What Is The Best AR-15 Sling?

Sling Drill Setup and Magpul MS1 Baseline

The video opens with a dedicated sling manipulation test designed to stress how quickly different AR-15 slings allow a shooter to get on target. The drill starts with the rifle slung behind the back, hands off the gun, then transitions into a rapid one-shot engagement on a large silhouette at roughly 15 yards. Three slings are selected for comparison: the Magpul MS1, a T-Rex Arms two-point sling, and the McLean Core single-point sling, all commonly used by the Classic Firearms team. Using the Magpul MS1 as the baseline, the shooter records times of 2.20, 1.95, and 1.78 seconds. While the Magpul delivers a solid best time, the shooter notes difficulty quickly finding and working the adjustment tab under pressure. There is also mention that the Aimpoint optic may need to be re-zeroed, hinting that some shots are not landing exactly where expected, though the focus remains on sling speed and handling rather than pure accuracy.

T-Rex Arms Sling Configuration and Performance

Attention then shifts to the T-Rex Arms sling, which is introduced as a clean, straightforward two-point setup. It uses a QD attachment at the front and is threaded through a B5 stock at the rear, creating a streamlined configuration that avoids snagging and sits comfortably in the shoulder on a 5.56/.223 rifle. Compared to the Magpul MS1, the T-Rex sling is praised for having multiple intuitive grab points that make loosening or tightening the sling faster and more deliberate when the clock is running. The same hands-behind-the-back, one-shot drill is repeated to keep the comparison fair. With the T-Rex Arms sling, the shooter achieves a best time of 1.79 seconds, nearly identical to the Magpul’s 1.78-second run. The segment emphasizes that while raw times are close, the T-Rex’s adjustment ergonomics and multiple contact points give it an edge in ease of use during dynamic manipulation.

McLean Core Single-Point Sling and Timing Results

The McLean Core (often referred to as MLAN Core) sling is then introduced as a hybrid single-point design with an administrative mode. In admin mode, the sling can be secured for carry, but it can also break away to function as a true single-point, giving the rifle full freedom of movement. This is highlighted as particularly beneficial for CQB and shorter rifles. The host explains how attachment point placement affects where the muzzle points when the rifle is dropped, contrasting the body retention of two-point slings with the maneuverability of a single-point. Timed drills with the McLean Core start around 2.42 seconds but quickly improve to a best of 1.70 seconds, making it the fastest sling tested compared to the Magpul MS1 and T-Rex Arms slings. A distinctive pull loop is identified as the key ergonomic feature, offering a positive, easy-to-find control that has not snagged or unintentionally released, even during use in wooded environments.

Final Thoughts, Future Tests, and Rifle Gear Rundown

After reviewing the timing data, the host explains a long-standing preference for two-point slings like the Magpul MS series and how the McLean Core single-point design changed that opinion enough for Classic Firearms to carry it. Plans are mentioned for a follow-up video focusing on rifle-to-pistol transitions, comparing the McLean Core against two-point options such as the T-Rex and Magpul MS, likely using a Mark18 with a QD adapter at the rear of the lower receiver. The video then shifts into a detailed rifle and gear rundown. The rifle features a Surefire Scout light, Surefire muzzle device, MLOK-mounted McLean Core sling, Tango Down grip, Modlite, Aimpoint T2 in a Scalarworks mount, Knights Armament rear sight and rail, B5 Systems stock and grip, a BAD lever, and a Magpul Gen 3 magazine. A Geissele flat-face two-stage trigger is highlighted, along with a Pact G2 shot timer used for the drills. The segment closes by noting apparel and accessories including a Classic Firearms hat and shirt, Walker Bluetooth hearing protection, and a Garmin Instinct watch.
