Ordered the 407k alongside the adapter plate this website also sells for the echelon 4.0c. I loved the way the plate eliminates the gaps between the red dot and iron sights. This is my first high quality red dot and I’m loving it so far. Shipping was amazing and I felt more confident ordering from here than Amazon or anywhere else.
The red is awesome but the batteries lasted maybe a hour.
Bought this for the echelon 4.0 and I think it’s worth it. Closes the gap behind the optic and iron sights and makes the mounted red dot look cleaner on the gun.
Ordered the "Holosun AMES 2X PRO Green" from Ferrdom Gorilla, iIt came quickly and well packed. I'd say great srevice. The "Holosun AEMS PRO X2 Green MRS" is a great sight
Tried cleaning red dot, ended up using lens cleaner since this product didnt work.
