I've always been a fan of the best possible materials for a build, whether it be a pistol or a rifle. I'm a little new to all the manufacturers out there so I could really use some friendly advice. I'm looking to build a 5.56 AR Special Purpose Rifle with a 20"- 24" bbl from the ground up. Cost is not a factor, and I'm looking for 1/2MOA if at all possible. I'm not all wrapped up about rails and all that tactical stuff, but I do not want a stainless barrel. I already have the lower covered, so all I'm worried about is the upper. What would be the very best quality parts I could use? So far I'm looking at a Krieger Barrel, a Young National Match bolt and carrier, and Hogue furniture. Any ideas or recommendations would be greatly appreciated. Thanks!

THAT'S NOT AS MUCH AS "CONVENTIONAL WISDOM" (WHICH IS NEITHER, MAKING THE TERM POSSIBLY THE ULTIMATE OXYMORON) WOULD DICTATE. SO, WHY HAUL AROUND THE EXTRA LENGTH AND WEIGHT WHEN YOU CAN HAVE A FAST HANDLING, TIDY 18" PACKAGE:

MY PERSONAL OPINION IS THAT IF YOU CAN'T DO THE JOB WITH AN 18" 5.56MM SPR, YOU NEED TO MOVE UP TO A LARGER CALIBER WITH A SUPERIOR BALLISTIC COEFFICIENT.

Man that is a wonderful reply Wes, good stuff as I agree completely with the assessment and imho, you can only have a spr if you run and 18"....I am not a fan at all of how the lines are blurred these days with folks calling 20" guns spr's.
