The GigaGaburevolver (ギガガブリボルバー Giga Gaburiborubā) is a red and blue version of the Gaburivolvers owned by Torin, invented by Yayoi to enhance the Kyoryugers' Gaburivolvers to access the Spirit Base once it is reintegrated into Bragigas. When Bragigas' Zyudenchi is inserted into the Giga Gaburivolver, Torin transforms into Kyoryu Silver. After Torin was killed by Dantetsu Kiryu, the Giga Gaburivolver was taken by him, who used it to become the second Kyoryu Silver.
In 2114, however, when the Kyoryu Silver powers are used by Ian's descendant, Icchan, the Giga Gaburivolver is not used, instead Icchan uses a standard Gaburivolver to transform into Kyoryu Silver with his team.
The same with other Kyoryugers, By shouting 'Brave In!" (ブレイブイン！ Bureibu In!), the totem Zyudenchi is inserted into the "mouthpiece" of the gun, Kyoryu Silver can transform by shouting "Kyoryu Change!" (恐竜チェンジ Kyōryū Chenji), then spin the cylinder, dance a bit, then announce "Fire!" (ファイヤ！ Faiya!) and shoots into the air, forming a Brave construct of the totem Zyudenryu's head, which flies around his Kyoryuger form, then stops behind him and "chomps" once, forming the suit, with a second one to form the helmet. To cancel the transformation the same with other Kyoryugers, Kyoryu Silver can eject his used Zyudenchi.
Though Kyoryu Silver never used the Giga Gaburivolver outside of transformation purposes, it can be assumed that when the cylinder is spun again after transforming, the Giga Gaburivolver will announce "Vamola" (バモラー Bamorā), allowing Kyoryu Silver to fire the Zyuden Brave Finish (獣電ブレイブフィニッシュ Jūden Bureibu Finisshu) attack. If a second Zyudenchi is inserted into the Giga Gaburivolver, it will announce "Vamola Mucho" (バモラームーチョ Bamorā Mūcho) to fire a stronger version of the Zyuden Brave Finish.
It can also be assumed that when the Giga Gaburivolver announces "Metcha Mucho" (メッチャムーチョ Meccha Mūcho) after a second Zyudenchi is inserted after pulling on the Giga Gaburivolver's hammer to make the "mouth" open and close, Kyoryu silver can enter his Armed Mode (アーマドモード Āmudo Mōdo) by spinning the Giga Gaburivolver's cylinder along his right arm with the announcement "Armed On!" (アーマドオン Āmudo On), where he is given gold spiked armor on that arm, though without a personal weapon.
The Giga Gaburivolver can also be inserted into Gigant Kyoryuzin to control the mecha.
