Why do we include a shim kit with our Aluminum Bottom Metal/Trigger Guard? During our exhaustive testing, we found that factory Tikka stocks are not uniform regarding the bottom metal/trigger guard well. In some instances, when an aluminum bottom metal/trigger guard is installed on a factory stock, the magazine does not seat correctly. This issue rarely arises with factory plastic trigger guards because the plastic guard flexes, which negates manufacturing inconsistencies and allows the magazine to seat. Aluminum is more rigid than plastic, so it does not flex. Our solution? Include a shim kit that allows an end user to shim out the Trigger Guard in .010 inch increments.
We have tested dozens of Tikka T3/T3X Lite and Tikka T3/T3X Hunter stocks. Some stocks did not need a shim at all, and some stocks needed to be shimmed out .03 inches.
Interestingly, some factory Tikka rifles that still have the factory plastic trigger guard have also benefitted from a .010 inch shim. For this reason, we offer a stand-alone shim kit as well.
Uneasy about swapping out the Trigger Guard? Ship it to us, and we will happily install it. Don't hesitate to contact us if you have questions.
