Find the right bolt or barrel for your firearm at TALOS Defense. Our range covers AR-15 / M4 barrels in match-grade, government-profile, mid-length and hunting configurations (lengths from 10.5" SBR through 20" service rifle, in 5.56 NATO, .223 Wylde, .300 Blackout and other AR-platform calibers), AR-10 / .308 barrels for designated marksman, hunting and precision builds, bolt-action precision barrels in match-grade configurations from leading aftermarket barrel makers, HK platform barrels and bolts (G3, MP5, HK416-pattern components from CK Corp and other top suppliers), pistol barrels including match-grade, threaded and conversion barrels for Glock, Sig Sauer, 1911 / 2011 and other major platforms, AR-15 bolt carrier groups (BCGs) in mil-spec, nickel boron, nitride and titanium configurations, pistol slide assemblies in standard and optic-ready configurations, and specialty barrels (heavy contour, fluted, threaded for suppressor use, integrally suppressed where legally available).

We stock barrels and bolt components from leading manufacturers across precision rifle, modern sporting rifle, HK platform and handgun applications — with options across material (chrome moly, stainless steel, melonite, nitride), profile, twist rate and chamber specification. Whether you're building a precision rifle for PRS / ELR competition, refining an AR-15 for service-rifle or duty use, maintaining an HK G3 / MP5 institutional platform, upgrading a pistol with a match-grade or threaded barrel, or restoring a classic firearm, you'll find barrel and bolt components engineered for your specific platform.
