The Sling Doober™ is the long-awaited sling storage system for the rear of your rifle. Here at Tremis Dynamics, we have long said that the best storage method was masking tape. And that is the easiest method for stowage. However, for folks that train, they will run dozens of reps per training day where they will deploy that sling, requiring a lot of retaping. Ranger bands and the like are a great way to get shit caught up in your charging handle so we don't recommend them. (At all, ever)
The Dev Team has been trying different methods for about two years, trying to find a solution. Commercial products or custom, we tried a lot of methods. Finally, we landed on this plan. A sling hanger, attached with a user-replaceable shock cord to a custom-sewn doober-tab.
The hanger is wrapped on the sling at the apex of the slack when it's wrapped around the back of the stock. The hook can be attached to a number of locations, but we usually attach it to the same point the end of the sling is attached to.
The MOD 2
The Mod 2 was something we started testing shortly after we started testing the original Doober (Now affectionately known as the Mod1). The principle is identical, but the materials are different. We omitted the larger Steel HK hook for a lower profile Stainless Steel Maratac hook. There is less bulk which is a plus, but there is an extra point of articulation. Some of the Dev Team thought this made stowing it a smidgen slower. It does not affect deploying it.
One area where the MOD2 shines is for lefties. Underhooking the doober is the ideal method for stowing it and the MOD1 works great on the right side of the gun but needs to be twisted for the left. The MOD2 can simply be disassembled, flipped, and reassembled by the end-user. The hooks are more expensive, but the doober tab is easier to sew so the final cost is the same.
The MOD 3
We omitted the custom polymer hanger and are using Onewrap™ which offers some distinct advantages. The sling does not need to be disassembled to attach, remove, or relocate the doober. It fits a wider selection of slings. All the way from 1" wide economy slings to 2" wide padded slings. Just cut off any excess material after you fit it to your sling. It is also quieter as there is less plastic hardware to be bouncing around when the sling has slack in it. And all the hooks are now black instead of raw stainless like the MOD2. The Doober Tab has been sewn slightly differently to offer a normal pull tab on one side and a shortened pull tab on the other to make it easier to grip.
