Hello All, new to the Forum and my soon to be AR10. I'm buying a brand new/unfired Sig 716i Tread BDX Combo rifle from a bud at work. I handled the gun, simply fantastic quality built rifle. The trigger was beyond crisp, but heavy as hell! I know the 308 like .22 rimfire, needs a robust strike on primer for reliable ignition. What AR10 specific triggers are you guys using, that are giving 100% reliable ignition in your guns? I ONLY shoot brass, no matter the caliber. Thanks for any help.
