In mathematics, the Dirac delta distribution (δ distribution), also known as the unit impulse symbol, is a generalized function or distribution over the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one.The current understanding of the impulse is as a linear functional that maps every continuous function to its value at zero, or as the weak limit of a sequence of bump functions, which are zero over most of the real line, with a tall spike at the origin. Bump functions are thus sometimes called "approximate" or "nascent" delta distributions.
The delta function was introduced by physicist Paul Dirac as a tool for the normalization of state vectors. It also has uses in probability theory and signal processing. As it is (or rather, was) not a true mathematical function, some mathematicians objected to it as nonsense until Laurent Schwartz developed the theory of distributions where it is defined as a linear form acting on bump functions.
The Kronecker delta function, which is usually defined on a discrete domain and takes values 0 and 1, is the discrete analog of the Dirac delta function.
Non MOS model.
100 rounds through it in my ownership. Has suppressor sights, zev mag well.
Comes with case and back straps as well as original sights
Love it, just don’t shoot it.
Looking for $850 obo.

I leave back to the East Coast the 3rd so I only have a couple days left to sell this firearm, approx 2-300 rounds down range on this guy

Grey ghost guns flat trigger kit

This item is in mint condition. I had it on a Glock 17 Gen 3 before but that was sold so I no longer need this. It was not used much at all and looks like new in box. This is the Deltapoint (non-pro). It has limited lifetime warranty from Leupold. It is also waterproof (although not recommended...
Like new in box, less than 100 rounds fired with this. Fits Glock MOS and other handguns/ rifles. The delta point works great on the handguns as you can dial it in so your point of impact is at the very top of triangle. This gives you the option of looking at the whole delta for CQB shooting, or...
Question....I'm looking at "something different" for an AR optic....have run Aimpoint Pros with success, have two, but am building a lighter/simpler/less-is-more mid-length 16" AR and was considering running a Trijicon MRO until I came across the Leupold Delta Point Pro. This rifle...
