Gunsmithing Fluting Push Feed M70 Question.

[tstevens]

When helical fluting a Model 70 push feed bolt is there any concern about steering clear of the 2 gas ports on the bottom side of the bolt, midway along the bolt? I would think it would take some serious tinkering with the program and set up to either split the two with a flute or centerpunch them both to put them in the bottom of a flute. Thanks fellas!

I would break out the trusty magic marker to see where you are in relation to the vent holes.

I typically pay no attention to them and just deburr the holes where the flutes runs through them.
I am more concerned with not hitting the ejector spring.
