It worked perfectly with an aero build, just oil and use certain charging handles. - CMMG, Inc 22LR AR Conversion Kit, Bravo, 10 Rounds

Some reviews say it doesn’t work for them, but I made sure to oil it before firing it the first time (spring, guide-rails, etc…) it surprisingly worked flawlessly without any jams. It doesn’t like some charging handles so try to stick with mil-spec style ones, not radian raptors or anything fancy.

One minor nitpick is that when charging with the aero breacher charging handle, you have to push the charging handle back forward, instead of just yanking back and releasing. (stick to mil-spec to avoid this, or the one they sell for this kit)
