If I do another A2 build, I will use this upper. Of course I’ll have to send it to ADCO for drilling. I have no use for the fwd assist. It just adds unneeded parts. I shoot normal handed as well.
What am I looking at?
I thought that was a shell deflector then realize its over the dust cover
what will you be drilling?
answers man answers!!
It a 9mm upper. You are seeing a gas deflector and modified port door. The gas tube hole is not present and would need to be drilled. Then install a std port door and call it done.
