Anyone here know the size of the gas port on the $275 DSA uppers? I just picked one up and it hits pretty hard. I am used to shooting Colt and Noveske 14.5" carbines so I felt a sharp recoil pulse. I did have a carbine spring and bufferfrom AIM surplus.
I’d be surprised if they’re consistent sizes. Good luck.
Contact them directly - they usually have spec sheets and someone can probably dig that up if the CSR doesn’t know.
Ask for Shari if you can, she’s great!
