I finally have my dream rifle complete and back in my possession. This is my MR762 turned Hk 417 Assaulter build made by Black Ops Defense.

Wes Pritts and his team were very professional and knowledgeable and I completely trusted them with my most expensive, investment grade firearm. I highly recommend Wes and Black Ops Defense. He spent countless time on the phone and emailing me. He is passionate about Hk and highly skilled. I just can’t recommend him enough for all of your Hk builds. This thing is SO perfect. As far as I am concerned this IS a factory Hk gun -it was done so well by Black Ops Defense.

13” SBR
RAL8000 anodizing
Eotech & 5x magnifier
Surefire scout light

Very nice build. I am very fascinated with 308 SBRs. I think I want one one day but not sure if I’ll like the loudness and muzzle flash

For the 762 Waffe Burke gas block, what setting must it be on for SBR un suppressed and suppressed? Is the 2mm gas port a part swap out or was that custom work for the gas block?

Thanks for sharing your pics. It is fun to see how beautiful our HKs turn out when we customize them.

I’m also fascinated with what 308 can do from a 13” barrel. I know lots of people like to dog it, but I am more a glass half full guy, when it comes to 308 out of a 13” gun. I have other SBR’s…. Rifles are just loud to me. 🤷🏻‍♂️ I suppress everything for the most part, however. I like fireballs and loud guns, too. 😎

I’m not 100% sure on the settings for the Waffen Burk. I will study up on it and trial by error, I am sure, once I first go out to shoot and zero this gun.

I had Black Ops Defense bore out the gas port in the barrel to 2mm. This is the recommended gas port size for a 12” or 13” MR762 sbr build. This, in conjunction with the adjustable gas block, should allow me to achieve functionality and reliability both suppressed and unsuppressed. Search HkPro forums and you will find a lot of information on the 2mm gas port size and tuning these guns just right. 👍

Thanks again for commenting. It’s definitely a little heavier than my mk18 😂 but it’s not bad - and it is firing bullets 3x as BIG! 💪

Again, this gun runs one hundred percent 100% and would expect nothing less from an Hk MR762. With a 13”, you want go do 2 things: Waffen Burke AGB and have your mr762 gas port in the barrel bored out to a total of 2mm. I’m using a chimera 300 by silencerco that I purposefully researched to buy specifically to run on a 308 SBR as the suppressor is built like a tank and has no barrel length restrictions for 30 cal 💪😎.
