Another Tikka t3x magazine modifcation

[J_Hensley]

I was all excited to try out some of my 75 grain ballistic tip loads in my new Super Varmint. Then I quickly remembered that they are too long for the factory magazine. I was not about to spend hundreds of dollars to solve this problem. Especially since the two extra mags I have only cost me $5/ea.

My methods of cutting apart the magazines went between a small hack saw, an oscillating tool and a red hot X-Acto knife.


I had a piece of aluminum flat stock sitting around so I used that for the new backstop in the magazine. A little bit of hobby epoxy held it in quite well.

Continuing on to the bottom half of the mag, I cut away the bar that keeps the follower in line.

I added to the back of the follower with more epoxy, this time I mixed in some of the plastic shavings, just because.

It’s not pretty, but it works.

I was having feed issues because the follower would not lift the back of the cartridge up high enough. My solution was to install the spring upside down and backwards.
All done.

I’m in the middle of doing the same thing. Only I am molding the new modified mag box and follower. Then pouring new mag box and follower out of a special polyurethane resin. Essentially allowing me to make as many mags as I want. The only problem is needing to steal the leaf springs from existing mags. I might try a mod using a compression spring at the front and back of the follower.

I wish that instead of the flat “Z” springs they used a wire spring. I think it would lift more evenly.

I wonder if an ar15 spring could be modified to fit….probably too big.

I was thinking the same thing. Easy enough for me to check. I’m pretty sure the AR mags are substantially wider.

I think with some modification, a Pmag spring could be made to work.
