the ARs F&F is typical strider, ie i dont think any are just "perfect" but all i have seen lock up good, i would say quality is good.
i have had a AR and a GB and imho the SnG or the SmF both make better knives to edc, the AR/GB's are really more at home in a belt sheath vs pocket carry, they are big, thick, wide knives which, to me, dont ride well in a pocket, the SmF is right on the edge of being too big/thick, but will work "ok", while the SnG is great in that role.
if it was me i'd get a SnG if ya intend to edc it in a pocket vs a sheath, but some folks do edc the AR/GB's and like 'em,
oh, and i like large knives and thats what i usually am carrying ie EKI CQC12/CQC8/spyderco Ti ATR/crawford kasper and perfigo/etc. but the AR/GB is just so thick and wide...............
