Clearance isn't going to be an issue...so why not go 1.5"?
I have one approved from 1/13/16 for my AR57 and still haven't made it. Have an idea, just haven't taken the time to work on it...and still considering getting my $200 back instead.

I agree i'd go 1.5" and do first two 17-4 followed by ti or 7075 alu. if your machining your own baffles i'd do a ultra 7 style baffle ie. 1" cone to the 1.375" ish id of the suppress. it will allow for another cone or two and still offer good suppression. clipped obviously. similar to a VSR.

I'll resurrect this thread.
So I just bought a PS90. I'd love to SBR it; however the 9month wait on a stamp is less than appealing. I already have a SpectreII so I could use that if I did do an SBR. However, has anyone tried to build a reflex suppressor (almost like a barrel shroud in this case)? It would obviously still require a stamp; but no rebarrel and you would retain the additional muzzle velocity of the original PS90 barrel. It would be an interesting idea I think but more of a six of one half dozen of the other in terms of wait times regarding stamps and effort. Thoughts? |

Remember, the shroud is pinned to the factory barrel to get it to 26" OAL. So, if you're wanting to avoid the SBR stamp you have to first get it mounted correctly so that the firearm still functions, and then make it permanent to keep the OAL legal. |

If the can was mounted to the shroud it shouldn't be an inordinate amount of work. The flash suppressor area could act as an expansion chamber and there could be a baffle system going back towards the rear of the can. I've never built a can but that's how I see it in my head any ways. There seems to be enough areas on the shroud to index a can for repeat mounting.

I know you just bought it, but do you truly understand how it's assembled? (I didn't when I got mine...but figured it out when I chopped the barrel) |

With the right cones and clipping no indexing would be required since there would be no poi shift.
You can learn the best methods to build a can in the tutorial at. Https://form1suppressors.com/ |

You're going to have to remove the shroud to get to the threads. So it won't be there to mount the can to. I know you just bought it, but do you truly understand how it's assembled? (I didn't when I got mine...but figured it out when I chopped the barrel) Quote HistoryQuoted:

I absolutely do understand how it's built. But this design would be something that wouldn't require threading and it would index on the shroud. Albeit, I've never built a can. So a skilled machinist may have their hands full. But I'm quite sure I could draw it up to start the working model at least... |
