2007 Ak Mag Lock

[zippy]

There has been a lot of interest in the attachable/non-detachable mag lock for the AR. The old AK mag lock solution requires ammo to be loaded through the action. This is not desirable with an AK. The ability to remove a 10rd mag (with the use of a tool) to load is desirable and safer.

Here is an idea for a mag lock for the AK. It is a single machined piece of Aluminum that would prevent (block) the mag release lever from being actuated by hand. There is a small slot that can be used with the use of a tool (not a bullet) to release the mag. This part would be attached to the trigger guard with one screw. Unfortunately, there does not appear to be any way of avoiding drilling one small hole in the trigger guard. (see pics)



Another additional option is a modification to the mag latch that creates a receiver with a NON-attachable/NON-detachable mag. The mag could only be attached or detached with a tool in the same way as described above with the addition of a feature on the latch that defeats the spring for attachment.

Granted the new interpretation of the law does not require a non-attachable feature, but may be a less risky option. (see pic)



Should these modifications be attempted? Are there any suggestions? Is there any interest in such a part?

Well, you could eliminate the drilling and just attach it to the roll pin that holds the release lever with a wrap around yes? Basically, just using a drop down square with a bolt and nut to attach the release lever with a slot on the bottom or open in the back for a small jeweler's screwdriver to fit in.


Another option would be to use what I said above with a new solid release lever housing with a slot on the bottom.


I'd use steel as opposed to aluminium, two dissimilar metals tend to corrode with contact over time.

Have a great Kenpo day

Looks Good!

looks good.
i have an idea.

where you have the screw in the trigger guard add a piece of metal then screw from the side to hold it on.

a piece of metal behind the latch and tool hole but before the front of the triggerguard to make sure the lock doesn't move.

The part could be attached to the mag lever rivet. This solution required a fabricated sheet metal part with possibly some welding and fitting along with replacement of rivet.
Therefore, the Aluminum part would be simpler to install and more of a universal fit. (see pics)

One thing to keep an eye out for. I don't recommend configuring a semi automatic centerfire rifle with a magazine well that will actively allow a magazine into the well without retaining it. The fact that you could hold the magazine in isn't good. I'd go with something that requires a tool to remove or think up a way to block the magazine when the magazine is out.

Yep, the second one is right there with what I was talking about. Your CAD fu is good LOL.

Me, I'm just gonna get some sheet metal, then use some tin snips and custom cut and drill. Either Parkerize it or Cold Blue it.

Hey Gene, I'm not getting what you're saying with the hold the magazine in thing. Can't the same argument be made with the Maglocks on the AR styles?

I am a little confused by the response from Hoffmang too. This device would operate just like the AR Bullet Button mag lock except that the tool would have to be something other than a bullet. A mag can not be attached to the receiver unless it is locked in place and the only way to remove the mag is with a tool.

The AK design lends its self to another possibility as well. By modifying the latch, it would be possible to make a receiver that require a tool to attach a mag. Perhaps overkill but less risky.

The sheetmetal version is something a do-it-your-self-er could make. Make sure that the part can not pivot back on the mag release pin, exposing the release lever.

I'm not totaly up to speed on the bullet button but I thought the bullet button requires you to use the bullet to press the button both when removing and while installing a mag. The rifle will not "accept" a mag without the use of a tool so there is never an open magwell condition.

[zippy]

These new locks rely on a new interperation of
"12276.1. (a) (1) A semiautomatic, centerfire rifle that has the capacity to
accept a detachable magazine and any one of the following:..."

It does not say attachable. One does not need a "tool" to attach a mag.

My comment wasn't about the main point of the OP's post, it was about this part:

Another additional option is a modification to the mag latch that creates a receiver with a NON-attachable/NON-detachable mag. The mag could only be attached or detached with a tool in the same way as described above with the addition of a feature on the latch that defeats the spring for attachment.

If you went the way outlined above, you don't want to be able to hold a magazine in the well when in the "non attachable" mode.

The main thrust of the idea should work.

I think you're on to something. That would be a great idea, since I hate having to field strip my AK just to load it.......... Then again, I'd rather be doing it that way, then not have an AK at all

What about just milling/grinding off the tab portion that protrudes below the mag catch mechanism. Grind it past anypoint where you cannot use your fingernail to operate it. Then you have to use some type of tool to push the mag log open to release the mag.

[zippy]

69mach1, I think that is a good idea. You could use a tool with a fork on the end to release the mag.

I am trying for a solution that does not require any modifications to the mag release, trigger guard, etc.. Unfortunately, this makes the parts needed for modification difficult for someone without machine tools.

A prototype will be made and evaluated. Hopefully, it will be relatively inexpensive to produce.

The only problem I can see with that type of design (I like it though) is you would have to put pressure on the back of the mag body with the tool to release it, bending or breaking it. The problem with the Ak is the bottom moves forward into the mag body for release, which means the top moves back. If you grind down the bottom part slightly below the rivet hole you may not get the mag out without damaging the mag. You could drill a hole thru the top of the mag release and inside the trigger guard for a release tool to hook it to pull it back.

It would certainly require the use of a tool LOL.

I'm gonna get some sheet steel, tin snips, file, and drill and see if I can't come up with something reasonable once I build my Romy. It's a simple fix once I have items in hand LOL.
