Hey guys, I have a dracos 7mm-08 barrel in my ar10. I have had this thing apart for a while and have moved twice and now when trying to get it back together I cant find the gas block (dwell chamber, or whatever they call it) screws. I was just wondering if somebody had a barrel that they could check the thread pattern and length for me so I could get some replacement screws. Thank you for any help in advance.
