Check out Delta P. They make what you are talking about minus the keymod? Do you want keymod on the suppressor? Look up the delta p brevis.

They are the ones who gave me the idea. They are fully 3D printed. Pretty cool cans. I’m looking more at the form1 build it yourself route |

Shout out to bam machine! Their tubes look great. Threading job is good too.

Man, that does look like a cool tube. The part that gets me is that adapter. You could have had a smaller diameter and used that extra inch or so to stick another baffle or two in.
I do like the engraving though. I don't have a solution to make it shorter, but the adapter alone seems like it may defeat the purpose. |

What’s the ID and what cones are you planning to use?
Can you post or IM me Bam’s contact info please? What’s the weight of the tube, end cap, and adapter without the key mo? Thanks |

im looking at this, and im admittedly new to this subforum, but what's the point of the inner tube? especially with what looks like a large empty space between the inner and outer tube? wouldn't the baffles go inside the inner tube, so the outside tube basically doesn't do anything?

Porting the spacer would allow expansion gases into the outer tube, theoretically shorter spacer equals shorter tube.
Internally stackable baffles compressed between the end caps would eliminate the need for an inside tube, allowing for a touch more space.  Attached File |

Does anyone sell SS/Ti cones for BAM’s 2 inch tube?
Or would you put cones in the inner spacer tube? Kind of confused |

Kind of confused For subs (especially larger calibers), yes, I'd probably fill the tube Supers is where the coaxial can really shine. My personal issue is this is just a generic coax design. The end result is all up to the builder. Unless your extremely experienced in this science you'll just be making your best guess at baffle counts, spacing, and, most importantly, how to port into and efficiently use the coax volume. It's not as simple as porting the blast spacing and calling it a day. |

Did he have cones on his site? I didn’t see any. On a similar note, does anyone know of anybody who can make custom (non-drilled) cones/cups? I need some large aluminum ones about 2.75” in diameter and I’m having a hell of a time finding something I can use. Not trying to hijack the thread, anyone is free to IM me if they want. |

It could do well, but a properly made 1.5x6 will do great. Just adding girth doesn't compensate for lost length. As for custom cones, I think there are only a couple members (here and on the form1 forum) that do them. Depending on volume, you could have an e-shop do them. Cost will be high, though, for limited runs. |

BAM doesn’t sell 2” anymore and won’t be stocking them, same for reflex mounts

a grease gun tube is about 2.25"OD. there is a difference between the cheap ones n wall thickness. you want a quality one with cut threads for the end fittings. the thinner cheap ones are just pressed threads. best guess is .07 VS .055 wall thickness. But I'll be darned if i can i can find freeze plus. nearest were 2.25, same as the OD of the tube and MAYBE i could make a cut, squeeze down and weld to make fit. But then I did a weight check on probably parts and i was seeing 25 oz or more. Seeing as I don't have a way to thread 2.25" tube and no one to do it for "free" , I was having to look at welding or using small nuts and bolts or rivets to attach end caps. figuring in $200 tax, i decided to just save up for a commercial one and not worry about it blowing up.
BUT I still think with all the diameter room on at least AR's, a 2"+ diameter to get shorter length would be worth exploring |

From what I have read, longer is better than fatter when it comes to sound reduction. Most fat suppressors have the coax design that why they are able to get away with being short
