Nice having an adjustable stock

Easily installed adapter for an AR receiver extension buffer tube and associated stock(s). While the gun is sold primarily for home defense, the long tube and bore make it a possible hunter as well, the adapter angle places the stock in the right place with good adjustable LOP. A folding stock adapter may also add to the versatility and compact carry/presentation.

The shockwave addition enhances the performance of an already excellent firearm. The quality is superb and installation is hassle-free. Highly recommended and a must-have upgrade for those looking to install a pistol brace or stock to create a SBR. This review pertains to the 410 model.

Mossberg 500 410 tactical stock Adapter

I used this to put an AR collapsible stock on my sons .410. Works really well as an option for youth shooters. I believe the length of pull is now adjustable down to 10.5. Definitely a quality piece. It would be 5 star if it was aluminum. That being said, I don’t expect to have any issues with the polymer
