What's the point of a sliencer for most people?
Let me answer that question with a question:
What is the point to the noise of gunfire ? What purpose does it serve ? Why is it desireable ?
I for one can't think of one positive thing to say about the noise of gunfire.
So, I chose to do away with it.
Simple enough concept ?
You got a muffler on your car ? Why ?
"IIRC you need the stamp first to enable purchase?"
No, just the opposite.
You have to buy the NFA item first, because you need the serial number, vital statistics, manufacturer etc to fill out the form 4.
You pick out what you want, find a dealer to recieve the item, pay, the process begins. Wherever you are buying it has to do a transfer from them to your dealer. Unless of course you are buying an item right off your dealer's inventory. When your dealer gets the item you can then start your own paperwork (form 4). The dealer holds the item until the tax stamp comes back.
"And boy, do I not have $1,000 to spend on them!"
There is nothing on that website that costs anywhere near $1000. Including the gun. Out of all that stuff I listed above that I bought this year, none of it cost $1000, although the suppressed 9mm upper cost over $1000 including the tax stamp. You can buy a Gemtech .22 muzzle can for $299 suggested retail (Outback-II).
Something else to keep in mind is that there is no reason to pay retail for this stuff. You look at this stuff on the manufacturer's website and the prices listed are suggested retail. There are dealers out there offering this stuff for substantially less than retail. Here is a guy selling that Gemtech Outback-II for $275.

The last two suppressors I bought, I saw on the Equipment Exchange on AR15.com. I bought them both from Henry at TitleII Firearms in Pickens South Carolina for subtantially less than retail.
