111 338 extended mags

[Kyle11]

Hello if a thread is already out there could someone help me find it? My search did not bring up what I’m looking for.

To keep it short: 111 338 win mag bottom bolt release and I’m trying to gain clip capacity. I haven’t seen any mags allowing me to do this. I have a Boyd’s stock on the way, and did not order the “bottom metal” they offer

These fit the factory bottom metal and are great.

Shoot I didn’t see the option with the plastic tang release. Thanks! If these are tricky to come by(out of stock) has anyone modified a factory flush mag by adding a longer box below and used a longer spring?
