Unusual wear on Dlask 10/22 receiver near extractor - is this normal?

[u/Hot_Cheesecake_905]

Hi all,

I am testing out a new Dlask 10/22 build and have put about 500 rounds through it over the last few weeks. I have noticed the area around the extractor has some unusual wear.

For some reason, Dlask receivers have a channel to the side of the extractor, and the wall between the barrel and this channel is slightly deformed. My extractor is properly timed, and there does not seem to be enough force from the extractor to damage the receiver like this anyway.

I suspect a stovepipe might have been caught in this area, and perhaps the bolt slamming against it caused the wear? Or could be from feed issues - my H3CR magazines have fed rounds in at an odd angle. Or perhaps my TandemKross Spartan Charging Handle?

I also noticed my other target Dlask rifle has some wear in this area, too, but not as noticable since that rifle has a much lower round count.

The gun still functions and shoots fine.

Has anyone else with a Dlask receiver noticed this wear? Is it a known issue, or just normal wear and tear?

Thanks in advance for the help.

I got a response back from DLASK, so it's all good:

Totally normal. It is almost impossible to machine that rib out so we just leave it to wear. It will not in any way be detrimental to the receiver just looks funky. Cast receivers don’t have this because they cast the part without it.
