This bag is perfect for the Tavor 16 with RDS mounted...looks like it was designed for that rifle (and I've been searching a decently priced bag that can be locked, so 5.11 solution is perfect!!) The single shoulder strap is not bad, has nice cool mesh against the body.
Initially I was disappointed that front pocket has no pocket or divider for mags etc, but quickly learned (after reading description on website) that the front pocket is for the bail out bag. I have a low profile chest rig or a bandoleer now. Perhaps Velcro loop might be a nice addition for future upgrade, just so some folks can customize inside.
So why 4 stars...let me just say the bag is, eh, ugly. Black and khaki is not something you'd see on the street. So for the "CCW" purpose, you'd be standing out as the dude carrying an ugly bag, lol. (I'm using the bag as a rifle carrier to the range)
