Magwells are designed to allow for faster reloading of the semi-auto by giving you a bigger opening that is flared and beveled to guide the magazine home. Is almost like, if you get close enough the magazine will just find its way in on its own. Most can be easily removed, depending on how they were installed.
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.
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.
