All you need to know

2-Position bolt plate

The magnetic dust cover and rear-placed bolt plate make on-the-go hop-up adjustments easy without having to hold the charging handle. Or, set the bolt plate fully forward—it’s your choice.

A word from the DEV

"When working on the SSR4 Mk2, we saw it the same way you would: We need gear you can count on 100%. We took the strong foundation of the airsoft AR platform and made it sturdier and smoother to handle. We got rid of the annoying wobbles, completely reworked the trigger (arguably the most important part of any gun), and refined the hop-up. Long story short, we gave it the attention it needed to shine, while still keeping it reasonably priced. And we weren’t afraid to throw out the “real-steel” rulebook, going for designs that simply make sense in airsoft. Plenty of people on our team, with years of experience, had hands on the Mk2 project. It’s a rifle we are proud of, in the end. I’ve personally been at this for nearly two decades, and it simply makes me happy to bring some of my experience to your hands. I hope it’s everything you need it to be, and more."
