Swiss Arms, as of Monday, quoted 4-6 months for delivery. We create and receive a Swiss Arms parts shipment every 2-3 months. Call it 6-9 months, more realistically.
A slight delay or two can easily add a month or two to any international shipment, so 6 months to a year is still a realistic time frame.
If there is another place that could get it sooner I'd be happy to refer you to them, but I don't believe R. Nicholls is importing these lowers (I would imagine they would be under the same timeline as us anyhow).
Apologies for any apparent run around or miscommunication.
