This is kind of an interesting question. The PC 15-22's have been around a long time and one thing I haven't seen is a thread where someone (anyone) brags about (or posts pics of) the great groups they're getting from their PC 15-22.

I think it's been pretty well established the "std" version 15-22 is a 3 MOA gun but the PC 15-22 owners seem to have remained amazingly silent about their guns' performance.
