I know this is not the best choice of rifles, but it's what I gots for a number of reasons, so don't ask. Since the barrel is not threaded, I used a piece of 2" PVC lined with a bit of EVA foam to make it snug to the 'moderator' on the MCX. This worked better than I thought, although it took a bit of experimentation and gluing the foam inside the PVC was fun. I'm using high density polypropylene mesh for my air dispersion/sound dampening. Cutting the mesh to size was easy, but my bore holes are turning out to be problematic.
I read a couple of excellent threads here and got some good ideas. I should have lined the entire PVC tube with EVA foam, although I think it's a bit too dense for sound dampening. I'll probably still do this anyway. I also left an air gap between my rifle exit and the first layer of mesh.
I was reading about the importance of volume, baffles and sound dampening. I definitely have volume, sound dampening will be addressed, but I don't think the mesh will be nearly as good as baffles. My force is low, so I'm hoping the mesh and volume will give me what I want, until I can get a PCP that meets my needs. I was going to drill some side exhaust holes at the end of my moderator, thinking more exhaust volume was better, but based on the threads I read, this did not seem to be the case. Once I solve my bore hole issues, I'll test v 1.0.
Assuming this isn't as quiet as I'd hoped and for a future PCP version, I need to explore baffles. I'm thinking of rolling my own with a 3D printer, but I'm a little lost on the mechanics and design. I'd read that 2 to 4 baffles is ideal, with some spacing (air gap) in between. I was thinking that my mesh would make good spacers, as it's fairly rigid and should add additional dampening. Do I need to fasten the baffles in place or can I just use spacers/friction to hold them in place? I'd also read about people using springs between the baffles to further reduce noise, but this seems like overkill at 16 fpe.
Any thoughts on the above? I want to take care of some small vermin BTW, the four legged variety.
