If you're a hunter, you can appreciate the need for a somewhat larger caliber at a more intermediate range. You'll need a rifle whose ability really shines in this area. And what better way to avoid paying current market prices than to build it yourself? So check out this LR-308 build kit.
You get a pre-built upper side-charging assembly that starts with a 16-inch parkerized heavy-profile barrel paired with a 15-inch free-floating handguard.
What’s Included
