Well I got my MP5-f kit and my LSC flat and I am looking at this lower shelf I have to add and it seem to go right where the pin for the paddle mag release is.. So i am wondering how you guys have been doing it on your builds any pix would be great I have been using the search feature but still a little foggy on this first time build for me Thanks

Locate dead center of each hole for the mach-catch. Go down 0.6150" and drill a 1/8" hole on each side (but absolutely no larger than 1/8"). Once the flat is rolled, you will need a custom-made bushing for the paddle. Install the paddle using the bushing and 1/8" O.D. rod. TIG weld the ends of the rod to the receiver and grind smooth. Then mount your shelf.

Interesting... I would have done the install AFTER the shelf was mounted. Thanx for the idea.

When I added a paddle to my G3 and G3K conversions, I hated drilling through the shelf cause it was a PIA to take your time cleaning it up so the shelf didn't look fugly.

Chopstix is right, although I have not done a flat, I have done several paddle mag release conversions over the years. Doing it BEFORE you install the shelf, is the only way to go. You will end up with a very nicely hidden job.
Good luck with it...

You're welcome!

NOTE: If you make the bushing yourself, you will need to machine in (or use two washers) for each side as the paddle is narrrower than the space it sits in. If you do not, the paddle will slide side-to-side and bind up. For reference, the bushing needs to be 0.610" long and the working area for the paddle needs to be 0.480" long. If you make the working area any shorter, you also run the risk of binding the paddle.
