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)

    Works perfectly!

    Works perfectly with my accurate mag. I am able to fit 13 dasher cartridges without feeding issues. Just ran this in a match yesterday and it was perfect the entire match. Nice work on the design!

    2 Round Mag Extender

    Posted by Jimmy Fallon on Dec 16th 2020

    I purchased one of these mag extenders for my 6mm BR, and it works excellent with the small bump out to hold up the spacer in my magazine. There are 6 set screws on the mag extender so that it can lock onto the magazine. It isn’t cut at the same angle as the base of the magazine, so it is tipped slightly out of square with the magazine, but for a +2 I don’t think that matters. Got a second one in the mail recently. Great product and customer support.

    Well, I had to return this fine product.

    It did not fit my MDT Poly Magazines for my hawkins DBM. The lips on the magazine base were a touch too thick to accept the finely milled dovetail in the base pad. I'm sad because this, just like ALL Altus products are 100% great.

    Excellent product! It works very well with our 6 Dashers. It also made the AI mag load easier than stock. I highly recommend this product!!

    Solid and perfect fit

    Posted by Bryan Z. on Jul 17th 2018

    I have had this on my 10 round mag for over a year and have been in local PRS matches and one national PRS match. It has held up without any need for retightening, adjusting, etc. so this thing is very well designed and cut to precision spec. It’s buikt like a tank and can take a beating. I run .308 Win and 6 and 6.5 creedmoor cartridges and it fits +2 as advertised. Overall, highly recommend if you want a solid and durable +2

    Excellent Seekins Core +2 flooplate extensions are actually +4 in my 260!

    Posted by David, Edgewood, NM on Apr 19th 2016

    These are a solid product all around with quick shipping from Core. I picked up two of these for my 260 Remington. I installed them on a couple of AICS mags that have some use on them. Both mags will now easily hold 13 rounds of 260 with 14 rounds fitting tightly. Sweet! More stages that can be run without a mag change! They also make for easily identifying how your mag is positioned in the hand as the front of the extensions feel different than the back. Should help speed mag changes. Well worth the $35. Very nice fit & finish.
