IIRC Griffin was doing a three lug style QD mount for rimfire. QD on rimfire is dumb tho. Its a good way to get shit carbon locked in place.
Sparrow is great, cheap, quiet enough, and has an internal shield to help with carbon locking. SiCo switchback is considered one of the quietest cans available. The dead air mask was 'the best' before that. The rugged oculus is great, their mustang is good too as long as you don't need magnum rating The OCL Titanium 22 and Energetic Nyx are lightweight and also very quiet. I also have a Texas Silencer Company (now known as Lone Star Silencers) scoundrel that I specifically got for my 10/22 with a tacsol x-ring barrel so I can break it loose from the threads without having access to the bottom of the can. That one is great, while its basically a sparrow without the internal shield, I can twist the monocore inside to break any carbon loose.
