My new Remington R15 appears to not have a chrome lined barrel nor chamber, and the inside of the bolt carrier, does not ether, I shot this rifle last weekend, and did not clean it. Got it out again the next day, to shoot it again, and it was jam city, until I cleaned it, after that, it was perfect. It eats hornady factory ammo all day long, but you can forget about steel case Russian crap. It will not feed it, without jamming. It don't matter how clean the rifle is, it appears to only like brass case ammo. Anyone else seen this.
