This CMMG piston rifle is special to me because much of it was designed by my friend Bernie White — the same man who designed the original Desert Eagle pistol. When Bernie designs something, it usually works well because he has a rare degree of understanding of things mechanical. He knows rather than guesses what happens inside the gun. The Desert Eagle as originally designed was a whole pound lighter than the current version and meant to be a carry pistol for hunters. The original chamberings were .357, .44 and .41 Magnum, with .50AE appearing later along with the beefier slide.
The main sight is the illuminated Nightforce 1-4x compact. It can be used with both eyes open at 1-1.5x power and as a conventional scope at higher magnification. I also want all my serious rifles to have backup iron sights, but it’s not possible to co-witness a scope and irons. This rifle has offset Dueck Defense sights that go around the scope on the right (but can be reversed to go on the left also).
Since I hope to suppress all my rifles eventually, having an adjustable gas regulator is a big help in reducing the amount of blowback and eliminating overpressure.
Like most things designed by Bernie, this piston assembly is robust and fairly simple. I am looking forward to getting more rounds through this gun with less cleaning than usual.
