SHOP NOWThis video showcases a custom H&K M110A1 SDMR-style rifle built to mirror the current U.S. Army and Marine Corps configuration. The hosts walk through its clone-inspired components, Weapon Works’ one-of-one Cerakote finish, the HuxWrx HX-QD suppressor setup, optics and accessories, and the platform’s modern military role and contract history.
The video opens on the range with the hosts presenting an H&K M110A1 configured as a Squad Designated Marksman Rifle (SDMR) and as a close stand-in for the Compact Semi-Automatic CSASS program. They explain that this rifle mirrors the U.S. Army and U.S. Marine Corps configuration and is intended as a clone-style build. A sound suppressor is initially missing, and a guest named Blue arrives to deliver it, setting up the focus on building a detailed, clone-correct M110A1-style rifle.
Blue from Weapon Works explains that Weapon Works is primarily an OEM Cerakote applicator based in Burlington, North Carolina. The shop focuses on high-volume production and limited-edition runs for manufacturers rather than one-off jobs for individual customers. He notes that a project with this level of detail requires more time and infrastructure than they allocate for single firearms, so they would only repeat it as a manufacturer-run project, such as if HK USA requested a batch. This particular rifle is described as a unique, custom piece created specifically for Classic Firearms.
After unboxing, the hosts install a HuxWrx HX-QD sound suppressor on the rifle. They describe it as a flow-through, all-steel can and the closest practical option to the device used on the military M110A1, while acknowledging it is not an exact one-for-one clone. The HX-QD uses reverse threads, which they point out as a distinctive feature. With the sound suppressor mounted, they comment on the overall appearance of the rifle and transition into a closer look at the rest of the configuration.
The rifle uses a Geissele rail derived from the G28 pattern, forming the basis of the M110A1 configuration. The hosts emphasize the rigidity and proven performance of the Geissele system for mounting accessories such as clip-on thermals and night vision. The rifle is equipped with Troy 45-degree flip-up sights and a SIG Tango6 optic featuring an appropriate reticle for 7.62x51mm. The optic is mounted in a Geissele Super Precision mount. Additional details include an ambidextrous fire selector, a Geissele charging handle, and a Harris bipod. The Cerakote color is described as somewhere between FDE and coyote, likened to a “German mustard” tone.
The discussion shifts to the background of the M110A1 program. In 2016, Heckler & Koch received the contract for the M110A1, which effectively replaced the Knights Armament M110, based on the SR-25 platform. The hosts note that the H&K system is roughly three pounds lighter and about two and a half inches shorter than the earlier M110, with a fully loaded weight around 15 pounds. They mention an initial contract value of about $44 million followed by an additional $34 million in 2020, resulting in nearly 6,000 rifles being delivered to the U.S. military.
Attention returns to how closely this rifle matches the issued M110A1. The hosts highlight clone-correct engravings, including “HK Defense Inc.” markings and the M110 designation on the receiver, mirroring the contract guns. Weapon Works has stated that this configuration is a one-of-one custom build and will not be duplicated unless HK commissions a production run. The hosts mention that the rifle has already been test-fired and broken in, and that it will be cleaned and prepared for whoever ultimately receives it, emphasizing its status as a unique, historically inspired configuration.
In closing, the hosts reiterate their appreciation to Weapon Works for making the project possible and note that someone will eventually own this M110A1-style clone. They demonstrate the use of the 45-degree offset iron sights as a backup if the SIG Tango6 optic fails, rotating the rifle to show how quickly the shooter can transition from the primary optic to the offset sights. They briefly contrast this with a traditional 12 o’clock sight setup and encourage viewers to share photos or videos if they end up running the rifle at the range or storing it in their safe, before signing off.
