Better cushion and more silent vsr piston

Any idea of make the vsr piston more quiet?, I have two designs for it and ...I need to draw them first

Update: the two piston heads, one cushion by a spring, and the other by a new design rubber
Tell me what you think

Look into the WASP or other pistons like it. Airbrake or a soft rubber cup are the two best ways to make it quieter.

I don't think your spring idea would work well due to the complexity and risk of it jamming things up.

The new EdGi SAP is fancy and quiet. High price tag like most EdGi parts though!

So I’ve never done this to any spring gun, but there is a mod (hammar mod I think it’s called, after the user here who created it) which involves using silicone caulk on the cylinder head. I have done it on a handful of AEGs and all of them hold up for years when done properly. It helps so much with the piston slamming on AEGs that it leaves sorbothane pads and other rubber pads in the dust. So look up hammar mod, or it may even be stickied in the appropriate section. Remember, I have not yet tried it on a bolt action, and have not heard of anyone who has, so try it at your own risk. I may also try it later!

Old school solution that works- cut a piece of mousepad (much denser than sorbothane) to the size of your cylinder head, cut the center hole, score up the cylinder head with sandpaper etc, super glue it on. Voila! no more piston slam. Silicone caulk will not stick to rubber rings or metal on the cylinder heads and WILL eventually end up in your hopup and barrel- really bad idea.

I have on my piston head that kind of sponge used for makeup and works really well indeed

Tssniper01 - wrong on multiple points. I suggest reading some stickies before misleading people.

The Hammar Mod has been tried and proven on AEGs. This means one application and no fuss for more than the lifetime of some other parts at a much higher cycle rate than a BASR. It lasts for years if done properly. It seems to have improved upon the efficiency of the old sorbo mod at least in theory and from data taken from other industries which translates well to ours. Go read the thread for details. I went back and dug up the old stickied post my self and it turns out, since my hiatus of lurking here, people have done it on BASRs with similar results.

So OP, if you have access to some 100% silicone caulk and feel confident, go find the how-to thread and give it a shot. It’s easy to do right and even easier to clean up and try again if you don’t get it right. When I did my 4+ cylinder heads half a decade ago I didn’t even use an electric drill, I just spun it in my fingers. So all you really need is the caulk and some saliva or whatever you want to use for lube, probably water. Hammars post explains it well. Don’t swallow the adhesive! 😂
