They are a good deal only if you really want all the included gubbins and are happy with the products offered.
If however you want a better 'scope, different make of moderator, upgraded stock, don't need a third party plastic magazine system or a cheap copy of a Harris bipod then you may be better off negotiating with your dealer to supply only the pieces you want.
The great thing with Howas is that you can choose every part individually, starting with a barreled action (which all come with a hard case and picatinny 'scope rail included), then a wide choice of stocks (or you could got to a third party instead) and all the other accessories from the Highland Outdoors catalogue, and get the best combination to meet your needs. They call it their "dream it build it" program.
Your dealer should still be able to offer a good discount on the sum of individual prices.
