Baffle stacks

Recommended Posts

I’ve made a shroud n need to put a baffle stack in it 

just wondered what’s people’s thoughts,I’ve read about different sized chambers and reduced hole sizes through out the stack but do you start with large chambers n holes n reduce towards front or other way round ?

Short. long. short 

So at the  barrel muzzle .first a short chamber .then a longer one (twice the length ) then a short one before the shroud exit  

Also ideally you have felt inside between the baffels  held out the way of the pellet travel with either a fine  mesh or easier is a plastic hair roller . (Cheap as chips from the pound shop .)

Yeah a decent reflex  shroud with say  a 6 inches infront of the muzzle can be just  as quiet as a 9 inch standard mod just  on the  muzzle  .especially if the shroud is vented at the rear near the breech  .

Yes  .just 1 or 2 small holes about 2 mm should be enough .

It allows the air to move rearwards down the reflex part (behind or along the barrel ) and out .with out the holes the muzzle blast would be  trying to compress the captive air in that section .

And basically wont  .with the holes its not captive and allows  expansion  in that direction .

Obviously the bigger the holes the more will be allowed to come rearwards  .but .you then have air blowing backwards towards the shooter and that can be a touch uncomfortable if in the eye.

A single 3 mm under the shroud should be descrete and not to in your face .

And will work .

 

Ps if your shroud doesnt allow air backwards from the muzzle dont bother  .
