Re: Izhmash Russian Dragunov Tiger rifles
While the PSL-54 and Tiger type rifles are different in some respects, the pros and cons are pretty similar.
I have shot two different Tigers and several different PSL-54C rifles and the accuracy is what I would deem acceptable for a "battle rifle" but not for a precision, DM, or "sniper" rifle (at least at longer ranges). Both platforms, on a good day, will get 2-3MOA (maybe slightly better, but not MOA or better). I have seen the same claims from folks that KingKong mentioned about sub-MOA accuracy, but never any hard evidence of it and certainly not in my presence or with me behind any of the rifles.
I know very little about any type of gun laws or restrictions in New Zealand or what you can and can't own or obtain, but if you want a semi-auto precision rifle, there are commercially available rifles that will achieve MOA or better accuracy out of the box with less financial investment.
