shockwave
In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance. When a wave moves faster than the local speed of sound in a fluid it is a shock wave. Like an ordinary wave, a shock wave carries energy, and can propagate through a medium; however it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium. In supersonic flows, expansion is achieved through an expansion fan also known as a Prandtl-Meyer expansion fan.
Unlike solitons (another kind of nonlinear wave), the energy of a shock wave dissipates relatively quickly with distance. Also, the accompanying expansion wave approaches and eventually merges with the shock wave, partially cancelling it out. Thus the sonic boom associated with the passage of a supersonic aircraft is the sound wave resulting from the degradation and merging of the shock wave and the expansion wave produced by the aircraft.
When a shock wave passes through matter, energy is preserved but entropy increases. This change in the matter's properties manifests itself as a decrease in the energy which can be extracted as work, and as a drag force on supersonic objects; shock waves are strongly irreversible processes.
Hey Folks,
I have a like new Shockwave pistol brace, AR pistol tube, spring, and buffer for sale.
$40
Willing to meet in Salem, Monmouth, or Corvallis.

Why do I buy these guns I am never going to use? :rolleyes:
This is new and unfired, with a $150 SB M4 Stabilizing Brace Kit installed.
Also a scope rail and a Green Laser..I will also include a new OPSOL Mini-Clip so you can shoot the Aguila Mini Shells...
I just took this in on trade, and have zero interest in it, it turns out. I know little about it. Seems completely functional and GTG, however.
$225 OBO. Transfer in Gresham or inlying Clackamas County.
I've got 1000 round of American eagle 55 gr brass cased .223 I would like to trade for a Mossberg shockwave. Would like to just do a straight trade, although if you have extras like a brace installed already we can talk about extra cash or ammo.
For sale/trade is a Mossberg Shockwave chambered in 12 gauge. I recently purchased this used and have not fired it. The previous owner did shoot it, but it hasn't been shot a ton. It'll come with the original box and lock.
Cash price is $275 and the transfer is on the buyer. Trade interests...
I’ve got a mossberg shockwave with pistol brace (+original birds head grip),accessory rail, mini shell adapter, 3pt sling, and 4 mostly fill boxes of buck shot and slugs. Not even a box of shells through it.

I’ll pay transfer fees for full price offer at my FFL. Price is OBO
Here’s a few guns I’d rather trade into something real nice. Sig has original everything , Mossberg comes just as you see.

4 magazines
Box factory warranty card inside

Got this AR pistol on a whim some years back at the expo in Portland mostly preassembled. Got the upper from one vendor, and a lower from another. Shot it a few times, never fell in love with the pistol platform. I like big butt(stocks).

New, never used Shockwave blade pistol brace and tube. Came installed on a complete lower I ordered as I had to order it with some form of brace. Already had a different brace I wanted to use and so this came right off after opening the box. No scratches or dings. The one thing I thought...
Barely used Mossberg 590 Shockwave 12ga up for grabs.
I fired a box of 00buck through the shotgun, cleaned it, and it has sat in my safe ever since. No original box however.

Serious buyers please leave name and number in PM
Thanks for...
