Skeleton version

Compared to the standard version the middle section of the stock is skeletal. This provides the stock with an even more technical appearance and reduces its weight by approx. 15 grams. The skeleton version is available for a stock length of 340-390 mm and 360-430 mm.

Skeleton version Ultra Light

Compared with the previous skeleton light version (see above), we could reduce the weight of the EvoComp Ultra Light by another 50 grams. This alteration provides the stock system an even more technical appearance. If a shooter requires an extra light stock (with a total weight of e.g. 780 grams), we have the possibility to use an appropriate wood and to adapt it to very light barrels – to reach an optimal adjustment of the shotgun’s balance on the fully adjustable Ergosign EvoComp.

Clamping collar +10 mm for heightened ribs of approx. 10-15 mm

By mounting a heightened clamping collar of approx. 10 mm between the middle section and the comb the drop can be adapted to the heightened rib (e.g. Perazzi MX2000/3, MX10, Beretta X-Trap, Caesar Guerini etc.).

Clamping collar +20 mm for heightened ribs of approx. 20-25 mm

Our clamping collars offer the best possible flexibility in adjustment for shotguns which need a modified drop (even after the additional mounting of heightened ribs). Further differences in height can be balanced through the possibility of choosing heightened combs with its range of adjustment.

Clamping collar +30 mm for heightened ribs of approx. 30-35 mm

Version TR 1°

This version is particularly recommendable for shooters who have a short neck and a high gun position. The drop is adjustable from approx. 35-55 mm. The comb has been drawn for approx. 5 mm forwards, the drop is parallel to the rib at the front/at the back. Pitch 93° to 85° (Special version +4° is adjustable from approx. 93° to 81°).

Version TR +10 1°

In comparison to the previous system (TR 1°) the drop of the butt plate is adjusted by approx. 10 mm in height. This configuration can be used as a base for the MX2000/3 (and other shotguns with a heightened rib of 10-15 mm) in connection with a +10 mm clamping collar for a 20-25 mm heightened rib or with a +20 mm clamping collar for a 30-55 mm heightened rib.

Special version Perazzi MX2005 + 20 0°

On request of various double trap top shooters, we have developed further stock configurations with removable trigger group for the Perazzi production series. In this special version the complete back stock part is raised to the level of the barrel rib on MX2005, so that the drop is correspondingly adjusted. The result is that the recoil of the shotgun is straighter to the shoulder and that the muzzle jump is considerably more influenced by the pitch adjustment (in comparison to stocks in standard version).

Special version Perazzi MX2008 +30 0°

See above description, but adapted to the MX2008.
