accurate
Precision is a description of random errors, a measure of statistical variability.
Accuracy has two definitions:
More commonly, it is a description of systematic errors, a measure of statistical bias; low accuracy causes a difference between a result and a "true" value. ISO calls this trueness.
Alternatively, ISO defines accuracy as describing a combination of both types of observational error above (random and systematic), so high accuracy requires both high precision and high trueness.In simplest terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be precise if the values are close to each other, while the set can be said to be accurate if their average is close to the true value of the quantity being measured. In the first, more common definition above, the two concepts are independent of each other, so a particular set of data can be said to be either accurate, or precise, or both, or neither.

Les Baer no longer makes new rifles. It was simply too difficult to compete with mass produced, lower cost offerings in the market. Rather than lower their standards, they focused back on their world class custom pistols. Still, this rifle was the first of their AR rifle line, and built with...

I'm consolidating heavily into the 7.62x39 cartridge, and am especially interested in high-accuracy systems. Ruger Mini-thirty owners, is it a contender? Any feedback on reliability is also appreciated.
This ar was built by a small business owner/retired marine in Vancouver. He builds ars up to military spec. I have shot over 1000k rounds through this and it's never jammed. It's very accurate and reliable. I had a tough time deciding if i want to sell this thing but i can't afford it right now...
I have an unfired SP-01 Tactical I’m wanting to get rid of.
