briarbeavis01 Posted February 16, 2015 Share Posted February 16, 2015 The top of the ejection port towards the rear of the port looks and feels rough like the shell casing is hitting the top of the port when the hulls are ejected. Is this a problem at all? Just feels kinda like a serrated edge but does not effect function of the firearm. Any ideas? Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted February 16, 2015 Share Posted February 16, 2015 Normal. Every m4 does this. It's self limiting. On my 12k+ m4, it's almost polished smooth and beveled. Quote Link to comment Share on other sites More sharing options...

This is literally the same as the little teats wearing off of your vehicles new tires, regarding importance/"level of issue". Quote Link to comment Share on other sites More sharing options...
