Hello,
Recently bought Huang's MK18 II 7" Rail system as well as a correct Madbull barrel collar for G&P/WE receivers.
However, I can't seem to be able to install it.
First, the rail seems to be about 1/4" too long...
PS : Don't tell me I have to remove the delta ring and all that crap. I know. 'just lazy right now for pictures.
Also, there is 6 holes on the rail systems as well as 6 screws, but only 5 holes on the thingy that sits between the barrel collar and the receiver.
What am I doing wrong here?
