+1 for the MKMachining T-Post mounts. Work great and pretty reasonably priced if you buy a bulk pack which it sounds like you would need to reading your plans. I bought the 10 pack earlier this year and no issues. He also offers a SH discount code. Don’t remember it offhand, but use the search function and I’m sure you’ll find it.Mkmachining! Have many of his and there awesome. There t post mount works good and fitting a 63% ipsc in a flat rate box for shipping is awesome. I can gladly live without the 3% to pay a fraction of the shipping. 70lbs in one box for $15 is great.
Looks like I’m gonna be the hype man today. I can also 2nd this. This is a great deal, and I’ve placed two orders with this guy. At extended ranges I’m sure this 1/4” steel would work great. I’m using mine for pistol training which is where 1/4” is really meant to be used.There's a hide member with a thread selling 12" squares/Diamond in 1/4" AR500. You won't find a better price.

Agreed, I was about to post the exact same thing.ar500armor.com is another option. Shitty steel "armor" but decent targets. If you look out for sales you can get some good prices. I picked up an AR500 66% IPSC (1/2") for something like $67 + shipping a while back.
