Can you chrome line a barrel?

Chrome-lining protects the barrel from corrosion, but this is not the main purpose for lining a barrel. Chrome-lined barrels are also easier to clean, but the military would not invest in a chrome-lined barrel just to save a grunt some time swabbing out the bore. That heat is what can quickly ruin a barrel.

Are chrome lined barrels good?

While chrome lining offers superior corrosion resistance to various external weather conditions, it also serves to significantly reduce throat erosion, allowing shooters to enjoy sub-MOA accuracy potential for as much as 20,000 rounds of normal use with factory match ammunition.

Are HK barrels chrome lined?

HK engineers choose to not chrome line the barrel because they believed it could mask imperfections that could reduce accuracy. This means that the internal diameter of the barrel at the muzzle is slightly smaller than the diameter at the chamber end.

How long does a chrome lined barrel last?

308 AR (chambered in M118LR): Shooters using these rifles typically experience serviceable barrel lives in the neighborhood of 5,000 – 8,000 rounds with an untreated bore. Chrome lined or nitrided barrels will last considerably longer before requiring replacement.

Can you Nitride a chrome lined barrel?

Stainless steel can be easily nitrided, but it is very difficult to add chrome to stainless steel. Nitride significantly increases the barrel life and corrosion resistance of “stainless” (which for barrel stainless steel is not rust-proof).

How long do chrome lined barrels last?

What is the lifespan of an AR 15 barrel?

The average life of an AR-15 barrel is about 20,000 rounds. Let’s generously assume that the average new shooter goes to the range once a month and fires 100 rounds through their rifle per session. At that pace, it would take about 16 years to wear out that barrel.

Is a phosphate barrel good?

Yes. Most barrels with phosphate coated exteriors have chrome-lined interiors. This is more durable during extreme full auto firing. If your use case is regular semi-auto fire, a nitride coated barrel vs a phosphate coated/chrome lined barrel is pretty much a wash in terms of durability.

Which is better phosphate or nitride barrel?

A nitride exterior will protect the barrel longer than a phosphate exterior finish. However, a chrome-lined, or phosphate, barrel will hold up better to sustained fire than a nitride interior. Nitride has a slight edge in accuracy and price. However, phosphate coated/chrome lined barrels are more common.
