tapodThis is a new Mototech engineering Gascomp300. I never had the chance to use it because my Rattler Lt muzzle device/suppressor combo touches the adjustment knob. I waited way too long for this with no correspondence from the company and honestly forgot about it and now I can’t even use it. I decided to get a JBD omega valve instead. If you have any questions please ask. Below is the description from their website. “MCX GasComp300 will tune your 300 Blackout MCX of all gens and barrel lengths to shoot your supersonics at a very comfortable bolt speed, without all the annoying over-gassing. At the same time with a few turns of the knob, allows you to turn the gas back up to maximum so your can run your favorite flavor of sub-Sonics through your suppressor.” ****READ ME**** I am not interested in trades or face to face meetups, so please don’t ask. Also…. PLEASE look at the photos before purchasing from me. Unless I explicitly state it’s condition, assume there are blemishes. Ask questions or ask for more photos. I am happy to accommodate. ****READ ME****
