This is the SSI 25 round Combo Picklist for AR VR style box fed shotguns.

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

-Add this extension and SSI spring to have a nice super reliable plus 6 setup.  Using the factory spring or SSI replacement. -19 round mags become reloadable 25 round mag.

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

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

-These are NOT modular extensions.  Although a Vepr SSI extension will fit on the bottom, the AR VR Follower will not pass through it.  

-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

AR: VR60, VR60plus, VR80, VRBP100, VRPA40, Typhoon
