Beretta Oversize Bolt Knob Features The Beretta Oversize Bolt Knob is built from polymer and designed to slip directly over the factory bolt handle on Tikka T3 and T3x rifles immediately increasing the surface area available for gripping during bolt operation. This larger knob makes it easier to run the bolt quickly and positively which is particularly useful for hunters wearing gloves or shooters running the gun fast in competition. The polymer construction keeps the added weight minimal while still providing a solid comfortable grip surface. Because it fits over the existing handle rather than replacing it outright installation does not require disassembling the bolt. A set screw holds the oversize knob firmly in place once installed preventing it from loosening or shifting during use. This simple installation method means the upgrade can be completed at home without specialized tools or gunsmithing knowledge. Designed specifically for the Tikka T3 platform the knob is sized and shaped to complement the rifle s factory bolt handle rather than looking like an aftermarket add on. For Tikka T3 and T3x owners who want faster more confident bolt manipulation this oversize bolt knob is a simple and effective upgrade.
