Silence

Looking for simple ways to make my mb01 a bit more quiet. I've hear of sorbothane and incresing piston weight. I dont think a silencer would do much on a spring gun and also dont want the extra leght on a allready long gun.

First, make sure your barrel to cylinder ratio is correct;
Second, make sure there are no leaks;
Third, use a stronger spring and cut of some coils to downgrade the FPS to the level intended;
Four, install an air brake on your piston;
Five, add a silencer with baffles.
I run my VSR with M190 AEG spring (which are shorter), custom piston with air brake, 430 barrel no suppressor and it's quieter than my friends G-spec with silencer on.

doesn't the airbrake waste power and are there any good tutorials. Also you cant get a well mb01 with AA hopup perfectly sealed its impossoble for me atleast

I lost 5 fps with a 15mm air brake, so neglectable to me.
Laylax vsr piston comes with air brake.

yea vsr... not a L96...


Anyway. Sorbothane pads (from airsoftpro) on piston and cylinder head worked great for me. Along with a 130mm foam filled silencer. It does more than you think. Then there's some fiddling around, diy mods. Coke can over spring guide to reduce twang noice, fill stock with foam are two common mods.

Also you can easly get 100% airseal with AA hopup unit. Just use the right bucking. What are you using now? I got brilliant results with both maple leaf macaron buckings and maple leaf hot shot bucking. 100% airseal and consistent. (Dont forget a concave nub if you use a similar setup).

thx for the great info i use maple leaf macaron 70 bucking and have the maple leaf nub the curved one dont no what its called. When i block the barrel and empty fire it feels good but right after i hear o powerfull hissing sound, so is it good seal or bad? I also have an o-ring in my piston head and a cylinder head with some rubber in it so there is no metal to metal. Will the sorbo still work and where do i put it im so lost lol

See above thread to get an idea of what a weighted and airbraked piston can do on a VSR system.

If you're going to run an airbrake do NOT cut any coils until you've tested how much the airbrake is going to slow the piston down. It can be quite dramatic. Also you need to consider spring length as well. Longer springs (like SBA springs) are more highly affected by an airbrake than a shorter one (like laylax).

I would like to run the airbrake system but i do not know how to make it or into what piston it is supposed to made in

I feel like the airbrake is a bit too much hastle but if someone would link s good post for sorbo id be gratefull. Also might shove the whole thing full of foam and try the cola thing.

Laylax makes cylinder head sorbo pads.

Airbrakes are great if you really want a quiet rifle, but it takes a lot of tuning to maximize performance with one.

The sound difference on a full airbrake that will completely neuter fps is huge, but with a shorter one that you would actually likely use? The difference is there but its not game changing. You can also play with tapering the airbrakes to adjust them as well, but I haven't gone that far yet.

Matching your cylinder to barrel ratio is probably the best thing for noise. With a .2g my rifle makes a crack and the piston slams into the cylinder head like you were dry firing. With .43g its more of a dull thud because the bb is leaving the barrel at almost the exact same time that the piston is completing its stroke.

Should be okay, considering O-rings are rubber. As long as it's not hard platic hitting metal. Get a short suppressor (so the rifle doesn't get too long) and have a friend shoot it a few meters away from you. (Make sure to use heavy ammo). It's always louder when you shoot it yourself 😉

About the airseal, wrap some ptfe tape around the base of the bucking when it's on the barrel. Should help abit. Also check for airseal in the cylinder itself.

I see people talk about weight adjusting and airbreak.
I've never tried airbreak in my mb01 so if you do try please let me know 😆
As for putting more weight on the piston, I tried it and it gave me a negative effect. Might just have been me, Idk. Again, let me know if it works out for you

You don't need an airbrake, you just need to muzzle whatever is vibrating in the gun. Remember, the stock and outer barrel are basically hollow. If the cylinder ratio is correct that'll take care of the 'pop' from the muzzle. You can dampen the gun with just about anything. I used a nice hard rubber to make my barrel spacers. They just so happen to kill any noise happening in that area. My rifle is also wrapped with that camo and just the addition of the wrap helped. You could fill the gun with a light poly insulation (like the stuff you get out of a jacket) and that would completely kill any resonance inside the stock. I didn't bother as it's quiet enough already. From 30 feet, you hear nothing, let alone at 275 plus. hahahaha

thx everyone for the advice. i might try this and get a silencer. but i do belive my cylinder to barrel ratio is good. what material do you suggest for the stock?
