Hi
I own a High Pheasant - fantastic gun!
The standard MK60 (universal) is only available up to 30" barrels and can be had in grade 1,3 and 5 with 1/4 and 3/4 choke. The HP is 32" and fixed 3/4 and Full choke - the stock dimensions are slightly different and it shoots marginally higher than the standard gun, although not as high as say a MK38 trap. It comes in grade 5 only. It is available as a single gun although the majority advertised are sold as matched pairs.
In my opinion it offers very good value for money in both single gun and pair. It shoots and handles superbly with light for length barrels. It is not going to be everyones cup of tea because of the barrel length and tight choking, but I have used it for everything over the past year and really cannot fault it.
