This is the SSI 28 round Combo Picklist for AR VR style box fed shotguns.

-Use your 19 round metal magazines.. Magazine not include.

-Add the TOP and BOTTOM SSI extension, plus the 1.5 SSI spring to have a nice super reliable, reloadable plus 9 setup.  

-Smooth slide on design that locks down with two setscrews.  Tools included...

-Uses the SSI Basepad or Factory SGM Tactical, Surefire Basepad.

-Modular design allows for multiple BOTTOM extensions.. As we say, build your dream bannana.

-These extensions have been match tested for months with half loaded drops with no issues, although we have replaced a few extensions due to repeated drops on hard surfaces in dryfire.  We recommend not using them in dry fire.  If you have this issue, send us a picture of the failure and we will send a replacement free of charge.  There are also plans to thicken up the areas effected.

Tested Magazines and shotguns
