Thanks for the input! I will either move the first baffle or extend the brake.whiterussian1974 wrote: ↑Sat Jan 11, 2020 5:31 pmI didn't see an answer to this, so I'd add my $.02 and say that I'd have the 1st baffle nearly kiss the brake. This would create a semi-enclosed blast chamber and also limit throat erosion on your blast baffle. Especially if the opening is just under the OD of your brake.
Also, why is your final baffle so far from your endcap? That is your lowest pressure Region. So you should have the MOST spacing there, not have it encroach upon the neighboring baffle.
You could also machine a cone on you endcap for the exit. Just a small .25" or so. I've seen many Builders include that.It helps with pressure retention, and also "smooths" the escaping gasses to increase Duration and thereby lessen Amplitude of the Atmospheric Disruption at Discharge.
Hope this helps.
As far as the last baffle to end cap spacing, that was an attempt to have a substantial amount of thread engagement on the end cap and keep the baffles all the same. I'm reconsidering the end cap design and will probably make some changes there.
Everything I have read seems to indicate that the baffle spacing should decrease towards the end of the suppressor, correct me if I am wrong but it sounds like you're saying the distance between them should be greater towards the end?
