What twist rate is best for an AR-15?
Most modern AR-15 barrels will come in three twist rates: 1:9, 1:8, and 1:7. The 1:9 barrel is best for stabilizing lighter and mid-weight bullets between 45 and 77 grains. The 1:8 twist barrel is the most versatile of the bunch, the perfect option for16-inch carbine AR-15 (the most common configuration on the market.)
What is the most accurate barrel twist?
The 1:8 twist barrel is the most versatile of the bunch. This twist rate gives you the most flexibility, effectively stabilizing projectiles up to 80 grains but not over stabilizing lighter ammunition. The 1:9 barrel is best for stabilizing lighter and mid-weight bullets ranging between 45 and 77 grains.

Do higher grain bullet kick more?
An established fact is that at a given PF a heavier bullet going relatively slowly will produce less recoil (and muzzle rise) than a light bullet going faster. Additionally, the lighter bullet will spend less time in the barrel which means a faster recoil impulse and thus a bit more muzzle rise.
What grain means in ammunition?
Essentially, the grain count of a round is a way to measure the size of the bullet. So when the box of 5.56 ammo you just bought says that it’s 62 grain, that means the bullet weighs that much. The actual weight of a grain is extremely small. To weigh an ounce, you’ll need 437.5 grains.
