I recently picked up one of those excellent Adcor billet lowers.

I am ready to build it up and it seems that parts are now becoming more and more available. This will be my 4th AR build.

It seems it is fairly easy to find high quality complete LPKs. However, I now have a growing collection of pistol grips and trigger guards that I will never use. I also want to build this billet lower up as DMR type rifle. Most likely I will use a high quality trigger system of some type, so I will only need all of the other lower parts. Does anyone know of a quality source for all of the other small parts for the lower outside of the trigger, hammer and associated springs?
