MCK Extended Barrels Guide (9inch & 16inch) | CAA Gear Up

What extended barrels are available for MCK conversion kits and what are their specifications?

CAA Gear Up offers precision-machined 9-inch and 16-inch extended threaded barrels designed specifically for handguns utilized within the Micro Conversion Kit (MCK) chassis lineup. These drop-in match-grade barrels serve two primary functions: enabling suppressor compatibility on MCK platforms or converting standard handguns into 16-inch rifle-length carbines for enhanced velocity and long-range accuracy.

⚙️ Detailed Breakdown of CAA Gear Up Extended Barrels

1. 9-Inch Threaded Barrels ($179.99)

Designed specifically for shooters operating suppressors with their MCK EVO, Gen 2, or Gen 3 kits:

  • Suppressor Clearance: Extends standard ~4" factory handgun barrels to 9 inches, placing muzzle threads outside the front shroud to prevent baffle impact or heat damage.

  • Threaded Muzzle: Comes factory-threaded with standard pitches (e.g., 1/2x28 for 9mm or .578x28 for .45 ACP).

  • Supported Models: Available for Glock 17 (Gen 3–5), Glock 19/19X/45 (Gen 3–5), Glock 20/21/22, Shadow Systems DR920/MR920, and PSA Dagger.

2. 16-Inch Carbine Threaded Barrels ($245.00)

Converts pistol-caliber handguns into full-length rifle configurations:

  • Increased Muzzle Velocity: Adds significant length over factory handgun barrels, allowing complete propellant burn for higher projectile velocity, flatter trajectory, and extended effective range.

  • Legal Rifle Compliance: Pairing a 16-inch barrel with a shoulder stock configuration satisfies federal 16-inch minimum barrel length requirements for rifle classification.

  • Supported Models: Available for Glock 17, 19, 22, 23, 29, 30, 34, 35, Smith & Wesson M&P 2.0 (4", 4.25", 4.6", 5"), Taurus G3, and Polymer80 940C.

3. Drop-In Installation & Break-In Guidelines

  1. Ensure the handgun is completely unloaded, clear, and field-stripped.

  2. Remove standard factory barrel and recoil spring from the handgun slide assembly.

  3. Drop the CAA extended barrel directly into the slide lock lugs (no gunsmithing required).

  4. Reinstall recoil spring assembly and reassemble the slide onto the handgun frame.

  5. Apply firearms oil to the exposed barrel surface to minimize friction against the chassis shroud during initial cycling.

💡 PRO TIP: Always use a thread protector when firing without a suppressor attached to prevent damaging external muzzle threads against the internal chassis blast shield.
