Description

So you’ve milled out and drilled the holes in your LR-308 lower. By now, you’ve done your research, and you’ve learned there’s a difference between Colt’s AR-10 and everybody else’s LR-308. You’ve also learned that unfortunately most all the .308 parts on the market are titled AR-10, and you wanna save the hassle of trying to figure out which parts you need to make it work. Look no further.

We’ve thrown together this kit to help you take the guess work out of matching parts to your LR-308 lower. We’ve given you a correct fitting lower parts kit and a stock and buffer tube assembly fitted for the LR-308 platform. Happy building.

Quality and Performance, Priced Right

The quality control on this LPK’s internals is second to none. Inside you’ll find a disconnector, hammer hook, and sear that were cut and polished to break as clean as glass at 4.5 pounds. The trigger affords 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.

    take down pins

    The forward take down pin was drilled to deep for the detent pin. once the take down pin was in position it would not release without breaking the detent pin. Luckily I had some extended length pins.Had to break to remove.
