That's unfortunate.
Will Q make a 5.56 can?
Yes, we developed one already. The design focus was the military...strong, durable, compact, less blowback, very few parts, very few welds, simple and strong mounting systems, easy to mass produce, inexpensive, lower cost, etc. The silencer market went in the toilet, so we focused on the rifles and supporting those, and held back on the pistol Erector, the 5.56 can, and the integral pistol.
