12 reviews Write a Review

Designed to fit 5 & 10 round standard short action AICS Magazines, the ALTUS +2 Base Pad is another innovative and exciting product brought to you by the crew at ALTUS Shooting Solutions. CNC machined from solid billet aluminum, this ALTUS +2 base pad allows you to increase the capacity of your standard AICS style magazines by 2 rounds merely by replacing the stock magazine floorplate. The new 6BR/Dasher version is designed to work with AICS & Accurate Mags that have the Primal Rights 6BR Conversion Kits installed.


  • Increases Magazine Capacity by 2 rounds
  • Easily installs with no specialty tools
  • Securely held in place by (6) recessed set screws
  • Base Pad Profile ensures positive grip and magazine orientation
  • Added weight aids in quick and efficient release of empty magazine for quick magazine changes
  • Precision CNC machined from solid billet aluminum
  • Utilizes existing spring and follower


 * Due to the various bottom metal and chassis designs, we cannot guarantee the fitment of a 5 round AICS magazine w/ +2 base pad in your firearm. (5 round mags w/ ALTUS+2 base pad will not work with Surgeon bottom metal)

    How did we ever do without these...?

    Posted by Max on Mar 1st 2016

    I now have six of the extended base pads. The initial reason for buying one was for the extra capacity. After using one I found the magazine much easier to handle. It offers a more firm grip and insertion is more comfortable and sure handed. This is especially true with cold hands and when wearing gloves. As with all Seekins products I own these are very well made. I couldn't be happier.

    Core +2S Base Pad

    Posted by Dave Ferguson on Feb 9th 2016

    I just received and installed two Core +2S Base Pads on 10 round AICS mags. I am impressed with the weight and quality of the base pad. It tightens to the magazine with 6 screws, no need to worry about a base plate coming loose again. I loaded 12 rounds with ease, not with the usual resistance on the 10th round has when loading the normal 10 rounds. Look forward to shooting with them tomorrow. Very solid product and design - well done!
