Description

Please note: We strive to provide the most accurate photographs of our product wherever possible. Due to availability limitations and supply chain constraints, slight variations of the handguard of this upper assembly may occur in the aesthetics of the skeletonizations in between the M-LOK sections.

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 assembly that starts with a 16-inch parkerized heavy-profile barrel paired with a 15-inch free-floating handguard. 

What’s Included

This is not a firearm. It includes an assembled upper receiver, bolt carrier group, and charging handle.

  1. Richard Martin –

    Nice hardware,

    US

    This lower fit like a glove on my Anderson lower! Tolerances are tight, I really like the full length flat top, which gives you many areas to mount your toys. Will take it to the range this weekend and give and update.
