The Berger 130 Grain AR Hybrid OTM Rifle Bullet was designed for both reliable and optimal performance in a magazine fed gas gun or an AR style rifle. No other Rifle Bullet compares to the AR Hybrid when it comes to performance out of this platform, and all it will take is trying it once for you to see the difference. Luckily for bolt gun shooters, this round performs just as great even when single fed, as it's Rifle Bullet is made to function well out of all 6.5 Creedmoor chambers.
