Made in the usa

We have said since day one, if we can't make it here, we don't make it. What Is "Made in the USA?" It's a label that evokes patriotism, carries an unspoken promise of quality, and has a political undertone of job security for American workers.

All Flaltine Ops products are designed, manufactured, assembled and tested in the USA. We pride ourselves on making the best products in our category using the best materials available. We will not waiver.



In precision shooting there are many factors that affect the ability of a shooter to hit a target with accuracy. One of these factors is cant error. Cant error is the result of not holding the rifle bore axis and the scope axis in a vertical plane.
