It's said that after extended use, the .223 Wylde caliber barrel is more susceptible to wear and loss of accuracy. This shouldn't be a cause of concern for the civilian shooter. The truth is, it takes firing thousands and thousands of rounds fired for that to be true.
But if you're still worried about it, let us offer a solution. This AR-15 build kit comes to you with a 16-inch, 416R, steel heavy profile barrel pre-mounted in its upper receiver instead of a standard or M4 profiled one. That means this barrel is extra tough, so you can maintain accuracy with prolonged use. It also means you won't suffer barrel wear, even after thousands and thousands of rounds fired. Oh, and one more thing: it's finished in that lustrous stainless steel, because there's no reason your go-to workhorse can't look good too.
As an added bonus, we included an aggressive-looking 12-inch slanted free-float M-Lok handguard. Mount whatever accessories you want to really make your rifle your own.
