Hi Im trying to find some 7075 T6 steel to mill a lower from. I have searched google and I can't find anything. Does anyone know where to find a block of aluminum and what size it would need to be?
Thanks |

T6*
I think you'll find that most of those heat treats will be T651, T65x and so on. You'll probably spend more than with a 80% unless you already own the mills and a way to machine the buffer tube thd. Mcmaster |

| McMaster Carr has 7075 aluminum. You need 1 1/2 thick x 4 inch x 8 inch long. They sell it in 1 foot minimum. I would buy some 6061 first to do prototype before using 7075. It is a lot cheaper, and you WILL make some changes. If you plan on doing a bunch of them, you will want to buy it in 12 foot lengths. I just purchased 96 feet and it was $3.54 a pound. 1 foot is 7.27 lbs. McMaster gets about 50 bucks a foot for 6061 and around 110 bucks for a foot of 7075. You really get ripped when you but small cut pieces. Craig |

Also speedymetals, metalsales, several others |

Just about every town or city has a some form of metals outlet, be it a metals supplier or metals recycle yard. McMaster is a horrible place to go if you are seeking good prices. Use Google, or your local yellow pages phone book to see if you have a metals supplier in or around your location.
A block of 6061-T6 Aluminum 1.5" x 4.0" x 8.0" shouldn't cost you more than $21.00 |
