Curiousity about Silencers

I have no prior knowledge to sniper rifles. Do not own one nor have I ever shot one, which is why I am asking knowledgable users such as this forum.

My question is about silencers. In todays battlefield, are they used? For example, do insurgents in Iraq and Afganistan have silencers on their rifles?

I understand the advantage to a silencer, but what are the disadvantages and why wouldn't all rifles come with them?

Also, for those who don't use silencers, how loud are the rifles? In movies like Saving Private Ryan you could hear the guy on top the tower pretty well, would it be like that?

A small correction, for every third figure on the decibel scale the sound is doubled. A typical suppressor will do some 27-33dB in reduction. 45 was either a bit optimistic - or simply fantastic. :wink: Granted, some suppressors, like B&T and KAC, can operate as wet suppressors. And that can reduce another 10dB in a best case scenario. The difference between a wet and dry Impulse IIA suppressor on my Mk23 is huge. With it dry you still get a slight riniging in the ears. Wet sounds like a extreme fart.

As for supersonic loads, the sound of the expanding gases will be heavily reduced. It's this sound you with most ease can use to find the direction of a shooter. The sound of the supersonic crack will still be there, but it is very difficult to use for locating the shooter - at least with your own, human ears.

As for reasons to why suppressors aren't used by every grunt carrying a weapon. Well, they're expensive. A good suppressor can cost as much as a decent rifle. They are bulky and heavy. On my Remmy I have a 40cm long telescopic suppressor. That mens only 10-12 cm extends beyond the muzzle, but it's stil adds a significant weight to the rifle. And weight is a problem. Alas there is no such thing as a light weight suppressor with a long service life. The sad fact is that steel is an excellent material for both tube and baffles as it's very durable and resistant to heat, and not awfully expensive - but it's heavy. Aluminium is light, fairly cheap..and it melts when you shoot with it. It's lifespan is too short to be practical to grunts as they'd burn through a suppressor with alu-baffles in less than a week. Titanium is the last and best option. Light weight, quite heat resistant - but expensive as hell.

I expect my all-steel Impulse IIA to live some 20 000 rounds since I usually shoot it wet. The alu-suppressor for my Remmy...maybe 4-5000 if I'm lucky.

The point of impact WILL change. How much is hard to tell until you trie. A 400g object on your muzzle will of course do something to the harmonics in your barrel. Most often it will dampen the vibrations - which might mean a tad tighter group. Some people get crap accuracy with suppressors on. The reason is obviously that the extra weight on the muzzle - for some odd reason - change the harmonics for the worse.

It's all about metallurgy - and that's not my strongest field - but I've been told that poor accuracy with suppressors usually mean sloppy work when the barrel was made. Supposedly it's the same effect you might experience if you flute a decent barrel and realise your new fluted barrel wouldn't hit an elephant at distances you might as well throw your rifle.
Maybe I should've pointed out that I was refering to rifles with free floating barrels? And not assault rifles? And, of course, if you have a 16" long, 1" straight barrel, adding a 100g suppressor wont do much. There will be a theoretical change - but not enough to make a difference.
