Description
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.
We ended up having to make a separate part design for the 300 blackout chambered MCXs because the two cartridges are just too far apart, and making something that fits and works with both would end up in too much compromise on either extreme.
