Maybe this one will work, but not sure. Looks like you might have to file the right side down at a slight angle to allow it to fit on the mag well edge. I would drop Blaine over at Atlantic a line and email him pics of your setup, but sounds like it may be worth a shot.

That's the same one as the Radlock, and it doesn't work unfortunately :/

Maybe the Prince bullet button will work

Really? Looks like the exact same one HKparts.net has for sale? Says its compatible with MP5. I am no HK expert so I defer to i<3HK.

Good luck.

I have that mag lock on on 5 HK roller weapons, including 2 MP5s from different makers. It does work. The HK mag locks do not fit securely and will fall out if you take your grip off. They also always need filing/dremeling to fit.

What makes you say it does not work?

[Socalmp5]

I have that on my 2 homebuild 9mms, trim to fit and they are held in by lower, are you talking about a metal lower that doesn't have the front pin holes, or the "ears"?

[jeremyro]

It works with the metal lowers too. I have it on my PSG-1 and HK51 with metal lowers.

[Socalmp5]

Some metal lowers don't have the ears..

[jeremyro]

True, I have one of those too. I actually put a little bit of silicon under the BB to hold it in place when I take the lower off. It makes it easier not to loose it.

[tiger222]

of the two the prince is the better one, though trickier to set up.

Go with a grip wrap and skip the bullet button

[offrdmania]

The prince bullet button is 100 times better than the radlock. Its metal, it mounts in the hole; you dont have to worry about it falling off like the plastic crap radlock if your lower doesnt have the front pin hole ears. Ask me how I know lol

No ugly plastic piece to fall off

[jeremyro]

I might have to try that
