Product description
Obsidian Arms Enhanced Pin Kit: Hard Chrome 4340 Steel for Maximum Durability
Features
- 4340 alloy steel construction for superior strength
- Heat treated for enhanced durability
- Hard chrome finish on firing pin and cam pin
- Corrosion resistant coating
- Minimal surface friction for smooth cycling
- Nickel plated retainer pin
- Made in USA
The Obsidian Arms Enhanced Pin Kit solves the premature wear problem of standard mil-spec pins by using 4340 alloy steel with hard chrome plating that resists wear and corrosion far better than standard phosphate-coated parts. This kit works exceptionally well for high-volume shooters, suppressed rifles that see increased carbon buildup, and builds where reliability and longevity matter more than cost savings. What sets this Obsidian kit apart is the hard chrome finish that reduces friction and prevents carbon buildup – your bolt cycles smoother and stays cleaner longer, and the 4340 alloy steel construction provides strength that won’t fail even under full-auto fire schedules.
