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.
Picked this up recently on a whim and I like where the safety is on the 870 platform better. This has seen zero rounds and has just sat in the box.
Doing a catch and release with this one. $475. Just want what I paid for it. Transfer at either Pantel Tactical, Sound Loan, or Precise Shooter...
I have a brand new in box Mossberg 590 with 20" barrel and 8+1 capacity. It has a bead sight and bayonet lug. It also comes with a factory pistol grip as well as the box and paperwork from the factory. Nothing is wrong with it, I've just purchased two 590s in the last couple of months and...
I was stupid and impulse bought the shockwave for $550 last year.
I have never fired this thing. Took it out of the box and put on a nice rubber sleeve. Thought that I would go have fun but life ended up taking...
This is one Firearm in a sizeable collection available due to a inheritance from a family member earlier this year. We are looking to sell the firearms and accessories and are not looking for trades. Thank you for not making trade offers. My father was a collector and but had not been shooting...

Recently got a Smith & Wesson Shield 2.0 9mm with Crimson Trace light and laser combo for a daily carry. Waiting on my CPL background check to go through and my StealthGearUSA IWB Mini to get finished.
Also recently picked up a Mossberg Shockwave and a KAC SR-15 lower to start on my AR pistol...

Selling my Mossberg Shockwave...
These seem to be going for around $320-350 nowadays for the basic model but I can’t really justify that much for what would essentially be a toy. If anyone has used one they want to sell let me know. No Remington version.
