AR-15 lower specs

does anyone know where i can find the dimensions and specs of what a lower receiver should be made to? Not that im equiped to make any but rather id like to measure my own ( measurin for fun, ima build it either way ) Things such as my trigger/hammer pins should be .154 +/- .005" and so on. I tried googling it but to no avail:rolleyes:

I think ARFCOM has schematics, but they are hard to read if IIRC.

I have found this site to useful in sizing pins and springs.

Thanks Dave, but your right, they are kinda hard to read, and drrufo, thats exactly what i needed! Its got like all the spec.s on the receiver, and even those SCARY DIAS's the brady's have nightmares over :-) thanks guys
