Balanced Build Foundation

The Vampire V5 delivers solid performance across the board without premium pricing. The 4150 CrMoV nitride barrel offers durability and accuracy suitable for general purpose shooting and training. The 1:7 twist handles a wide range of 5.56 NATO ammunition, from lighter target loads to heavier tactical rounds. Nitride finishing protects the barrel while keeping maintenance straightforward.

USA-Made Bolt Carrier Group

This upper includes a complete bolt carrier group manufactured in the USA from 9310 alloy steel with nitride finish. The 9310 material is standard in quality military and civilian builds, offering reliability without exotic materials. The nitride coating provides corrosion resistance and extended service life. No additional BCG purchase is required.

M-Lok Ecosystem Compatibility

The 15-inch M-Lok handguard gives you mounting flexibility for lights, grips, and other tactical accessories. M-Lok has become the standard in modern AR builds, making it easy to customize your setup over time. The 6061-T6 aluminum construction keeps the upper lightweight while maintaining rigidity.
