When Consistency Counts

Engineered to eliminate the accuracy loss caused by metal‑to‑metal coupling, this premium TPU 95A insulator isolates the moderator from the shroud to preserve your barrel’s natural harmonic behavior. The result is a cleaner node, tighter POI stability, and a smoother, more predictable shot cycle — all without touching your tune.

Precision‑printed with a firm, alignment‑safe compression profile, the insulator breaks the vibration path that normally feeds resonance back into the barrel system. No rattle, no ring, no wandering groups. Just stable, repeatable performance shot after shot.

Key Features

• Harmonic Isolation — Prevents moderator‑induced vibration from entering the barrel system

• POI Stability — Reduces vertical spread and wandering groups

• Refined Shot Cycle — Eliminates metallic ring and resonance transfer

• Alignment‑Safe Fit — Firm, even compression without forcing the moderator off‑axis

• TPU 95A Construction — Durable, temperature‑stable, and tuned for the ideal balance of rigidity and damping

• Drop‑In Installation — No tuning changes required

Built for shooters who demand consistency — and tuners who understand why it matters.
