Thanks appreciate the help

Well the rail says it's 2.06 in height. And I'm worried that if I get a high profile upper receiver from another manufacturer it won't match my lower receiver lol.

Well guys I'm new to the ar-10 world and I have purchased a dpms LR-308 sporticle. Here is my problem the upper receiver that came on the gun, is 1/2 in rail height. No not a 1/8 or 3/16 a 1/2 in so I bought a high profile xts 15 in rail. So now I have to buy a high profile upper receiver. What upper do I need to buy, because I've heard only certain ones work. Thanks , tye
