DS Arms upper gas port diameter

[Kiznelly]

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 buffer (http://www.aimsurplus.com/product.aspx?item=XDSABK&groupid=53)from 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!
