FAQ – Zenitco B‑19 Gas Tube Cover
Q: Can I install the B‑19 without a Zenitco lower handguard?
A: No. The B‑19 is designed specifically to mount only on Zenitco-manufactured lower handguards. It will not fit properly on stock or aftermarket non-Zenitco parts.
Q: Does the B‑19 interfere with iron sights?
A: No. The rail’s low-profile design allows for full use of your rifle’s factory sights even when optics are mounted above it.
Q: What optics are compatible with the B‑19 rail?
A: Any compact red dot or reflex sight designed for 20mm Picatinny rails, such as Aimpoint Micro, Holosun, or Vortex micro sights.
Q: Is the finish durable?
A: Yes. The D16T aluminum is hardcoat anodized for corrosion resistance and durability under field conditions.
Q: What if I want to remove the rail later?
A: The B‑19 can be removed easily using standard tools, making it a flexible upgrade option that does not permanently alter your firearm.
