DIY Extended Mag Release
I was about to throw down my hard earned bucks on a $16 mag release when I realized that since birth I had this gift where I could pretty much MacGyver the hell out of anything mechanical. So... I decided to have at her and now you can too.
STEP 1 Gather up some supplies.
You will need your factory mag release, a piece of aluminum angle about 1/16" thick and cut to 7/16" wide, a 6-32 countersunk screw, a tap and the required drill bit, locktite, JB weld, epoxy and some black paint.
Step 2 Align and drill through both your pieces, use the tap on the factory mag release. Bore out the hole on the aluminum angle and countersink it where the head will go. Screw both pieces together tightly keeping them aligned and make sure you use locktite.
Step 3 Rough up the components with sandpaper and JB weld everything, especially the seams. After the JB weld cures, sand it smooth and even everything out so the components start looking like one seamless part. I used a dremel with a smooth sanding stone to do all this. Regular sandpaper will take too much off. Test fit the part before proceeding.
Step 4 Now that you have your desired shape its time to dip it in epoxy, this will further give it more volume and make it seem like one seamless part. The best stuff to use would be tooling epoxy but just about any off the shelf epoxy will do. Let this cure over night.
Step 5 With the epoxy set, now you can sand it smooth and dip the part in paint or spray paint it. Make sure you test fit the part again and check operation of the mag release before painting.
Couple Notes:
For operation with the factory rotary magazine you will need to trim off the thumb tab on the magazine itself or else this will wedge up against it when you're trying to take your mag off. I did this to mine with a dremel and now the magazine just falls out when I push on the mag release. It works great!
Another thing to note is that if you have to go out and buy all the supplies then you might as well buy the darn part to begin with since it will cost you less. I did this because I already had all this stuff at home.
Well there ya have it ladies and gents. Have fun and play safe.
