Cerro Forging .308 drawing?


Recommended Posts

My first post! I’m guessing this would be the right place to ask

I have a Cerro Forge AR10 or LR308 ( curved back) solid (0%).  Does anyone know where I can find correct drawings to work on it?  I’ve looked online and it seems like every drawing has different dimensions. I’m guessing it is the LR308 with dpms format, but how can I tell?  I’d love to find the correct print or drawing.  I do have a jig, but it’s no where near ready to even fit in it yet.

 

photo for reference.  Mine has the radius, not the able as in this photo.

thank you

Mike

Are you sured that's a curved back, and not a slant (was it designed to be DPMS specifically)?

I have not seen anyone post here about attempting to finish a forging. This should be interesting. You may have options.

Certainly curious how your mag well turns out when you get to that point.

I see the AmmoLand tag on the posted photo now.

There are some basic blueprints posted around here. But even those that have been published, are all different. Some in small ways; and others in ways that could cause incompatibilities.

Might help to see vaguely what you actually have in this case...

The forging number looks to be 98209 – one. Please ignore all the red markings.  The last photo is my set up where I have drilled the two upper mounting holes, machined the top flat, and the buffer face perpendicular

THis thread needs moved into the 80% section - this isn't the place for it.  The very design of this section is for need to know information, not questions, and it's subsection title is clear.  The whole section was started as Read-Only, but opened up to the public. 

This thread needs moved to 80%.
