Prototype Mossberg 590 shockwave pistol grip stock with forend

This is a prototype made out of ABS plastic. I have fired approximately 100 rounds, including a mix of birdshot, 00 buckshot, and low-recoil slugs, and there are no visible cracks in the buffer tube stock.

I have only fired one box (25 rounds) of birdshot using the collapsing stock, and there is no visible damage so far. However, this is still a prototype, so use it at your own risk.

This is also a low-cost way to try out a pistol grip setup on a Mossberg shotgun.

Note: This forend only fits the Shockwave. If you would like one that fits a Mossberg 500 or standard 590, there will be an additional $10 charge.
