Thor Howa L/A 1 Piece Base 20MOA

The Thor Howa L/A 1 Piece Base 20MOA provides a one-piece mounting platform for compatible Howa long-action rifles. Its 20MOA configuration adds built-in elevation cant, which can help preserve usable elevation adjustment when setting up an optic for longer-range shooting.

Thor Howa L/A 1 Piece Base 20MOA

A one-piece base combines the mounting points into a single platform. As a result, it gives the scope rings a continuous mounting surface and allows flexibility when positioning a compatible optic. However, correct receiver fitment remains essential.

The long-action designation matters because Howa rifles use different receiver configurations. Therefore, confirm that your rifle has the standard Howa 1500 long-action receiver before selecting this base. Do not assume that a short-action, Mini Action or Superlite base will fit. The EGW Howa scope-base fitment guide explains the differences between receiver types and available mounting configurations.

The 20MOA angle inclines the mounting platform to provide additional elevation bias. Consequently, this configuration may benefit an optic used at longer distances, particularly when its internal elevation adjustment is limited. However, the best choice depends on the scope’s adjustment range, intended zero distance and shooting requirements.

Before installation, check the ring interface and mounting hardware. A Picatinny rail, for example, accepts compatible Picatinny rings and some Weaver-style rings; nevertheless, confirm the interface on this specific Thor product before choosing accessories. Also, check that the base sits correctly on the receiver and follow the manufacturer’s screw-torque instructions.

For compatible mounting accessories, browse the Outdoor Guru rings and bases category. Finally, verify the rifle model, action length and mounting pattern before installation to avoid ordering an incompatible base.
