The video opens on the range with a demonstration of an easy transition from strong-side to weak-side using a rifle sling. The discussion focuses on turning a two-point sling into a single-point style setup quickly, and why that can matter in training and practical use. The host from Classic Firearms introduces Paul from Tech10 Tactical, the designer of the sling system being shown. They are working with B5 Systems and LMT SOPMOD-style stocks that lack built-in QD sockets. The host notes that the Tech10 insert has already been used on rifles like a Mk18, an M4A1, and a Mk12, as well as other Daniel Defense platforms, after being introduced to the product by Neil McLean, known for the McLean Core sling.
Paul explains his background, having spent about 14 years with Naval Special Warfare as a gunner’s mate and weapons technician. During that time he observed problems shooters had when entering rooms, stacking on the opposite side of a door, and working barricades or shooting from vehicles, especially for right-handed shooters forced to work from the support side. Traditional sling attachment at the rear of the stock or at the castle nut created interference and awkward transitions. After experiencing these issues himself during training, he decided there had to be a better solution. That led to the development of the dedicated inserts for B5 and LMT SOPMOD-style stocks and the matching Swinger sling mount, intended to move the QD point into the stock cavity instead of behind the receiver extension.
The video then walks through how the Tech10 insert installs into a B5 or LMT SOPMOD-style stock. These stocks have a molded internal cavity and a 3/16-inch through-hole on the side. The T10 B5 Enhanced SOPMOD Stock Insert is designed to fit that cavity. It is placed into the opening and driven in with a dead-blow hammer or by hand strikes; the material is robust enough that normal installation force will not damage it. The kit includes the insert and a passivated 316 stainless steel pin. The pin is inserted through the 3/16-inch hole and driven flush on both sides using channel locks or a roll-pin punch. If installation takes more than a couple of minutes, something is likely wrong. Once installed, the insert is effectively captive; removal would require pushing it inward and driving it out with a hammer after taking the pin back out.
After the insert is in place, the T10 Swinger Sling Mount is added. The mount is a separate, solid steel component about three-eighths of an inch thick that snaps into the installed insert. Once attached, it pivots, allowing the sling’s QD connection to swing from one side of the stock to the other during shoulder transitions. This pivoting action supports moving from strong-side to weak-side around barricades or other cover without the sling binding. The system is presented as an alternative to mounting a QD plate behind the castle nut or using an HK hook at the rear of the receiver, both of which can cause the rifle to hang awkwardly or interfere with movement. The Swinger mount is described as simple, durable, and designed to be effectively permanent unless deliberately removed with tools.
Attention then shifts to the Tech10 BRAVO Sling, a two-point sling with steel hardware. The front adjustment buckle is machined from 316 stainless steel on a CNC machine. The adjustment motion is designed so the shooter pushes the buckle toward the rifle until it hits a sewn-in stop, then rolls the hand and pulls back to tighten. The sling webbing is reinforced with double box stitching at the rear of the buckle and bar tacks at key points. The sewn stop at the front prevents the adjustment section from running forward into the QD, eliminating the need for an additional slider. The sling is intended to be operated primarily with the thumb through a looped pull tab, giving leverage even when dexterity is reduced by cold or gloves. The host notes that the design reflects careful consideration of each component.
Paul explains that the pull tab assembly on the BRAVO sling is designed to break away at about 180 pounds of force to prevent snagging hazards during activities like room clearing, vehicle work, or diving into confined spaces. The sling ships with additional zip ties that will break at roughly 60 pounds for users who want a lower break threshold. If the pull tab assembly breaks or is removed, the sling can still be run directly off the buckle. The standard pull tab cable is about six inches long, and a seven-inch version is available for use with heavy cold-weather gloves, creating a larger loop for the thumb. The hole in the buckle is 3/16 inch, matching 550 cord diameter, so paracord can be used in the field to improvise or replace a pull tab. The pull tab webbing is 1.5 inches wide with a stiff plastic insert so it is easy to identify by feel behind the back.
The sling webbing used on the BRAVO sling has a minimum tensile strength of about 4,500 pounds and is impregnated with resin to improve abrasion resistance. The host references a prior test where two trucks were tied together with the sling to demonstrate its strength. Returning to the rear of the rifle, Paul shows how the Swinger mount behaves when the rifle is dropped or allowed to hang. Because of the geometry, the mount pushes upward and inward toward the stock rather than pulling away, reducing the chance of the rifle being pulled off the body or the QD failing. The face of the QD cup is designed so that the mating surface of the QD swivel rides on the face of the mount, keeping stress off the internal ball bearings. The area around the QD interface is sealed, further protecting the mechanism while the rifle hangs naturally at the shooter’s side.
