[Looking for a good tactical sling for my M4. Suggestions?]

The above slings seem to be meant for a standard stock.

Any recommendated sling for a M4 with Skeletonized Stock?

Anyone knows what sling does the USMC uses with theirs?

Thanks...

[New M4]

hi, i am picking up my new M4 from a dealer soon.

 

Need help with some questions:

 

1. What comes with the weapon? User manual, number of choke, any sling etc..

 

2. Is there anyway to identify which year is it made?

 

Thanks....
