Spikes Tactical 14.5" Mid-Length Lightweight Barrel
Over the course of its life, a rifle can lose its accuracy from heavy use. The loss of accuracy is more likely at long-range distances. A less-accurate rifle may not be a problem if you are shooting at closer ranges, but it can really bite you as you target objects further and further away. You’ll know it’s time to think about a replacement when your bullets begin keyholing and when your groups begin to open up.
If you have a tendency to shoot fast and hot, you will wear out your barrel faster than if you shot slow and cool. Law enforcement officers, military personnel, competitive shooters and others who spend large amounts of time at the range will need a replacement sooner than those who don’t work their AR-15 at such a fast clip.
New barrels are not only used to repair a well-used rifle. You may want a new look for your existing rifle or perhaps you’re building an AR-15. Spike’s Tactical 14.5" mid-length lightweight barrel is chambered for 5.56 NATO / .223 Remington and may be the perfect match for your weapon.
