The Seekins Precision Havak PH3 300 PRC 22″ Urban Shadow is a production-grade precision rifle built for shooters who demand repeatable sub-MOA performance in a lightweight, modular package. Chambered in .300 PRC with a 22-inch fluted, threaded barrel, this bolt-action uses the PH3 three-lug action with a 60-degree throw for rapid cycling and a tool-free quick-change barrel system for field-swapping calibers or replacing a worn tube. The Urban Shadow carbon-composite stock integrates a full-length M-LOK handguard and a 20 MOA Picatinny rail, with a TriggerTech user-adjustable trigger providing a crisp, creep-free break from 1.5 to 4.0 pounds. This is a serious tool for long-range engagement, not a safe queen.

Key Features
- PH3 Three-Lug Action – The 60-degree bolt throw clears low-mounted scopes and enables faster follow-up shots without sacrificing lock time or extraction reliability.
- Quick-Change Barrel System – Tool-free barrel swap allows you to switch between .300 PRC, 6.5 Creedmoor, or .308 Win in under two minutes, extending barrel life and mission flexibility.
- 20 MOA Picatinny Rail – Integrated rail provides 20 MOA of built-in elevation cant, maximizing your scope’s internal adjustment for long-range holds out to 1,500+ meters.
- TriggerTech Adjustable Trigger – User-adjustable from 1.5 to 4.0 pounds with zero creep and a glass-rod break, giving you a consistent pull weight for precision shooting.
- Full-Length M-LOK Handguard – Continuous M-LOK slots at 3, 6, and 9 o’clock allow direct mounting of bipods, NV bridges, and rail sections without extra adapters.
Who It’s For
This rifle is for law enforcement precision marksmen, military snipers, and serious long-range competitors who need a sub-MOA platform that can be rebarreled in the field. It suits shooters who run suppressed—the 22-inch threaded barrel is suppressor-ready with a 5/8×24 pattern. The Urban Shadow colorway reduces signature in low-light urban environments. If you train with a single caliber but deploy with another, the quick-change system eliminates the need for a second rifle.
Pros & Cons
- Pro: Tool-free barrel swap saves time and money on rebarreling; compatible with multiple calibers.
- Pro: Weighs 7.4 lbs bare—light enough for carry, stiff enough for sustained fire.
- Pro: TriggerTech trigger is user-adjustable without disassembly; no gunsmith required.
- Con: The carbon-composite stock has limited LOP adjustment compared to full chassis systems—shooters with very long arms may need an aftermarket spacer.

The Havak PH3 undercuts both competitors on weight and price while offering a quick-change barrel system that neither Zev nor Geissele provides. The ZRX is limited to 6.5 Creedmoor; the Geissele is fixed in .308 Win. For shooters who need .300 PRC ballistics with modularity, the Seekins is the clear choice.
