Black Arc Munitions NAS3 (262 Alpha) 5.56 NATO 77gr Sierra MatchKing Ammo - Box of 50

The Blackarc Munitions 262 Alpha Special Edition celebrates the brand's third year of online sales with a black-coated, 40,000-round limited run of their premium match-grade 5.56 load. Built around Blackarc's NAS3 nickel alloy stainless case paired with the 77gr Sierra MatchKing projectile, this 5.56 ammo delivers leading velocity, lower standard deviations, and reduced weight for SPR and short-barreled rifle applications.

Features:

• 77gr Sierra MatchKing (SMK) projectile
• NAS3 nickel alloy stainless case
• Chambered in 5.56x45mm
• Special Edition black coating, limited to 40,000 rounds
• Average velocity: 3,000 fps (20" proof barrel test)
• G7 ballistic coefficient: .190
• Sporting/competition application
• 20 rounds per box

The NAS3 case design and 77gr Sierra MatchKing combination is primarily developed for maximum performance from SPR and short-barreled rifles without the velocity penalty those shorter barrels typically impose, making it a heavy-hitting option for demanding 5.56 SPR and SBR applications. This Special Edition run carries a black coating exclusive to the anniversary release, offered at no additional cost over the standard load as a thank-you to customers who've supported the brand through its first three years online.

Note: this is a high-performance round; some rifles may require mass regulating or tuning of the gas system.

Blackarc Munitions specializes in premium match-grade 5.56 ammunition, applying advanced case design and technology to deliver competition-level performance and consistency.
