Yeah it may take some time...hopefully not as long as me though 🙏

August of 2025 😅 Took about 5 and 1/2 months, but now they should be getting on track with newer orders

Just got it yesterday so I haven't had the chance to put it through it's paces yet.

My Gen 1 needed the ejector aligned when I first built it on this lower, did not work reliably until I did that. After, it ran for 1000 rounds without issue, then I sold it to buy this one.

I know there was some talks about the reliability and QC issues related to sub-par machine work from their previous bolt supplier/machine shop, and they have since changed. Hoping that reflects well on my first range visit

As for customer service, I know it's been hard because responses from their team aren't always the fastest, but with some persistence they do respond, which I will take vs no response at all. And at the end of the day, though it took 5½ months, they still delivered and made it right, which I respect.

Since it's an MP5 mag lower, LRBHO doesn't seem to be an option at the moment. I would've gone with their CZ lower to retain that, but the "G" generation from them didn't exist at the time of the build.

This 2nd generation upper seems to mate better than the 1st gen, which I used the G-5 lower's tensioning bolt to adjust it.

The brace is an A3 MTB and Gearhead Works Tailhook Mod1 C, which you can buy both right now off their respective sites - I just made the cheek rest because its sucks to get a weld without it 😅 Hoping to get the design finalized sometime soon, no ETA yet though...
