tikka ctr to aics bottom metal

[Mersingert]

which company should I pick and why? looking at grayboe and atlasworx mainly.

If you like the factory stock, contact @Shooter71. He can modify the CTR to take both.

so that it can take both ctr mags and aics?

as far as I know most bottom metals that are ctr-aics work within the factory inlet of the ctr stock.

Correct.

 

[Macintosh]

Correct.

Interested in this, I like the ctr mags but would be nice to have a flush or nearly-flush legal option for states with a mag capacity limit for hunting. Is it something a relatively handy guy can do themselves, and will it work with any aics pattern mag (brand, metal vs polymer, etc)?

No clue.

mdt and magpul polymer magazines will fit in the CTR bottom metal with some trimming on the mag. I haven't got around to trying the modifying the ctr bottom metal to better accommodate the aics metal mags

interesting....could you send a pic of what it takes to do those modifications? Is it a couple minutes with a file?
I really like the CTR mags, have a couple and would hate to lose the ability to use them with a new stock that only ran with aics. The option of running both sounds great.

A few minutes with a file. The MDT poly and magpul magazines can be forced into the ctr magwell unmodified and you'll see the areas that need to be trimmed. There is a youtube video or two with people demonstrating it works with the MDT poly magazine.

Shooter71s modification looks as though it allows metal AICS magazines to work since there should be a relief cut for the locking lug on the magazine to engage. The way AICS and ctr magazines are retained are the opposite if that makes any sense.

factory ctr magwell works with mdt 10 round but not 5 rounds as confirmed by me.

I sent the following to another member in a PM, but it might help others looking to run aics in the factory CTR bottom metal.

The modification is a simple one. the mill cut is to allow room for the pressed catch on the AI mags. if you get the depth correct it also helps keep the mag from going up into the bolt raceway. The other detail is removing the small lip on the back of the latch, to allow greater travel. I’ve only used AI and Accurate mags, not sure about the functionality of others’.

For anyone looking to try this mod, I guinea-pigged it for you. Works for me so far, and it netted me an option for 3-round hunting mags without changing bottom metal--details here: https://www.rokslide.com/forums/thr...al-to-accept-both-tikka-and-aics-mags.277514/

Is this modification some thing you do and if so how can I get my CTR to you to have this done?

@jpirwin24 His website is shaen rifles. looks like he’s not accepting new customers, its why I did it myself with his guidance. He came very highly recommended to me so if you can get in do it!

This is part of the reason I put mine in standard tikka stock with reg bottom and mag.

I have thought about doing that as well. The CTR mags will fail. I have 3 mags and all of them give me fits. In the rain they will go down for sure.I'd trade them all for a stock stock and mags. Other wise I'm going to buy a krg bravo. Or maybe a rok stock when I can. But I the mean time just looking for solutions I can do on my own.

 

[Macintosh]

@jpirwin24 you can try this, but either need to fix your mags or get an aics bottom metal of some sort. I have 3 ctr mags that all feed fine and have for the last couple thousand rounds. One of them didnt feed well, that got fixed. Its easy to do, if you search youtube theres a couple videos showing how to bend the spring so the follower “follows”. Might solve your issue.

I ended up getting a Tikka Roughtech takeoff on here for fairly cheap. The barrel channel is really close to the CTR so minimal sanding of channel to get the barrel free floated. I already had a spare Tikka L mag and I did modify the bolt stop to make this a LA 308. Just so I wouldn't be hindered by the bolt stop. Picked up the bottom plastic at Mountain Tactical and for less than $200, I had a "legal capacity" hunting rifle that is pre-threated and ready for suppressor.
