WEBSITE EXCLUSIVE — Limited Edition Faxon Match Series Gunner Profile 7.5" 1:5T Pistol Gas 300 BLK AR-15 Barrel — Stainless Steel PVD (15B35P7NGQ-5R-NP3-SSPVD)

The Faxon Match Series 7.5" 300 BLK Gunner Profile barrel — now offered in a website-exclusive, limited-edition Stainless Steel PVD finish — is built for the most common real-world 300 Blackout use case: a compact AR pistol / PDW setup running heavy subsonic ammo, often suppressed, where bullet stability and consistent cycling matter more than anything else. A fast 1:5 twist (RH) helps stabilize longer, heavier 300 BLK projectiles in short barrels, and Faxon’s Match Series architecture is designed to keep performance repeatable: 416R stainless steel with 5R button rifling to help reduce jacket deformation and fouling versus traditional sharp-shouldered rifling. If you’re building a short 300 BLK that needs to run subs (and still behave when you switch to supers) — and want a refined, premium aesthetic to match — this SKU is engineered to remove uncertainty.

Every Faxon rifle barrel begins life inside our Greater Cincinnati manufacturing operation, where we control critical steps from raw steel to finished barrel. Blanks are cut, drilled, reamed, and rifled in-house, then stabilized via stress relief before final profiling. All Faxon barrels are 100% magnetic particle inspected (MPI), and this limited-edition variant is finished with a high-end Stainless Steel PVD (Physical Vapor Deposition) coating — bonded at a molecular level to the underlying stainless for excellent corrosion resistance, wear protection, and a distinct, refined visual character that sets it apart from the standard nitride-finished Match Series barrel. For this specific barrel, critical features are verified using air-gauge bore checks, custom hardened gauges, coordinate measuring machine (CMM) verification of chamber geometry, along with 300 BLK GO/NO-GO headspace verification.

Suppressor ecosystem tip: If you plan to shoot both subsonic and supersonic loads—especially suppressed—pair this barrel with a tunable gas solution. An adjustable gas block and appropriate buffer/spring tuning can reduce blowback, smooth recoil impulse, and improve reliability across ammo types.

FAQs

What is the SS PVD finish, and how does it compare to QPQ nitride? ▾

PVD (Physical Vapor Deposition) is a vacuum-applied coating that bonds at a molecular level to the underlying 416R stainless steel. Compared to QPQ nitride — which is a salt-bath surface conversion that hardens the steel itself — PVD produces a more refined, premium visual finish while still delivering strong corrosion and wear resistance. This SKU is offered as a website-exclusive limited edition for builders who want a more distinctive aesthetic on their 300 BLK pistol build.

How is this different from the standard Match Series 7.5" 300 BLK Gunner? ▾

Mechanically and dimensionally identical. Same 416R stainless, same 5R button rifling, same 1:5 twist, same chamber, same gas port, same Match Series inspection process. The only difference is the exterior finish — Stainless Steel PVD instead of Salt Bath Nitride / QPQ — making this a premium aesthetic variant of a proven barrel.

Is this barrel made in the USA? ▾

Yes. This barrel is manufactured in-house by Faxon Firearms in Greater Cincinnati, Ohio.

Who is this 7.5" 300 BLK barrel for (and not for)? ▾

Best for: compact AR pistols/PDWs, suppressed setups, and heavy-for-caliber subsonic loads where stability and tunability matter most.

Not ideal for: prolonged rapid-fire strings where maximum heat tolerance is the primary goal (consider Combat or Duty options depending on priorities).

Why a 1:5 twist for a short 300 Blackout barrel? ▾

Short 300 BLK builds are commonly paired with longer/heavier bullets, especially for suppressed subsonic use. A fast 1:5 twist is selected to support stabilization and consistency with those projectiles in compact configurations.

What do I need to know for compatibility (threads, gas, gas block size)? ▾

This barrel uses 5/8x24 muzzle threads, an AR-15 pistol-length gas system, and a .750" gas block journal for standard .750 gas blocks (including adjustable gas blocks).

How is quality verified on this barrel? ▾

Faxon verifies critical features through inspection gates including air-gauge bore checks, custom hardened gauging, coordinate measuring machine (CMM) verification of chamber geometry, 300 BLK GO/NO-GO headspace verification, and 100% magnetic particle inspection (MPI).

Is this a good barrel for suppressed shooting? ▾

Yes—this barrel is purpose-aligned to suppressed 300 BLK builds (especially heavy subs). For best results across subs and supers, use a tunable gas solution and buffer/spring tuning matched to your suppressor and ammo.
