[M4 poor workmanship]

Shekkie - thanks for taking the time to post a photo.  Mine looks a bit more pronounced, but glad to hear your 'step' (a better description) hasn't caused an issue.   Maybe it's supposed to be there (?) . . . will be interested to see if others are seeing the 'step' on their M4's.     

Thanks again . . . 

[M4 poor workmanship]

I'm new M4's and hoping to find some perspective.  Thanks in Advance. 

I just received my new Benelli M4, H20 ($2,300)- transferred from another dealer.  Having read this thread before receiving the gun, I examined inside the receiver. 

Looking through the ejection port I noticed poor machining which left a burr large enough to catch a finger nail.  I'm concerned that it might catch the lip of a shell . . . but not sure.   

Question:   Do the M4 experts here think this looks typical / acceptable . . . or like an issue / something that needs to be addressed? 

Does anyone else have a similar burr along that edge?

Thanks again for any perspective.
