First, buy a premium grade barrel.
2nd, reinforce the flimsy stamped receiver or obtain one that is milled.
3rd, reinforce the barrel block where it attaches to the receiver.
4rh, tune the gas system
5th, trigger work, get a real two stage for it.
6th, ammunition; start the loading press up and know that you'll be loading these with 308 bullets and not the OEM bore dimensions. You want this because bullet selection is so much better. Understand also that the cartridge is not known as a tack driver to begin with.

Hey, good ideal, while we are at it we can put dicent sights on it and rename it. MAYBE CALL IT AN M14.
