I have a Delta 5 Pro in .308. I checked my zero last week and it put five rounds into ~5/8" at 100 yards. I like it. I haven't had any problems with it.
I bought mine because I had a list of things I was looking for - kind of typical "custom" things I would want in a rifle - and it had them all. Chassis, threaded muzzle, good trigger, DBM, caliber, etc.
