Adjustable Shotgun Stocks by ERGOSIGN of Germany

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.

    The name isn’t an acronym, it’s a portmanteau. 😉

    TFB should order this and the TSK and provide us a full comparative review.
    And please, fit it on a Perazzi.

    Am I reading that right, that the stock alone starts at around $2300 USD??? BWAHAHAHA. I wouldn’t pay that much for this stock if it came with a Benelli M4 attached to it.

    I don’t always say this, but in this case I’ll wait for the Chinkie ripoff that costs ~$200.

    Great takes so far on this. However, I’ll add mine. I think this is a great looking piece of hardware, a little high brow for me, but then nothing I own has been used to win gold medals. I bet there are enough people out there to keep this afloat, but this stock has only been on the market for 8 years so who knows.
