Although our barrels are not chrome lined, the expected service life is about 15,000 rounds. Because of how chrome-lining is applied, the barrel must be over-bored, this can have an adverse effect on accuracy. At HD Defense, when we offer a precision product, we expect it to perform as such. The truth is, most modern pistols and rifle barrels are not chrome lined, and realistically, you would have to spend over $5,500 in quality ammunition before you have to start concerning yourself with reaching the end of our barrel’s service life.
Chrome lining is usually recommended when there is a high probability of using corrosive ammunition. Being that we have not run into any corrosive 5.56 or .223 ammo manufactured in the last 20 years, and we think it’s a safe bet that you won’t either (unless of course you happen to come across some antique Vietnam era ammunition, which we recommend you avoid). In some of our higher end builds we do offer melonited barrels, however at this time they are special order items. We expect to start stocking them as we continue to grow.
