I've got a Talley 20MOA inbound.
From what I found, they're the cheapest 7075 aluminum rail on the market. I don't know much about if there's any difference,a long as you buy good metal from a reputable manufacturer,and I am sure Talley is. I discussed this with Gundoc about 6061 VS 7075 VS Steel. Like most thing it seems like for me, I went with a middle of the road route, thought 6061 might be a bit soft and steel as overkill on a 6.5Creedmoor. I did some reading after we talked. To put in in perspective 6061-T6 which is commonly used in the gun industry has a minimum yield strength of at least 35, 000 PSI. 7075-T6 is at least 63,000 PSI. 6061-0 which is annealed has a minimum yield of 8,000 PSI which is still plenty for a scope base/rail. Interesting how much the strength varies in the two alloys of 6061 with T6 having 4X the stength.
