First impressions are everything, and I am simply blown away by the thoughtfulness and quality of the packaging of my No.80 alone. The muzzle device is a work of art, both figuratively and literally considering the hand-engraved serial and logo on it – details which are absolutely unnecessary but immensely appreciated, as on most high-end products. This is an excellent introductory release. As a collector, I couldn’t be more pleased, and look forward to future product releases / reproduction unobtanium.

The No. 80 that arrived today was clearly machined with precision and immaculately finished. The stellar presentation box and accompanying literature made receiving the device an event, but more importantly, the customer service was second to none. Swift responses to inquiries, timely updates, and even a decisive intervention that quickly resolved an issue with a troublesome courier. Murdoch and Co went above and beyond every step of the way and I cannot recommend their products highly enough. It almost seems a shame to unpack the device and actually mount it to my rifle – almost.
JAMES GORTHY –
Great product. This is a true to spec SA80 / L85 flash suppressor and after an extended web search it’s the only one out there to buy. Plus it is made in the good old USA. My bayonet locks on solid and the vent holes align up properly. I highly recommend it.
