Mag-Lock with Original Hardware.

[NoTime2Shoot]

I saw this in another thread. I thought my reply would be better suited here. Flamesuit, on.......

The vendor did have an awesome new mag locking device. It utilized a standard push button release, but had an allen screw in it, near the standard threads, to lock the button, but with a turn of a allen wrench, backing out the screw returned the button to normal free-state function. if I do another build I will use his mag-locking device.

*Disclaimer* - I have never built an AR. Although I am a machinist, If you attempt any of this, it is at your own risk!

I actually thought this out last night! I was ordering parts and figguring how I wanted to build the lower.

I am going to attempt to fix the mag, using the stock mag parts and an allen nut. In order to accomplish that, I am going to start by fixing the button on my mill's vice. Using an endmill, I will open up the mag release button hole, large enough to be able to accept a nut.

In order to have a nut that fits, I will have to trim down a nut. Here Is what I thought of to hold the nut on.



I will make the tooling bar out of a drop piece of chrome rod. Lathe drilled and tap'd for a #10-32 stud.



The nut Is tightened down against the spacer and cut with a single point cutting tool. The spacer is sacrificial, it is just for some tool releif. It could even be an extra nut.

I also stumbed onto some really cool anti walk trigger pins.

The price is great, but if I'm going to take time to make a nut tool I might as well make the pins. The pins are 0.154" in diameter. A 5/32" round is 0.15625" in diameter. It wont take much to polish them down. I can lathe drill enough to bottom tap the holes for #4-40 button head allen screws.

Anyway. Thats what I'm going to try. Heres the "before" picture. I'll post more as the parts come in.

Those anti walk pins are a silly price. jeeze. If you want to make a few extra, I'd be willing to throw down a few $. Let me know what you think they'd cost.

Other than on the Fulton Armory website, that is the only Fulton lower I have seen!
I have one myself, but the DOJ is holding it for me so I have not seen it yet.....

Send lawyers, guns and money... The DOJ has hit the fan!




Jeff,
Thanks for the photo link.

At least we don't have to hide in Honduras.

No problem.

You mean like this one:

I am interested in to see how you plan one implementing your idea (in the opening post).

I don't want to steal your thread, and I haven't seen the mag lock discussed, but it sounds like you are going to go through a lot of work. I plan on doing the following: get a few standard mag release buttons, drill a hole in each parallel with the existing hole, offset to one side, thread the new hole, get some straight hex head screws (the kind without the flared head) the right size that will sit flush when tighened. Maybe shorten the screws if needed so they sit flush.

I need to drag out my drill press and tap and die, but I figure it'll take maybe 5 minutes each.

It sounds like a lot of trouble. However, my machines are already tooled to do the work, so it should be fairly quick. Really, $45 bucks is about a half hour of shop time. So, it really is about a wash for the pins, (except I plan on being on the lathe anyway).

I fixed the link for the nut jig above.
