A must have for an sig mcx k with a tapered barrel. Product only fits one way, and makes it possible to attach muzzle device.

5 MPX Muzzle Device Collar
Posted by Jimmy C on Jul 26th 2025
This is what I was looking for. I purchased one from a different source and it wasn't long enough. It must have been left short in order to add shims to time a muzzle device. The one I got from Midwest Industries was perfect.

Perfect. Shipped fast, arrived on time and fit the gun perfectly. First time doing business with Midwest, but it wont be the last.

5 9mm Taper Collar

Plain and simple statement, was the right fit and size. Not sure why SIG needs to be different with the taper mount. My only other comment is on placing orders for MIDWEST, the fact I place an order and want it shipped somewhere else shouldn’t cause me to have to explain.
