All that remains of my Delta rifle is the preban lower that is now used in a M4 type carbine. It was a BIG disappointment. My SP1 would outshoot the thing badly. The scope was a cheap Tasco and the mounting screws stripped out. I replaced the Tasco with a Zeiss. I replaced the mediocre Colt 1:7 barrel with a match quality 1:9 and put in a JP trigger. I added a really cool adjustable stock and free floated the barrel. It was now a really good looking gun. It still was outshot by my M4 tricked out gun. I probably should have kept it as a "collectors item", but the thing was overrated. You would be better served with a flattop AR15 than the "Delta". Just my opinon. Watch-Six
