Col. Sanders:
The suppressor is a Type G rifle suppressor:

B&T will make any suppressor you want, but unfortunally you can't legally import one into the US unless you're a Government agencies or are a Title 2 manufactor of firearms. So you Americans are out of luck when it comes to B&T.
I dis-agree with you about semi-auto sniper rifles.
Bolt-action guns are much more reliable and more accurate than semi-autos and cost much less. Take an "entry" level sniper rifle, say a Remington PSS. The rifle with a Leupold Stevens scope will cost you about $1700. But a semi-auto Stoner SR-25 with the same scope will cost you close to $4000. And the Navy have had relability problems with their SR-25's.
Most semi-auto rifles will shoot around 1 MOA, the HK MSG90 is about 3/4 MOA but costs over $6000. The HK PSG1 is about 1/2 MOA but is even more expensivea at around $8300. Those are LEO prices btw. The SR25 Match is guarenteed by KAC to shoot 1 MOA or better. Price minus optics/mount is $3000. All commonly used bolt-action guns will shoot 1 MOA or better. The best will shoot 1/4 MOA or better.
Semi-auto rifles are great for hostage rescue and counter terrorist operations, were you can get of a fast second shot if needed.
Quote: "Why would they adopt suppressor technology when they are not out of the 1800's yet?"
To me, comparing the first bolt action rifles of the late 1800's with today's sniper rifles is, frankly, stupid. The may use the same mechanisme, but sniper rifles are a hell of a lot more advanced.
Take a new Ferrari 550 Maranello. The engine is based on the same principles as the first engines that were used around, say 1915. But the Ferrari engine is a lot more advanced, and I don't think anyone can dispute that!
Suppressors are in use by Special Ops teams already around the world. And the US Army Sniper School, Ft. Benning Georgia, are/have been testing/evaluating suppressor designs for sniper rifles.
