On an AR10 or 308 AR, just remove the ejector and dome the tip that contacts the brass using the drill and file method.
The ejector is held in place and the height is set by the pin holding it in place, cutting the spring will not change the amount it protrudes.

Interesting. I’ve been having jamming issues also on a AR-10 with significant markings on the spent casing. Pulled out the bolt, and the ejector pin is actually protrudes past the bolt face by a millimeter, unlike it being flush in the picture above? Just wondering if I should use the dremel method to shave it down so it’s flush, or take the bolt apart, and shorten the spring?

Hi.

THANK YOU. And for those who don’t want to take it out, I used a patch of gorilla tape with a small hole for the pin. Bumping it on accident won’t marr the bolt head. The second format- a single smoothed chamfer – allows for a bigger chamfer overall. EG, can take 1/2 the pin face. Also, the dremel bit shown isn’t the smallest sanding pad you can use. Easier than I thought it would be.

Just what I need, grinding dust in my ejector channel, extractor pocket, and firing pin channel.

Take the bolt apart to do this and clean it while you’re at it.Good time to lightly stone the edges of the extractor pocket to get the “sharpies” off too.
A thin, pointed stone is needed for the ejector pocket.

Excellent post! This fixed the problem with a 6br we having issues with as well as 6 grendel wildcat. The dremel fix works well. Yes I took it out to do but have used scared bolt faces in AR`s without issue as well.

Thank you very much. I had this exact problem about every 3rd round on a 6.8 SPC. It did fix the problem.

I am really grateful for this post!

Why show the hack dremel tool method? What you did not tell readers is that one nick on the bolt face and it is junk. You should have shown one of the many bolt fixture tools that help to remove the ejector pin. Anyone that owns an AR should own an ejector pin removal fixture to properly disasemble the bolt for cleaning.
