trip. I want to purchase or put together a target upper to reach out quite far. I already have a decent lower with a 2 stage trigger etc...
I do have a stripped upper and most of the tools to assemble my own upper. I've never actually assembled an upper but from what I can tell it's not that difficult with the AR platform. The original plan for that upper was to put a shorty together but now I seem to want a long range upper.
So far I'm thinking a fluted barrel for cooling since it will be a lot of shooting. A handlapped barrel seems to be a standard for long range accuracy but I would hate to damage a really high end barrel by overheating it shooting pdogs. After the Pdog hunt I'd like to use it for some long range target shooting (F class or whatever class my AR would fit into).
I'm not sure on barrel length or if I should go with a rifle or mid length configuration. I'm led to believe the longer configuration is more accurate but I don't really know.
Ideally the upper would be heavy enough or have a muzzle break to minimize lift so I can see the pdogs go splat in my scope. I'm not clear on how a muzzle break may affect accuracy vs a recessed crown style muzzle.
I know DPMS and RRA have target/varming uppers but I'm not sure they are true match barrels. ATRS have Lilja barrels which sounds great but I have never seen one of their rifles in action. Getting a complete upper from them is sounding pretty good though...
I've done a ton of reading online but I"m looking for any additional advice from those who use their AR's to shoot out to 400 yards or even farther.
Thanks.
