Is it possible to keep the ears on your lower with a paddle mag release installed?

Sure it is, I have both a CETME and G3 variant with Navy lowers(clipped and pinned) and paddle mag releases installed.

So I know the polymer lowers are thicker in that area, but that the ears on the metal ones are less meaty. Just wanted to verify that the addition of a paddle mag release to the shelf wouldn't in some way disallow the use of a steel lower with the ears intact due to some sort of constraint in space.

Ears on a factory plastic lower do have to be thinned from the inside. Same with the steel.

And due to the weld on the shelf, sometimes shortened slightly (not enough to notice).

The commercial one is already done.

Here's one I did using the PTR Grip frame.

On this one, I used a standard steel S-E-F and soldered onto it, the ends of the push pin, to look like it went all the way through.

Awesome! On rtg parts there are some that have be clipped and pinned, and it looks like a special cut was made on the inside of the metal lowers to compensate for the shelf, as apposed to just grinding down the entire inner ear stamp formed metal. It appears that they take out just the inner bottom portion of the ear to slide past the shelf.

Yes, I refinished them, and the other Mark soldered the pins in and did the ear machining. I like it more than the old style of soldering in a shelf.

Not necessarily, I have machined about 1000 steel lowers for RTG as well. Total lowers, probably 4000.

Cool! So no need to add the shelf catch to the lower when key cut! Good to know!

So of all the lowers you have gone through, you haven't seen any RA serialized ones? If so, I would love to buy one or all of them!
