AR-15 Barrels in stock available at cobratac
Lets take a look at some of the differences and options you need to consider when choosing what barrel to go with for your AR15 rifle.
Stainless Steel – Stainless barrels are heavier , They can also be more accurate because the alloy is more maliable and allows for finer precision during the manufacturing process, if manufacturer takes time to do so.
Chrome Lined vs Non-Chrome Lined – Chrome lined barrels tend to be better at extraction and corrosion resistance and cleaning but tend to be slightly less accurate than standard non-chrome lined barrels, but this difference is so nominal that most users will never notice a difference.
Barrel Twist Rate – The barrel twist rate basically means how many complete revolutions does the rifling make inside the barrel. For example a 1:7 twist rate means that every 7 inches the rifling makes one complete revolution around the inside of the barrel.
Barrel Lengths – There are many options for barrel lengths, 7.5″ – 10.25″ – 11.5″ – 14.5″ – 16″ – 18″ – 20″ and a several others.
Barrel Contours – Your standard barrel contours are Lightweight (pencil) Barrel – M4 Contour (mil-spec) Barrel – and the Heavy Barrel(H-bar) – and many other barrel designs, many of which are custom or fluted designs that each offer their own unique advantage and disadvantages.
