My friend and I did some tests with different suppressors on a M16. You can hear it but its more difficult to hear the exact location of the shooter. Another benefit is that the sound is more difficult to pinpoint from distance. The sound will still be loud but a drop from 110+dB to 90-100 dB is a big difference for your hearing. The reason to use a suppressor (note the word suppressor, not silencer) on assault rifles is to protect your own hearing. Just sort'a wondering about the SOP for subsonic ammunition, since other than in very special cases it seems like a waste of weapon range and stopping power. It'd be quite pointless since the muzzle blast would be so loud you could just as well use full-power ammunition with a suppressor and pack 4x the punch. I just can't find any info on gas regulator valves on M4s).Īlso, I'm not talking about use of subsonic ammunition without a silencer.
For example the FN SCAR and Bushmaster ACR has a gas regulator valve that the user can adjust depending on if they use subsonic ammunition or not so that they don't have to change internal components because of ammunition-change.ĭon't think that's possible on the M4A1 though (someone please correct me if I'm wrong. Don't have silencers, m4's and my own different ammunition loads in this country. but i wouldn't have though it would reduce to being a third as loud.

Put the silencer on and it restricts it enough to work properly? (and of course, full power ammunition overpressurises it, leading to failure?)Īs for reasons for wanting to use subsonic ammunition in your M4 or other weapon, but without a silencer. I thought that the low power subsonic ammunition wouldnt work in the unspressed weapons, lets say a m4, due to the lower grass pressure not being enough to overcome the spring. Just trying to get a better understanding of things here, since information on the topic is hard to find, for basis to decide whether I should look more into proper properties of suppressed weapons using full-power ammunition.
#Subsonic 556 db mods#
Mods are here to make differences though, and I'm curious first and foremost: During what circumstances would subsonic ammunition be used by a soldier with a weapon capable of firing full-power ammunition through its suppressor? When storming buildings to decrease the disorienting noise? For 'absolutely-can't-get-noticed'-missions? For jungle warfare where fighting ranges are so short it's irrelevant if you use subsonic or not? It is fairly reasonable from a game balance perspective I guess, seeing the Russians use subsonic ammunition for their AKS-74UBN and its PBS-4 suppressor.
In fact suppressors increase accuracy and they increase muzzle velocity, however with the two main issues being a shifted zero due to altered center of mass for the weapon, as well as making it more front-/barrel-heavy, and increased malfuntion rate due to higher gas pressure.Īt the moment however I'm forced to choose between 900m/s loud and highly visible shots, or 320m/s silent and invisible shots. However as I understand it at least M4A1s, and especially sniper rifles (not that we have suppressed sniper rifles other than the KSVK in vanilla ArmA2, and that gun works as it should since it's a built in one, but just making clear) are usually NOT used with subsonic ammunition unless necessary since it has quite terrible performance, and absolute silence isn't as necessary as just not letting the target know where you fire from, or not realize shots are being fired until you have shot several times. It doesn't matter if I use a suppressed weapon or not as long as I have the right ammunition, since all detection values for muzzle flash and sound bang are defined in the ammunition. I've time and again got irritated on the fact that there's no 'in-between' for using a suppressor or not in ArmA2.
