NOTE: Before installing a moderator, it’s essential to confirm that the barrel nut thread is correct and compatible with both the rifle and the moderator, particularly when using Hausken products. Hausken moderators are manufactured to precise thread standards, and any mismatch in diameter, pitch, or thread direction can result in poor fitment or misalignment. Ensuring the correct thread and material selection allows the moderator to seat squarely against the barrel shoulder, maintain proper bore alignment, and be installed securely, resulting in safer operation and optimal performance.
