I saw this on JR Machine Products’ site.
https://jrmachinepro.com/750-titanium-threaded-gas-block/ Seems pretty cool and a way to save weight for an OTB can. The only potential issue I can see arising is the back end of the can heating up quicker because it’s a part of the gas block. But cans get hot anyway so maybe a non-issue. Any drawbacks to this that anyone can see? Thinking about a 12.5 OTB build. |

I was thinking about a 9 or 10 inch long can. Using titanium for the last few baffles should help with weight. I suppose I’ll have to check alignment when it’s put together, but that has to be done anyway. |

I had read that a suppressor tube backset down the barrel doesn’t suppress as well as a tube that is more completely forward of the muzzle. However I don’t have a source to cite.
If I remember correctly the blast gasses are disinterested in moving backwards so it could therefore be reasoned that the muzzle should end as quickly as possible after the tube mount. The same tube mounted completely forward of the muzzle tested at a lower db rating than the same tube installed backset with the muzzle 1/3 into the tube length. |

View Quote That's correct for the same length of can, but with a reflex style like this you can get more can length for the same overall length. |

Could anyone tell me if an aggressive muzzle brake in the blast chamber of a reflex can would help with suppression?
You would think it would help more than a bare muzzle. Especially if the brake had two or three baffles and had a rearward-facing blast pattern. Can anyone confirm? |

I don’t know but they do say to work the gas pulse hard as quick as you can straight off the muzzle.
A brake should hypothetically strip and delay some pressure off of the gas pulse before it even expands into the blast chamber baffle. I actually don’t even know what a reflex can is. I guess that you could say that I don’t know the difference between my ass and a hole in the ground. But we’re all here to learn right? |

View Quote Helps a little with suppression, but helps more with longevity of the blast baffle. Does help reduced the amount of gas that's heading straight "down the pipe" by redirecting the gas and making it more turbulent |

Wow, I sure wish this gas block would have been available in 2008 when I made my first Form 1 suppressor. It sure would have simplified the construction and saved weight. I made a copy of this Navy patent from the Viet Nam era: https://patents.google.com/patent/US3776093A/en It's a simple one baffle suppressor disposable suppressor. I found out many years later that the reason it was disposable was that it was supposed to be made out of aluminum, not steel. Dispite its simplicity, it does suppress quite well, but is gassy. Suppression from a 20" bbl was comparable to an AAC 762SD also fired on a 20" bbl.

I’ve decided my next one is going to be a shorty for my 10.3’s. I had it mostly figured out until I read this.
I really like the looks of these. I wonder if an inch or two of barrel to reflex over would benefit a turbo k type can. It wouldn’t really add much weight. Or maybe I’m just trying too hard to come up with a reason to put this on a rifle. |

The older Barrett M468 6.8 rifles had a nice gas block/suppressor mount . The muzzle brake also acted as a forward boss to keep the bore alignment straight.
Worked really well. |

I hated going to weddings. All the grandmas would poke me and say "You're next". They stopped that when I started doing it to them at funerals.
