While firing a 7.62 BREN, my number 2 did a barrel change, I got up to move, grabbed the gun and the barrel fell off!

For a start a so called silencer (the correct term is sound moderator) will not hide the sonic boom of the projectile, only the report of the weapon. Even that is a bit suspect. I've done test myself with sound moderators on 223/5.56 LM4 Semi auto's as well as 7.62 NATO and 30-06 bolt action rifles, the amount of report that is reduced isn't worth the effort or expense. To effectively work, the sound moderator would have to be enormous to capture and silence the expanding gasses. The only time I found a sound moderator effective was with sub-sonic 22 rim fire ammunition in a bolt action BRNO rifle and 45ACP which is sub-sonic (830 FPS +/-) anyway.
There are four reasons for sound suppressors:

1)
No muzzle flash.
That justifies the troubles.

2)
Distant soldiers have more trouble telling the direction of the bullet's origin.

3)
Special subsonic ammo, useful at short range and when the opponent has acoustic sniper detection devices.

4)
Slightly improved accuracy.

The biggest problem with suppressors is nowadays that the rifle shoots into different directions with and without suppressor - due to different vibration of the barrel.

A sound moderator will also reduce felt recoil in heavy recoiling rifles, yes they can reduce muzzle flash depending on the sound moderator type

This is also true without a sound moderator.

This depends on the calibre. One of the finest was the silenced De Lisle carbine or De Lisle Commando Carbine, a Lee Enfield rifle converted by Sterling to 45 ACP calibre, in service from 1943 to 1965. The 45 ACP was ideal, as the standard round was well below the speed of sound and inherently a very accurate calibre.

During my tests, I've never found any evidence that fitting a moderator improves accuracy. I've fitted quite a few to different rifles including 22 lr BRNO, 223/5.56 Ruger Mini 14, 223/5.56 Vektor LM4, 7.62/308 and a 30-06 Mauser actioned hunting rifle, none of which showed any improvement in accuracy. The Mini 14 and Vektor LM4 actually opened their groups considerably. None of the rifles except the 22 BRNO displayed any significant reduction of the sound of the round going off.

Yes it will, a rifle will also change its mean point of impact if a bayonet is fitted.

Sound moderators fitted to some rifles might have some uses, personally I don't think their value would be that great.

I have poor experience with firearms (just a civilian here)... But I remember one thing clearly... Firearms are noisy as hell... I just hate noise. I get tired very fast and my head hurts when I'm dealing with too much noise... I dont know how soldiers deal with that. How can they put their heads right next to bullets exploding...

So I think that a silencer also adds to the comfort. I'm sure that a gun isnt supposed to be "confortable", it's not a car of a seat... But if a gun isnt noisy, you will be able to hear your surroundings better (it's good if there is enemies trying to sneak on you), you will be able to speak without barking to let the others hear you (better communication), you wont suffer from the echos when your fellow soldiers are shooting from inside a house/fortification etc...

Silencers are good as long as they dont damage the guns...

You hardly notice the noise, plenty of other things to worry about.

Define program. Like sniper school? Sure. Depending on the unit some have the older M21/24s and some have the M110.

The Barrett is being fielded by a few units who need to rellay reach out and touch someone. In fact the Army is working on fielding the Rafouss round for use against light armor. Just do a wikipedia or google search on rafouss.
I am fully aware of the Barrett being fielded both as a Sniper weapon and as a Scout asset.
I am sure there are lots of rounds being worked on that may or may not be fielded with the weapon system.
Quote:
As far as the expense of training... Not that much considering the Sniper program already teaches snipers about ballistics, scouting and a bunch of other things. I think they do some shooting too.
Um I agree. What I was saying is that the Army would not pay $50 per round, particularly when one must practice in order to be proficient.
Quote:
The rounds used by snipers are NOT surplus .50BMG. No way. Likely they are spending about $3-5 per round for match quality rounds. You cannot expect to consistently hit anything with surplus ammo.
Uh. Yeah.

When shooting the Barrett make sure you keep your mouth closed.

Well, I was focused on the noise...

boars dont shoot back... They may charge, but most just run like hell...

Going deaf is sort of getting use to the noise. I know what you mean I lost a little hearing my self, and i only did this **** for 3 years.
