I was pondering on different methods of silencing my G&G M14 and was wondering if expanding foam could be used to fill certain areas of the stock around the gearbox as there is a couple of dozen little holes there. As it says in the description of the Polycell stuff; "it shoots liquid foam deep into cavities, creating a long lasting seal, which insulates against heat, sound and moisture"

I could then file down the foam so it would fit the gearbox correctly/snugly. I could even apply this to the rear of the stock to fill out where I put my battery (to stop it from rattling around and reduce the boxy noise of a hollow stock) and the front end of the gun (as there are holes in the front sections which could be causing noise) if any benefit could be gained from it.

As a further thought, could it also be used to secure my barrel once my LRB is correctly set up, but then would it stop me from removing the barrel afterwards? Could the barrel be coated in a 'non-stick' coating such as Vaseline, silicone grease or another lubricant to prevent the foam from adhering to it?

Thoughts?

I already have a lot of my stock filled with packing foam so the reason for me asking this question is simply a "How can I make my gun quieter?" It's already quiet, but I think it can be better. This is the reason my friends know my guns going to break, I'm always trying out new things so I can I can get that little bit more performance by doing another tiny tweak or change.

I will have a think about what you guys have said and then give it a blast, the modeling clay sounds like it'd be good for around the gearbox.

If I followed that correctly Vindi, the plan is too slap filler into the places I want filling then place my gearbox (protected with clingfilm which is coated in grease to prevent sticking) into the stock so the filler can take the shape of the gearbox as well as the stock.

Then, when the filler begins to dry remove the gearbox and re-insert it. Repeat several times to ensure that the filler has molded the tracks needed for insertion and removal of the gearbox?

Vaseline and cling film... Liberal amounts plus liberal amounts of in and out afterwards... I feel sorry for people who haven't taken the time to read this properly and have skimmed to the bottom!

Still, I will be using the spare gearbox for this one. Just in case.

What do you think to using the expanding foam to fill the outer barrel though? To give it the stabilization?

I understand where you're coming from there Jute, the expandable foam is something that'd be done a bit at a time under controlled conditions. There's no way I'd just dump a load of that stuff in and watch it take over my rifle like a weed in an untended garden.

Rubberized paint ey? I've not heard of that, that's something I will have to look into!

I hadn't thought of the sound deadening effects that the Ghillie sock could have... It'd be quite easy to slide a wrap of foam around a good portion of the body underneath the sock. I will have to give this a try at some point

The list grows larger!

Electrical tape no?

I wish I could say I have thousands of plastic bags just lying around the house but I have a dog so all plastic carrier bags are appropriated for poop removal.

I hope to be able to give at least some of the ideas here a try as soon as I have acquired myself some more Airsoft funding.
