Tca 2050R Cross-Slot Steel Base Encore

The Thompson Center TCA 2050R is a one-piece steel scope base engineered specifically for Thompson Center Encore firearms. If you're mounting optics to an Encore platform and need a solid, no-fuss foundation for cross-slot rings, this matte black base delivers straightforward reliability. It mounts directly into the factory-drilled holes on your barrel, so installation is as simple as centering it and torquing the screws to spec—no gunsmithing required.

Built from steel and finished in matte black, the TCA 2050R is designed to pair with cross-slot ring systems and handle the recoil impulses of centerfire rifle cartridges. The single-piece construction eliminates the flex and potential misalignment that can occur with two-piece bases, giving your scope a stable platform from shot to shot. Whether you're zeroing for hunting season or dialing in at the range, a solid base is where accuracy begins.

Installation is straightforward: align the base with the factory holes in the barrel, insert the screws, and tighten to 25 in-lbs. Keep a torque wrench handy and don't over-tighten—25 in-lbs is firm enough to hold under recoil, but excessive force can strip threads or crack the base. Once mounted, your cross-slot rings will nest securely into the grooves, keeping your scope locked in zero.

Frequently Asked Questions

Will this base fit my Thompson Center Encore?

Yes, the TCA 2050R is designed for Encore firearms and mounts into the factory-drilled holes in the barrel. Confirm your rifle has the correct mounting holes before ordering.

What rings do I need with this base?

You'll need cross-slot rings that match the base's cross-slot design. The base and rings work together as a system, so verify ring compatibility before purchase.

How tight should I tighten the mounting screws?

Tighten the screws to 25 in-lbs using a torque wrench. This is firm enough to hold under recoil but not so tight that you risk stripping threads or damaging the base.

Is gunsmith installation required?

No. The base mounts directly into your Encore's factory-drilled holes. You'll only need a screwdriver or hex key (depending on screw type) and a torque wrench to complete installation.
