Hi

I am looking for some barrel drawings for the Bren.

I am making some 7.62 NATO Bren barrels and I need the drawings for the barrel.

I have made test parts and the threads fit the barrel nuts. At least 7 mm square threads thread on the barrel nut.

I am not sure how to time the interrupted thread cut out to the lead of the thread.

I am not sure of the gas port hole size for 7.62 NATO.

Any help would be greatly appreciated.

I make barrel from solid bar.

thanks
