HiTec Arms SD Suppressor Demo

Hey there folks! Today we get to demo the SD and SDK suppressors from HiTec Arms. These cans are designed to work with SD profiled barrels like those found on the MP5SD. There are a couple companies that make these barrels including HiTec Arms and Broad River Tactical. Today we are going to demo these cans on two direct blowback barrels and a radial delayed blowback barrel. Enjoy!
