    Looking at replacing my old tasco 4x32 scope on my ar15. I bought a NcStar Colt copy and sent it back to Optics World for a refund. But I have a buddy that will sell me his Nicon PROSTAFF 3-9X40 MATTE BDC for 100$. Is this a good scope to put on my gun that will imporve the results of my bad groupings of 8 inches at 100 yards? I may have another problem. When I bought my upper and built my gun on a PWA lower I bought it from a friend who had a [legal] machine gun in Florida many years ago. He was putting on a different twist for his gun and sold me his upper to build my gun. I have always wondered if the guns barrel was heated up too much and could this be why it seems like the gun will not shoot as accuratly as my Colt? Or is it the 29$ walmart tasco scope? The thing is I have had several of these cheap scopes on guns like my Remington 700 and they shot at 100 yards fine.

    if the barrel came from a class 3 that saw a lot of use the barrel might be worn out. a decent smith that is familiar with ar15 can tell you. but its something that has to be hands on.

    I don't think the bbl was shot out. I think he only said he put about 1000 rounds throught it before decideing to go with a different twist. I am sure he said it was a 1 in 9 and its chrome lined. It could be the scope. I have never been able to shoot spot on with it, so I got the NcStar and it was worse than the Tasco. I have a chance to put on a Nicon scope for 100 that is a fair optics for 100 yd. shooting. I just dont want to work on the wrong problem. If I need to repalce the bbl I can work on that. But I am not sure the bbl is the problem.

    One way to be sure. Take one of the scope off your Remington 700 and try it with your AR. That should determine if it's your gun or your scope. But I would go with the Nikon or maybe your buddy will let you try it to see if you need the scope.

    I think your right but its a good buy on the Nikon. Here is the gun as it is now. Before I remove the old Tasco.
