What was delivered was not what I ordered. A receiver with a buffer tube spigot on the lower receiver was what I ordered. What was delivered was a lower receiver with a threaded aperture. I have a lathe so I was able to machine an adapter.
This does not fit my mws urgi, holes won’t line up.
Awesome had 2 orders from 6mm, very happy. Be patient with delivery 👍
Good product, easy to load. Awesome perfomance.
The parts quality of the silencer itself are nice but the thread for the QD-mount is off center and uneven.
When used on a replica the silencer is crooked.
I will attempt to bend the thread with a Industrial heater, otherwise it is useless.
