Maven CRS.1 Riflescope

Maven CRS.1 Riflescope is an all-purpose hunting rifle scope hits all the high points and is sure to earn a reputation as a workhorse that the C Series is known for.

Featuring our award-winning C Series glass.  The second focal plane CRS.1 offers an exceptionally clear, bright, and high contrast image with excellent color fidelity. Due to the popularity of our proprietary RS Series reticle options, we tailor-fit the CRS Series with a unique version of the Simplified Holdover Reticle (SHR) to create the CSHR in 0.25 MOA/click units – making holdovers simple, easy, and quick. With a lightweight 14.18 oz. footprint and a streamlined profile, the CRS.1 covers all the bases for most hunting situations and is our recommended rifle scope for eastern and western big game hunting.

Includes neoprene cover.

Superior low-light performance, tack-sharp edge-to-edge clarity, silky focus, and build quality designed to withstand any situation you find yourself in – the benchmark for all Maven optics. We deliver world-class optics straight to the user and eliminate the middleman and his retail markup. Contact us for more information.

Maven Reviews

Modern optics are a field of science that has progressed in leaps and bounds in the last decade. This has produced equipment so powerful and precise; it has opened our eyes to the world around us in unimaginable ways.

This, in turn, has had an effect on photography, people spotting, bird watching and in particular, the world of the modern shooter. Advances in optics have even outstripped the technical development of the weaponry they are designed for.

There are now numerous companies dedicated to attracting our attention as consumers. This is giving us choices of equipment unheard of in the past. One of the companies that deserve recognition for the quality of their products and, in particular, their affordability is Maven Optics.

In this in-depth Maven Optics Review, we take a good look at the company and seven of their products…

From an idea and a great vision…

Maven Optics Unconditional Lifetime Warranty underpins the company’s commitment to quality, being one of the reasons it was formed. Secondly, the desire of the founders to compete with what were the world’s best optics makers at the time. Thirdly, aim to produce high-quality products at a more affordable price to the consumer.

Maven Optics have succeeded brilliantly in achieving these aims.

Rock solid warranty…

The lifetime warranty’s unconditional commitment provides for the replacement or repair of any part or whole of the equipment. This covers damage if it’s not intentional and any defects in the equipment. The only things it does NOT cover are “loss”, and “cosmetic damage that does not hinder performance.”
