Just got these in...I had been searching for a quality pillar material to use on my rifle build...searched high and low...didnt want to use lamp rod as I am sending the stock out to Jeff at CDI to be inlet'd for DBM so I wanted aluminum to ease the load on his tooling, brass or bronze is lots harder than aluminum...last week I stumbled onto ERNIETHEGUNSMITH.COM I bought enough 1/2" OD x .252" ID x 4" and 3/8" OD x .252" ID x 4" rod stock to do 5-6 rifles for $19.85 shipped...pillar stock came today and it is QUALITY material...great tutorials on his website too...
