We started with a non-padded sling called the MK-1. If you are wondering where that name came from, “MK-1” was the Naval nomenclature that Mike Noell at BLACKHAWK! came up with due to his background as a SEAL, and we just stuck with that. We now offer an MK-2, which is the padded version. If you’re carrying a heavier rifle for sniper use, it helps with the weight, especially for guys that aren’t wearing body armor, because a lot of body armor has big shoulder pads.
We then made a lightweight multi-cam sling, and I told my former cohorts that we had made it for them, just as a joke. A couple of weeks later they ordered a bunch of them. That was when we decided that we had to make that sling.
Since then, we have made the slings out of different materials to make them lighter. We have added rubberized pull tabs, some with bungee that can transition from a two-point to a single-point. I prefer the bungee sling if I am using something like an MP5 or MPX, because the gun is more compact, and the sling typically attaches at the rear of the receiver. The only thing I don’t like about a bungee sling is if I use it on my M4 or AR-15, I have a harder time getting it really tight to allow me to shoot more accurately. So, if you’re going to do a lot of dynamic stuff, I’d say it’s fine. But if you’re focusing more on 100- to 300-yard shooting, then you probably want to use one that doesn’t have a bungee.
