Not hard but get an undrilled barrel. Those combo blocks use 90deg ports and AMD 65 uses a 45deg port.

I've had good success with this one:

45 degree gas port, sight elevation and windage adjustment with a slotted screwdriver, bolts on vs. being pinned (high temp solder/braze is another option, but not necessary) and has a very modern look.

So that one looks like it can b used for either 45 or 90 gas blocks. It also looks like it would use the same gas port hole as the original one, they look interchangeable. thats exactly what im looking for if im right

I wouldn't count on it working with a 90 degree gas port. I had two GM 1970 barrels with 90 degree gas ports I tried to build up into an M70 that had to be welded over and redrilled because the port was too far forward. Your mileage may vary.
