Anthony I don't believe you will get the gun and barrel timed right by trying to use a Clark/Para ramped barrel in a frame cut for the Wilson/Nowlin ramp.Anthony Lombardo said:The feedramp dimensions are the same with the c/p and nowlin ramp so the AET barrels feed great. They have a curved feedramp and actually feed better than a straight ramp so, get a c/p ramp and it will work just fine,
The difference between a c/p and nowlin ramp are in the area that contacts the frame bed. the c/p is radiused and stronger, IMO.
I have in the past milled the radius on a Clark ramped barrel to work in a Wilson/Nowlin frame.
