The interior grooves and contours will affect the bullet as it leaves the gun, resulting in less or more velocity. The bullet is impacted by more pressure along the length of the barrel, picking up more speed, and resulting in a higher muzzle velocity.īarrel shape and design will also impact velocity. Longer barrels usually mean more velocity. Here are some of the main ones: Barrel LengthĪs mentioned above, barrel length impacts the velocity of a bullet. Simply put, many factors impact the velocity of a bullet. What Factors Impact the Velocity of a Bullet? Of course, this also heavily depends on the shooter’s skill, and can also be impacted by the twist rate of the barrel. Higher velocity tends to lead to more accuracy because the bullet can travel in a straight line more efficiently. This is because the bullet is impacted by more pressure traveling the length of the barrel, and will leave the gun with more velocity. Typically, longer barrels mean higher velocity.
Yes, barrel length matters and will make a noticeable impact on your AR-15’s performance.įirstly, barrel length impacts a bullet’s velocity. Does Barrel Length Matter When Shooting an AR-15? Mark the rod, and measure the distance from the mark to the end. If you still can’t find it, take your unloaded AR-15, and stick a rod down the barrel as far as it can go.
