Before everyone condemns Sabres' AUG barrels mine shoots WAY more accurate than my 1/7 FN FS2000 which both shoots same ammo and are both bullpups and both have a Micro Aimpoint on them (apples to apples).
The 1/9 Sabre will shoot all 20 rounds of Winchester Q3131A Israeli 55 grain or M855 62 grain and Lake City Arsenal 55 grain into 1.25 to 1.5" at 50 yards with just the Aimpoint.
I shoot at 2" black squares and it will even come close with Silver Bear cheap steel cased. It also shoots 75 grain HP's with no problems, where some 1/9 AR's don't.
The bore is hard chromed on mine too, it has been 100% reliable.
And the new guns cost more than I paid and come with one mag, mine came with 2 mags and a nice assault case that I use for it and the FS2K.
