[M4 Barrel assembly question]

I took my M4 to the range and it worked fine.  Really fun to shoot.  Apparently the lack of a "click" per the instructions is not an issue.  Thanks to all who replied.

[M4 Barrel assembly question]

Assembling my brand new Benelli M4, following the instructions in the Owner's Manual.  Step 7:

"With the barrel extension resting on the bolt head, and the bolt head fitting into the recess formed into the barrel extension, slip the barrel into receiver. A metallic click will indicate the barrel is correctly seated"

I don't hear any clicking sound, but the barrel is flush with the receiver (see pic).  I can pull the barrel away again with a moderate tug.  Does this sound/look correct?  It seems the fore-end fastening cap is what really keeps the barrel tight to the receiver.

The bolt cycles fine, everything appears to be in order, I'm just concerned because I do not hear a metallic "click" per the instructions.

Hope it's right cause I can't wait to shoot this baby.
