Haley Strategic Thorntail Offset Adaptive Light Mount Review

HSP Thorntail Offset
Finding the right place to mount a weapon light on a carbine rifle can always be a challenge. Different shooting techniques, shooting positions, gas systems, rail platforms and accessories all have an effect on where a weapon light is mounted. In the latter part of 2011 Haley Strategic teamed up with Impact Weapons Components to create a series of light mounts. The mounts were designed to complement modern weapon manipulation, accessories such as lasers and IR illumination and leave room for proper hand placement. From their very successful genesis to the present, the mounts have continued to evolve. The Thorntail and the Dropwing were the first mounts available. The Dropwing was designed to attach to a rail via the rail slots and has various ring sizes to attach to “tubular” flashlights. The Thorntail was designed to attach to MIL-STD-1913 rails and is tailored for short barreled rifles. The Thorntail mount also utilizes a ring attachment method and was designed to push the weapon light forward to leave space for proper hand placement. The next mount that Haley Strategic launched was the Mil 620 Light. The light mount was designed for the Surefire Millennium and 620 series of lights.

Haley Strategic Thorntail Offset Light Mount
The Thorntail Offset mount was launched by Haley Strategic in October of 2012. The Thorntail Offset mount is a canted section of picatinny rail that attaches to a MIL-STD-1913 rail. Though the mount was designed to be a platform for weapons lights I found that it could also be used for back up iron sights as well as red dot sights. Like all the other Adaptive Light Mounts, the Thorntail Offset was designed to be extremely low profile.


The Thorntail Offset mount is marketed as one of the lowest profile and compact light mounts on the market. Here it is compared to a similar mounting solution.

The Thorntail Offset mount is machined out of 6061 – T6 aluminum (Ultimate Tensile Strength 45,000 PSI)…which is a very strong grade of aircraft aluminum. The Thorntail Offset mount weighs 1.06 ounces. Haley Strategic includes a 9/64 Allen wrench to assist in mounting. I torqued the test sample to my Troy rail at 10 in/lbs and had no movement during testing. Haley Strategic recommends using Loctite to keep the screws from coming lose. Be aware that if you are running a piston gas system make sure the heat isn’t venting directly on the mount/light.
After testing the Thorntail I found that I was most efficient and comfortable with my light mounted in the 11 o'clock position.

I traditionally like to run a light at the 12 o'clock position. By shifting to the 11 o'clock I found that had a better field of view through my red dot sight.

After watching the Haley Strategic promotional video, Travis made a point to demonstrate the Thorntail Offset mount as a possible platform in which a shooter can mount back up iron sights. I was anxious to try this out. The first thing I noticed is that the sight does not sit directly over the bore. For close up shots I didn’t find this to be a problem. From the prone position at 100 yards I found that if I held an inch to the right I was able to accurately hit what I was aiming at.
The Thorntail Offset mount proved to be an awesome platform for Lucid's new red dot.

Due to the size of the scope mount the only place to attach back up sights was on the rail. The gun needs to be canted a lot more but if you are lacking a quick detach scope mount and you still want to use your iron sights...this is a solution.

Streamlight TLR1S mounted on my Remington 700 SPS tactical. If you live in a jurisdiction that allows you to hunt predators or feral hogs at night the Thorntail Offset allows you to utilize your existing lights. A green or red lens paired with the Streamlight TLR1S would be an awesome combination.

If you live in a jurisdiction that allows you to hunt predators or feral hogs at night, the Thorntail Offset would allow you to utilize your existing light…granted you had a place to mount it. A red lens paired with the Streamlight TLR1S will be an awesome combination for calling in coyotes at night.
Final Thoughts.
There is no question about it, Travis Haley did a wonderful job designing the Thorntail Offset mount. Impact Weapons Components sourced excellent material in manufacturing the Thorntail and the machining is second to none. The Thorntail Offset is an excellent mount that gives a shooter a lot of options in regards to configuration and I look forward to utilizing the mount on other weapons platforms. Without a doubt Haley Strategic is building an awesome portfolio of products. Navigate on over to the Haley Strategic website to check it out. On my way to the Haley Strategic website I stopped by theMARSOC Foundation website and made a donation.
