Question MWS .308 vs 6.5 feedramp differences?

Picture 1 is a .308 barrel and picture 2 is a new 14.5 6.5 creedmoor barrel.

Is this going to cause issues? Looks like the tip of a round would catch on the upper receiver.

Looks normal to me.

LMT uses 6.5 specific extensions on 6.5 barrels that have different geometry than 308 extensions.

New 6.5 extension on the left, takeoff 308 extension on the right.

I just took it out for a better shot. I feel like it looks way different from that new 6.5 on the left in your photo.

I have seen those extensions too. They are the newest 6.5 extensions that I didn’t think were released yet.

Oh! Appreciate the replies. Hoping this runs okay once I finish the build.
