    Just got back from the engraver. Had a pile of cans, SBRs and and SBS to get laser engraved after a philatelist spree last month. Three of the cans started out as solvent traps from the exotic land of China. Did you know you can turn those things into silencer? Who knew right? Still waiting on a few parts to finish up some of the higher powered cans but I got two of the guns and silencers finished up today. I'm pretty much putting a dedicated silencer on mst of my AR's. The two pictures are my

    CMMG Banshee bolt and barrel upper on a standard SBR lower with Glock mag adapter. Its got one of those big Chineseum $40 monocores. Its big and because of that its quiet. Sounds about the same as my AAC TiRant45 on a 9mm. Totally hearing safe and a pleasant tone. I had doubts about it after reading up silencer forums from "experts" who have never built one. They are wrong BTW.

    CMMG 5.5" .22LR AR upper with side folding stock. Also an SBR . Real nice shooter and its got a Chineseum 9" long 1.70" wide K baffle silencer with 9 baffles . Basically the same design of baffles as my AAC Tirant. That thing is ridiculously quiet and I would expect so with that much volume. No FRP to speak of. Its considerably quieter than my Silencerco Spectre II but I would expect it would be doing something with 10X the internal volume.

    That is a 12" KeyMod rail from Mentium USA. $69. I doubt they are actually US made at that price point but they are good, light rails and it fully clears the 1.70" diameter silencers. Not by much but it does clear. I needed a rail I could remove with the can in place . That one does the trick.

    9”L x 1.7”D .22 can? That’s HUGE!! But as you said, that thing should be the quietest .22 can in existence haha.
    I had a custom 4.5” CMMG based .22lr upper which I ran my SS Sparrow on and it was awesome. Almost wish I had never sold it.

    Agreed, the larger can looks better.
    This was mine, 7” TRX handguard fit well with the sparrow

    Where'd you find that big monocore? Only ones I have seen are 1.3" or so by 6"...

    I've found, IME, the baffle/core bore to have little effect on the sound compared to the endcap bore. As long as the fit/finish is solid, most come with a nut and a cap that can be drilled. At least mine have. I got one that's tight as a drum. Really nicely made. Then I got a black one that's sloppy as a two dollar whore. Curious about the quality of the monocore you pictured above.

    I was really surprised how good the quality was. Perfect bore centerline. I wouldnt call the threading the greatest. Good but not class A tight. I bored the end cap 10.5mm and the bullet sails right through.
