Anschutz 1727 magazine basepads

I have not found one

I bought a couple of these. Wound up having to buy two Savage mags to rob the springs and followers. Then there is some minor fitting to the follower.
Do they work? So-so at best with a full 12 rounds. If you have never owned an Anschutz then be advised that the magazines are not perfect. Mine run great 99.5% of the time but you must take care not to get "rim-lock" when loading them. In fact, in the downloadable manual it has a section devoted to loading them.
I wish, even with what seems to be some issues, L3i would come up with a plus rounds mag for the Annie.

With some attention to detail, and careful assembly they work perfectly. You have to modify the savage follower. Great 12 round magazines.

So do I have to buy Savage magazines and steal the followers out of them?
Magazine Extenstion for Anschutz 1420-U13 Magazines

****Requires custom fitting of CZ or Savage follower and spring!****

Design Features:

  • Adds at least +2 capacity (loading past 12 may reduce reliability)
  • Developed with input from US Precision Rifle National Team members
  • Access ports at front and back of extension to make sure spring is seated properly
  • Requires use of follower and spring from CZ 455 10 round poly mag (#12004) or Savage mk2 10 round mag (#20005) - either follower will require bending (CZ) or trimming (Savage) to tune the fit for proper function. Followers and springs are not included.
  • Includes extension and M3 set screw only
Install Instructions:
  • Tune follower as needed to fit magazine body
  • Install follower and spring in body
  • Compress spring to allow extension to slide on from the front
  • Slide on extension
  • Ensure spring is seated against floor of extension - use holes at front and back of extension to manipulate spring as needed.
  • Back out set screw using 1.5mm hex wrench (not included) until 2-3 threads are above rear of magazine to lock it into place.
I used Savage magazines, remove minimum material from the follower. It must travel without binding (at all) the length of the magazine body. Good Luck

You are awesome!
I saw where someone had modified Savage magazines to fit and feed in an Anschutz by doing some creative fitting. To me I would rather spend the $$ on Anschutz magazines. When I bought Savage mags to rob parts necessary use these extensions a quick check of a couple places on the internet showed quite a difference in cost. Got mine from Midway for about $20 each. The extensions will also work with CZ mag spring and modified followers.
