Well I finely got over to Jerry's Firearms today and pick up a JFS-AR fixed mag kit in Black. When I got home I installed it In my never ending LIF Special Editoin Lower build. Heres my review and how I did it.

 I layed out all the parts and the included Allen key it didn't come with directoins but it was pretty self-explanatory.

The Magizine retensoin bar

 I Drilling out the exopy and cleaned out the wax I put in my bullet button style fixed mag kit.

 

Attached File  1579.jpeg   211.25KB   14 downloads
 I was able to use a pick tool to unscrew the treaded collor that held it in place. Then removed all the parts

 

Attached File  1596.jpeg   106.24KB   15 downloads
Next i installed the wash

Attached File  1593.jpeg   124.72KB   14 downloads
Then the spring

 

Attached File  1598.jpeg   78.33KB   12 downloads
Then the plug 

 

Attached File  1610.jpeg   59.07KB   13 downloads
 I used my thumb to hold in the plug and turned over the reciever

 

Attached File  1607.jpeg   67.26KB   13 downloads
 I then installed the magizine then the mag retentoin bar and screw{ I put a dab of red lock tite on therefor good mesure}.  If I didnt have to drill out the epoxy this part would have take me about 10 minute 

 

 

Now for the takedown pin. yes that is a rifle stock not realy a fan of the othe type.

Attached File  1600.jpeg   84.33KB   15 downloads
 I popped open the but plate took out the one screw and slide the stock off the tube.

Attached File  1602.jpeg   59.87KB   15 downloads

 Now the detent ball spring is removeable so I took that out {becareful where you put this little fellow}

 

Attached File  20170225_231539.jpg   270.2KB   13 downloads

The detent ball was still engaging the the old pin.

 

Attached File  1566.jpeg   93.05KB   13 downloads

So I used a pick tool the move it back

 

Attached File  1568.jpeg   67.47KB   14 downloads

Slid the new hefty pin in and the back goes the spring

 

Attached File  1600.jpeg   84.33KB   14 downloads

Stock back on 

 

Attached File  1561.jpeg   116.93KB   16 downloads

Then the upper and Bazinga 

Shes all doneski.

 

A really nice kit and very simple to put in. The takedown pin is great, but it does need a little use to losen it up a little other then that and not have instruction this kit is awsome I will be using them on future builds for sure.

My Smith & Wesson AR came with a bullet button that was epoxied and I dug it out cause I was going to go with a Thordson stock but i changed my mind so I  also purchased one last month to replace it. Looks a lot better and was easy to install.

What's the benefit of this kit over any other bullet button type product ?

Besides the oversized takedown pin

One the ease of installation no special tools and there is no questoin that the mag is fixed and when the Safe Act gets amended it is easier to convert back as you not having to drill out a ton of JB weld.

I've purchased two of these kits for two different rifles.  Fit and finish on the parts is excellent and the kit is super easy to install.  One of the AR's I installed in had a tighter tolerance on the takedown pin hole and the anodized coating was binding up in the hole.  Probably off by one or two thou at the most.  Called Jerry's and they sent me a new one the next day that was perfect.

Did you fill the head of the allen bolt with JB Weld?

If you loosen the bolt, can it be used as a regular magazine release

Looks nice and easy to  get the Mag out but maybe a little too easy  out if all you have to do is break open the gun and slide that little doohickey in to release the mag and pop another one in.

No you would need to remove the kit and remove washer.

If you losten the bolt the mag will not stay in the gun.

 

Did you fill the head of the allen bolt with JB Weld?

 No I did not yet. cause you need to use a tool to remove the mag so im still up in the air on that. But i most likely will.
