The thumb rest was developed to take advantage of the permissible total height of 45mm of the IPSC Standard Box*. Together with an optimization of the shape an increase of the contact area of plus 10% was achieved when compared to the original TSO thumb rest oftentimes retrofitted, thereby enabling better control of the gun.
The checkering was improved to increase grip while allowing for sufficient surface to allow for reliable adhesion of grip tape if so required.
The thumb rest is made from high-strength, black coated Aluminium, conforms to the standard CZ hole pattern and is supplied with two mounting bolts.
Tested during training, local matches, the regional and national Austrian IPSC Standard Divison Championships 2018/2019 as well as the Mosquito 2019 and the Extreme Euro Open 2019.
MADE IN AUSTRIA
* If a larger TSO magwell is used a minor modification may be required to maintain 45mm of height. Following installation, a cross check in the IPSC Standard - box is recommended!
