Description
Sig Sauer Taper Cap Features The Sig Sauer Taper Cap is engineered to adapt the factory tapered 5.56 NATO barrel shoulder to a standard 90-degree shoulder ensuring muzzle devices thread on evenly and seat properly for a flush secure and uniform fit. This straightforward upgrade eliminates the inconsistency and potential accuracy loss that can result from an improperly seated muzzle device or suppressor on MCX and M400 platforms. The 1/2x28 thread pattern is the industry standard for 5.56 NATO rifles ensuring broad compatibility with suppressors and muzzle devices from major manufacturers. The 5.56 NATO taper cap features an anodized black finish that resists corrosion wear and the heat generated during sustained fire. Installation is simple and requires no gunsmithing making this a quick and practical upgrade for any Sig Sauer 5.56 NATO owner. Whether running suppressed or with a standard muzzle device it ensures a consistent properly seated fit every time.
