LBE Unlimited AR-15 Bolt Catch Plunger 20-Pack Black Steel ARBCPL20PK

The LBE Unlimited ARBCPL20PK delivers precision-machined bolt catch plungers engineered for reliable AR-15 operation and maintenance. This 20-pack provides armorers and serious shooters with essential replacement components manufactured to military specifications for consistent bolt hold-open function.

What Makes This Different

These bolt catch plungers feature heat-treated black steel construction that exceeds standard commercial tolerances. Unlike basic replacement parts, each plunger undergoes precision machining to ensure proper spring tension and smooth operation. The military-grade steel composition resists wear and maintains dimensional stability through thousands of cycling operations.

Key Features

• Heat-treated black steel construction for maximum durability
• Precision-machined to military specifications for consistent performance
• Compatible with all standard AR-15 lower receivers and variants
• 20-piece bulk pack ideal for armorers and high-volume users
• Proper spring tension maintains reliable bolt hold-open function
• Corrosion-resistant black finish prevents rust and oxidation
• Drop-in replacement requires no modification or fitting

Field testing demonstrates consistent bolt catch engagement across various ammunition weights and firing schedules. The precision tolerances ensure proper interaction with the bolt catch lever and magazine follower during rapid fire sequences. These components maintain functionality in adverse conditions including dust, moisture, and temperature extremes common in tactical environments.
