Thought this might help.
Silencers & Suppressors or better known as a “Can” are different, silencers typically use “wipes” or mesh packets and aren’t very useful in battle since you’ll only get one or two mags before needing replacement. Suppressors have chambers milled out of Steel, Aluminum or Titanium-(which is exotic) and these chambers, depending on design (not all can’s are created equal) essentially delay the ported gases while they exit the barrel. If you were to use a high-speed camera to record the exit gases from a non-suppressed firearm, the gases would mushroom outward which causes the sonic crack that makes the sound. When using a suppressor, these gases that normally expand as the bullet leaves the barrel are trapped inside the chambers for a delayed reaction.
Some suppressors actually do increase accuracy and velocity and do it very efficiently because they formulate the gases forward instead of expanding upward and downward into a mushroom. However suppressors do need some degree of lubricant to be most efficient, typically a few drops of water or grease is all that’s needed.
In order to get the quietest results, special ammunition has to be used in order to slow the bullet. This process does not cycle well in full auto with certain calibers, specifically 5.56 (.223). There are currently NATO cartridges that cycle but there are only a few variants available. A well designed suppressor should run both subsonic and regular ammo efficiently.
What Surefire claims of their suppressors is hearsay; it’s all sales pitch. In fact they’re quieter suppressors out there but one thing surefire does have is a newly designed “quick attach”, which I’m still skeptical about. Surefire however is not the only manufacturer to offer a quick attach device. The SEAL’s already use another that causes problems, so the quick attach in general needs improvement.
It is virtually impossible to suppress an M60 because with the rate of fire, the barrel gets extremely hot and there is no suppressor in existence that can dispate that level of heat. When exit gases are are held in the suppressors chambers, the gases are mostly heat and an effective suppressor should delay or hold gases (heat) for one to two seconds in order to reduce the sound - with an M60 or equivalant weapon the suppressor would overheat and malfunction. Also SEAL’s don’t use the M60 anymore, they use the M249 SAW “Squad Automatic Weapon”
.50Cals use suppressors all the time, the sound suppression equals about 40%, which is huge, if any one wants video and audio – PM me. Without a suppressor on a 50 it is almost unbearable, but with a suppressor ear protection is still needed but it’s less harsh.
Beretta M9 (92F): SEAL’s don’t use them either; they were phased out because of constant malfunctions. The MK23 SOCOM pistol (45 cal) was a possible replacement but is now in the process of being phazed out as well due to size, weight and because the 45 caliber isn’t the most efficient round. NSW now uses the SigArms P226 9mm. Size of caliber doesn’t necessarily mean more velocity or power, in the case of 45 cal which makes for a good suppressed cartridge because it's doesn't reach super sonic speeds like other ammunition, isn’t better then 9mm. 9mm has far more take down power and more velocity then 45, plus it weights less and because it’s universal – can be picked off the enemy.
Also SEAL’s don’t use the MP5K, there are many variants of the MP5 and the SEAL's use the MP5SD (retractable stock) integrally suppressed…meaning the suppressor is attached permanently and therefore quieter then a thread on. Also the G36 is more of a Law Enforcement sub.
M16’s: There are many variants out there; SEAL issue is the M14 (14.5” barrel) and the CQB variant called the Commando (10.5” barrel). One example why the Commando is effective, it’s shorter barrel allows one-handed operation for opening doors. Also there is no accuracy difference between the Commando and M14 – the Commando is actually more accurate. There are also sniper variants with longer barrels, these variants are very effective on the battlefield because, they allow a sniper longer ranges and the ability to use the weapon in close quarter situations (where other sniper rifles would be limiting) with a special attachment next to the scope that allows mounting of a reflex sight. Another advantage is the usage of 5.56mm (.223) ammo that like the 9mm is universally used. There was testing earlier on an M16 variant that had a slanted magazine well to accept AK mags but it never fed properly and was dropped. The XM8 will never replace the M16, it is very limiting and does not allow attachments of other devices like lights, lasers, sighting devises, etc. It is also not a Crane/SEAL developed weapon – it is contracted for Army infantry, also it will be a long time before you see XM8’s fielded within the Army.
As for full auto pistols, currently used is the F&N five seven because of it’s composite frame reducing weight and the 5.7x28mm armor piercing ammunition - due to the calibers small size, one regular size pistol magazine can hold 20 rounds. Coincidentally the new SOCOM pistol (yet to be released from H&K) will also use the same caliber in a switch-selected semi to full auto variant.
I’ll save the sniper and other weapon variants for another post.
enjoy & and hope it clears up any misconceptions.
