^^So does this mean that only the lower has to be one of these brands and you can use any other parts available? or just any parts from these (4) manufacturers?
Here's an interesting review of the HK > http://looserounds.com/2014/08/17/hk417-mr762a1-review-and-test/
Does weight matter to you?
The JP LRP 07 would /should be the most accurate.
The DPMS SASS would be the cheapest.
The HK, see the above review.... ::)
The best overall for accuracy & dependability.... If I had to put my ass on the line, out of these (4) I'd carry the Armalite Super SASS.

These are just my opinions & you know what they say about that....
Oh gawd, someone's head is getting so big it's gonna explode! Wait for it, he'll be along shortly..... <lmao>
