LR-308 Classic Lower Build Kit | Lower Parts Kit | Stock & Buffer Tube Assembly

“AR-10 or LR-308?  I want to build one, but don’t know which I have or the parts I need.”  This might be the most common issue there is when it comes to building one’s own .308 calibered AR-style rifle.  Well, relax.  We’ve taken away the guesswork, the need for questions, the whole cloud of confusion.
We put together a kit with all the right matching parts.  You come up with whatever LR-308 lower you intend to use in your build and pair it with this kit.  When you’re done assembling it all, you’ll be at the halfway point in your entire build.
Perfectly Polished for Performance
The quality control is outstanding and the finish shows it: Inside you’ll find a disconnector, hammer hook, and sear whose interacting surfaces were laser-cut and polished to break as clean as glass at exactly 4.5 pounds. With the trigger, you’ll experience a perfect reset after every pull, with no break-in required. Every roll pin presses easily, while the hammer and trigger pins glide in with little effort.
