A German company called Ergosign (an acronym made of the words ergonomic and design) manufactures adjustable shotgun stocks called EvoComp. The stocks are available both in a standard configuration and also have a variety of options including lightened versions, different grip styles, and even custom made grips to exactly fit any particular shooter’s hand.

The standard version of Ergosign stock (the top image of this article) has an adjustable length of pull as well as cheek rest and butt plate adjustability in any imaginable direction and angle.

If the weight of your shotgun is something extremely important for you, then there is a skeletonized version (above image) which reduces the weight by 15 grams (about 0.5 oz). Not a significant weight reduction to me, but possibly even that matters for competition shooters. If you want it to be lighter than that, there is a version called Ultra Light (image below) which has more cutouts and fluted metal parts reducing the weight by 50 grams (1.75 oz). The overall weight of the Ultra Ligh stock is 780 grams (27.5 oz).

The modular construction of the Ergosign stock chassis allows making its basic configuration with some preset dimensions. For example, it can be made with a cheek rest located higher or lower than in the standard version and still have the same adjustability. Or it can come with a longer or shorter basic length of pull etc.

Here is the shotgun model list for which the Ergosign stocks are available:

The MSRP for the standard configuration stock is around €2000 (about $2365) – a little more or less depending on the configuration.
