Seekins Precision
A quality barrel swap is one of the smartest upgrades for a Havak Ph3 rifle owner—and the Seekins Precision 10160135F is engineered to maximize the platform's potential in 300 Winchester Magnum. This 22-inch stainless steel barrel drops into your existing Ph3 receiver, giving you a fresh start for precision hunting or range work without the cost and hassle of a complete new rifle. Seekins Precision barrels are known for tight tolerances and solid accuracy, and in 300 WM caliber you're looking at serious downrange capability for elk, moose, or long-range targets.
The stainless finish resists corrosion in field conditions and wet storage, a practical choice if your hunting grounds see rain or snow. A 22-inch barrel in magnum caliber strikes a reasonable balance: shorter and lighter than heavy match barrels, but long enough to let the cartridge perform without excessive muzzle blast. If you already own a Havak Ph3 and want to switch calibers, add a second barrel to your locker, or simply refresh a worn-out tube, this is a bolt-on solution.
Installation requires basic gunsmith work or a trip to your local smith if you're not set up for barrel jobs yourself. Make sure your Ph3 action is compatible before ordering—Seekins barrels are built to Seekins specs. Once threaded and headspaced correctly, you'll have a new lease on your rifle's accuracy and reliability.
| Caliber | 300 Winchester Magnum |
| Barrel Length | 22 inches |
| Material | Stainless Steel |
| Manufacturer | Seekins Precision |
| Model Compatibility | Havak Ph3 |
| Part Number | 10160135F |
Yes, this barrel is designed for the Havak Ph3 platform. However, barrel installation and headspacing require professional gunsmith work or technical knowledge—do not attempt to install a barrel yourself unless you have the proper tools and experience.
Stainless steel offers superior corrosion resistance, making it ideal for hunters in wet or humid climates or for rifles stored long-term. It requires less frequent maintenance than traditional blued finishes.
The 300 WM is a proven magnum cartridge suitable for medium to large game at extended range, and it is popular in both hunting and precision rifle competition. Actual velocity and accuracy depend on your ammunition, optics, and shooting technique.
The barrel is sold as a bare tube; any muzzle devices must be sourced separately and installed by a qualified gunsmith.
