First shots through the @irregulardesigngroup Hesychia Sixxk. First impressions are really good. Not a whole lot of gas to the face with this string of fire. Recoil impulse was nice with a fast dot return. I may go up in buffer weight to fine tune this setup. I had to move the light bar back one slot because the can is about an inch shorter than the rc2. Thank you to @sean_bernstein0326 for helping me get the right can for my setup. I had lots of questions and he was a huge help. And thanks to @sporting.goods.discounters for getting this to me so quick. If you’re looking for a new can, it would be hard not to recommend this one. #citizensupplycage #suppressed #mk18 #rangeday #tigerstripe by @sean_bernstein0326

Throwback to when we were at The GOAT 2.0 and @sean_bernstein0326 showed us just how compact the 556UK actually is. Oh yeah, and it’s pretty quiet too. 🤫

Rumor has it we have one on the shelf. 👀 Drop in tomorrow and check it out. taken in BluCore Shooting Center by @sean_bernstein0326

IDGs 7SIX2 series in both HUB and Hesion Bow are in full production and we will have a decent number of units available for the drop on August 31st.

We’ve had tons of customer feedback from the live demos we’ve been doing across the country that this suppressor is no joke. We took elements from the 556UKs internals and the flow characteristics of the SIXK to make this hybrid suppressor a highly versatile option for both 5.56mm and 7.62x51 and x39. Not meant to manage sub sonic munitions, but that can will come later.

The website will be hosting the specs soon! Reach out to your dealer if you want them to carry it! taken in Cincinnati by @sean_bernstein0326
