So I bought a Odin Works Aluminum Gas block from opticsplanet accidentally. ( i didn't pay attention and realize it was aluminum until after I ordered it. )... Being as its a small/cheap $20 part, I'm not going through the hassle of starting a RMA. Since rules say all posts must have a price, Asking $20 obo. but really, the first 12 pack of Budlight or PBR gets it. Located in Gonzales near Hwy 44/Germany Rd. I'll be home all weekend. Its literally brand new. Came in the mail today. I haven't even slid it onto a barrel.
