Key Features
- 62-Grain Light Armor Piercing Projectile: The “green tip” projectile is designed to offer enhanced penetration against intermediate barriers compared to standard lead-core FMJ rounds, making it a functional training analog for specific duty loads.
- Full NATO-Specification: Manufactured to 5.56x45mm NATO (M855) standards, this ammunition generates the pressure and performance intended for reliable function and consistent ballistic results in chamberings designed for this specification.
- Reliable Brass Casing & Boxer Primer: The brass casing ensures smooth feeding and extraction, while the Boxer primer is non-corrosive and facilitates easy reloading for handloaders who process their own brass.
- High-Performance Ballistics: With a muzzle velocity of 3100 feet per second and 1323 ft-lbs of muzzle energy, this load delivers a flat trajectory and consistent downrange energy transfer for training at extended distances.
- PMC X-Tac Consistency: PMC’s X-Tac line is known for its military-inspired quality control, providing lot-to-lot consistency in velocity and pressure that shooters can trust for repeatable performance.
- 20-Round Convenience: Packaged in a standard 20-round box, it offers a practical quantity for range sessions, training drills, or secure storage.
Performance & Applications
This ammunition is purpose-built for specific, demanding scenarios. Its design supports several key applications where its performance characteristics are most advantageous.
Advanced Tactical Training: For individuals and agencies conducting barrier penetration or vehicle-based training, the light armor-piercing projectile provides a more realistic training effect compared to standard range ammo, allowing for safe, proper training on target engagement through various materials.
Long-Range Target Practice: The 62-grain projectile’s higher sectional density and sustained velocity, compared to lighter 55-grain loads, can improve performance in windy conditions and at distances beyond 200 yards. This makes it an excellent choice for shooters looking to practice marksmanship fundamentals at extended ranges with their 5.56 NATO rifle.
Duty Rifle Qualification & Familiarization: Shooters who maintain a duty-ready or defensive rifle chambered in 5.56 NATO can use this ammunition to practice with a round that closely mirrors the ballistic profile and recoil impulse of typical duty ammunition, ensuring their training translates directly to their intended use case.

Bought this as part of a larger build project. Bordertownguns had the best price by a decent margin and shipping was fast. The PMC Ammunition X-Tac Brass 556 Ammo 62-Grain 20-Rounds Li… itself is well-made — Good lockup. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.

Been in the market for a while and finally decided to buy from Bordertownguns. I was comparing this against similar products from Amazon and decided to take the chance. Glad I did. Arrived in 2 days, well-packaged, and the quality speaks for itself. Installed it on my Glock 43X and ran 494 rounds through it without a single hiccup. This is the real deal.
