My wife got a Mk III Hunter for her birthday. We shot it at the range a couple of weeks ago and I thought it was pretty good out of the box. There were 3 guys at the range shooting mk III's as well. They told me they had done the bushing replacment and had a guy in town remove round in chamber indicator on the side and replaced it with a milled piece of metal to close the hole. They all had some kind of red dot sites and were shooting 200 yrds with insane accuracy. I got to run a mag through one of these modified Mk III's and was quite impressed. The wife doesn't want to modify hers, so i've got a mk III on my to buy list. I was really impressed.
