The Zero Compromise Optic ZC527 is 387mm (15.24 inches) long, weighs only 1122g, and reaches 35 mil in elevation adjustment and at 20 mil¬ in windage adjustment.
It is in a class of its own!
Among all other optics in this magnification range, a very generous field of view of 7m / 100 meters (21ft/100Yds) results in one of the widest in the industry. Outstanding light transmission and exceptional resolution are just two attributes of the best optical design ever developed, perfectly complementing the very best mechanical properties in the industry.
Our goal is not to just build riflescopes. We strive to build the absolute best riflescopes in the world! We don’t skimp on quality, we simply use the best materials and techniques to create the scope you’ve always dreamed of.
I’ve now attended four of Jim Erwin’s classes, and the quality of training continues to amaze me.
His approach to shooting breaks down the fundamentals and rapidly layers them into a combat art form; his approach to training has the entire class enjoying every minute of it!
Jim takes the time to address every students abilities one on one, and EVERYONE, from novice students to to experienced LEO’s, leaves the class a more competent and capable shooter from Jim’s insight, experience, and coaching.
I’ve been through several “certified” courses. I’ve taken classes at some of the large shooting “academies.” And I have yet to find a course that is more beneficial, or more enjoyable, than those instructed by Jim Erwin.
Made the drive from Reno to Gardnerville to renew my conceal carry permit with Jim Erwin. We don’t have too many former Tier 1 Operators in Northern Nevada, so I jumped at the chance to learn from the best and Jim didn’t disappoint. It was a great class, I learned a lot and I highly recommend Jim and SPI.
Jim’s CCW class is informative, direct, and applicable. There’s no ego involved, he’ll occasionally insert relevant personal experience, but will move on well before it reaches the point of self-aggrandizement all too common in firearms circles. Male or female, new to guns or experienced, Jim breaks down the basic concepts, checks for understanding and only then continues. I wouldn’t go anywhere else.
As a first time CCW applicant I wasn’t quite sure what to expect. The classroom session was informative and in-depth, you will learn a lot and was interactive. The qualification/range time was great, Jim reviewed safety, grip, stance, and requirements. He is a very personable and makes you feel comfortable. I highly recommended this class, I will definitely take additional instruction with Jim.
Never taken any kind of gun safety class before! Jim not only gave accredited vital information, he made the class absolutely fun! Totally 💯 would recommend taking any class again from him! Plan on getting more in depth training on how to effectively use my handgun and feel more comfortable to carry! Thanks again Jim 🤩
