Black Ops Defense offers a full line of services and conversions for the HK G28/MR762 (HK417, M110 etc…). Anodizing, basic assembly, laser engraving/remarking, barrel threading, gas block modifications, civilian MR762 to military style G28 DMR/417 type rifle conversions and more.

Most conversions are done using a mixture of factory HK parts and high quality HK licensed parts. In many cases the factory parts are simply not available in the US or are cost prohibitive for most collectors. We are doing our best to bring you never before possible versions of the HK DMRs like the G28, M110 and 417. See below for details on each build.

Although parts pricing and availability changes all the time, currently, the least expensive way to build an HK G28 DMR civilian rifle ( Designated Marksman Rifle ), is to start with the MR762.

Other build options are available using original HK G28 parts, aftermarket parts or any other combination. Just let us know what you need. (Parts availability is very limited)

This conversion primarily consists of refinishing, re-marking/laser engraving the receivers and changing out quite a lot of the external parts. See services and parts list below.

Finally a less expensive and attainable G28 DMR option! Send us your MR762. We will perform the conversion and provide the necessary parts. (Contact us for complete packages including rifle.)

The parts are not necessarily factory HK but they are an extremely well made alternative to the nearly unattainable HK originals. They are also fully licensed by HK and have all of the HK logos and stampings! Side by side, with most of the parts, you literally can’t tell the difference.

Although parts pricing and availability changes all the time, currently, the least expensive way to build HKs new version of the militaries M110A1 SDMR, ( Squad Designated Marksman Rifle ), is to start with the MR762 civilian rifle.

Other build options are available using original HK and Geissele parts. Just let us know what you need. ( Parts availability is very limited )

This conversion primarily consists of refinishing, re-marking/laser engraving the receivers and changing out quite a lot of the external parts. We are also able to make the very specific modifications to the upper and lower receivers, to mimic the military’s ambidextrous version of the HK M110 A1.

Usually welding and manipulation of 7075 aluminum is not possible due to the stress cracking caused during the welding process. Using proprietary welding techniques and special welding rod, we are able to achieve strong, stress crack free, 7075 aluminum tig welds. ( contact us for more information on this special, very unique welding process. )

Using the above technique we are able to remove the forward assist, extend the rear section of the upper picatinny rail, mill down the “J” bolt release blocking feature and mill out the rear area of the case deflector. These procedures create a near exact replica of HK’s factory m110 upper receiver, done for the US military SDMR. ( Otherwise unattainable on the civilian market )

Likewise the lower is machined for the ambidextrous controls and the blocking features are added using welding and machining processes.
