When selecting a red dot for your TX22 Compact, here are a few key points I’ve learned from years of shooting and mounting optics:
1. Do I need an adapter plate for the TX22 Compact?
No, not if you choose an optic with the RMSc footprint. Holosun 507K, Vortex Defender CCW, and Swampfox Sentinel mount directly.
2. Will a red dot change my point of impact?
You may need minor adjustments, but once zeroed, red dots remain accurate even after hundreds of rounds.
3. Can I co-witness iron sights with these optics?
Yes, most micro red dots sit low enough for partial co-witness. The 507K and Sentinel do this perfectly.
4. What MOA size is best for target shooting with a TX22?
A 3 MOA dot is ideal—it offers a good balance between precision and speed.
5. How long do the batteries last?
Most modern optics provide thousands of hours of life. The Holosun 507K, for example, lasts up to 50,000 hours.
6. Is it hard to install a red dot on the TX22 Compact?
No. The slide is pre-cut for RMSc optics. Just ensure proper screw length and torque specs.
7. Which red dot has the clearest glass?
The Leupold DeltaPoint Pro and Sig Sauer Romeo-X Compact have the best optical clarity in this list.
After testing and comparing numerous optics, I confidently rank the HOLOSUN 507K as the overall best red dot for Tx22 Compact due to its rugged design, long battery life, and perfect RMSc fit. The Swampfox Sentinel is the best value option for budget-conscious shooters, while the Sig Romeo-X Compact delivers high-end performance without the Leupold price tag.
Whether you’re using your TX22 Compact for target practice, training, or rimfire competition, pairing it with the right optic elevates your shooting experience dramatically. Pick the model that suits your shooting style, and you’ll see immediate improvement in accuracy and enjoyment.
