Hello everyone! Material is currently in and being cut and machined. Then it's off to anodizing and then to me for hardware, assembly and packaging. Looking like March to late march is the estimated shipping time. If you have not already done so, please email me directly at DeFenderAutoCo at gmail dot com so I can add you to the email wait list notification. When these are in stock I'm just going to send an email blast and open the shopping cart up. Want to make sure none of you miss your chance and get my email when they are ready.

Lots of you wanted more than one; depending on total names on the list will determine if I put a limit on how many each customer can buy.

Emailed you.

Maybe worth asking, will these hold zero for a laser? GG&G's biggest flaw is that they will sag, not only does that look awful, it makes them useless. I'd like to run a VIR II IR laser for night vision shenanigans but it's a moot point if this sags as well.

No idea. I don't own a laser to test it with. I'd say if anyone has experience with an OG surefire adapter and a laser, this is expected to perform the same; meaning if it did not hold zero, this one will not either. The dimensions are essentially the same as the MR09, as the end result is the functional position the adapter puts the light in, but cosmetically it is a different look so that I can produce it as a new design. The only item I cannot change is the profile of the USP rail interface, as it is required for fitment. The rest of the mount was updated to be aesthetically pleasing and to pay tribute to the OG look.

I think the 3pc design, 6000 series aluminum, and the wearing of the locating dowels/sockets make the GG&G sag over time. This MR09 reimagining is 7075, and a 2pc design that seems to be much more rigid without much visible flex. It is also why it is so expensive to produce; it has complex geometry that needs a 7 axis mill to complete which adds cost and then needs to mate perfectly with a separate end cap that also fits the rail precisely. It's a bitch of a part but a damn nice flashlight holder thingy.

Please HK, just make a new mold and add a single rail slot to a 1913 standard. It would still look nearly identical but would bring it into 2024. Also add optic cuts, kthxbye.

I'd advise you to test yours and report back should you choose to invest in this one. I hope it meets standard.

This course of action, while very much requested by every HK Fan & Shooter ever, would probably cause a rift in the time & space continuum. We all wish they would do this, but I guess it provides jobs for people to create frame/rail adapters and provide slide milling for optics on HK's... :LOL:(y)

Wanted to give some of you that emailed me a different look at the CAD model of the part as it seems lasers are a big deal (mini MK23 builds I'm guessing).

The concern you all raised was the drooping of the GG&G mount. This design is a 2 pc vs the GG&G's 3 pc and as such looks like it would be much more rigid. The softer 6061 aluminum that the GG&G is made out of allows the dowels and pins to have a bit of give beyond the tolerance that is required for assembly. The 7075 aluminum the new mount is being made of is much harder and doesn't give as much.

I can't say you won't need to monitor and confirm zero until you feel it is proven, but I'll bet once set and left, it holds pretty damn close.

The part has so many curved surfaces at angles 180 from each other, that this part requires a 7 axis CNC mill to manufacture them. The GG&G being a 3pc can go on a standard mill and get ripped out en mass and on the cheap.

All who have emailed me are on the in stock notification list that will go out from mailchimp once they are on my shopping cart. I'll post here after they are live.

I think the GG&G mounts are fine and a great choice, probably the best that is readily available….but…I have read (and doubted) for years here and elsewhere that they are just as good as the original SF. As you are describing the difficulty presented in cutting yours to duplicate the SF, the material used and design…the SF truly was exceptional.
Cool project!
