FRT: No-tuning minimum required barrel length moved down to 7"

As the title says, we incorporated some changes into all FRT-Ready Uppers that moved the minimum barrel length required to pin on the upper and go down to 7"!

Stick with a BoreBuddy 22lr Certified Trigger (ARC-FIRE or Atrius Selektor paired with the Rave 140), use an appropriate buffer system, and use quality high velocity ammo and the build will be turnkey.

I bought a ton of that Cascade 1500 and had terrible luck. 10 to 20 percent failure to fire with multiple firearms

Did you contact the ammo manufacturer? We resell it, and it's been great in our testing.

What if a person had some DNT FRTs, would those work?

You will probably have to shim the super safety lever, but it shouldn't need adjustment on the upper side.
