(5 out of 5) Great Rifle
by from Dove Creek, Colorado on

I researched this rifle long and hard before I jumped into buying it, and every review I read online was extremely positive about the CDI model and the Windham Weaponry brand in general. I decided to order it and have not been disappointed in the least. The rifle has lived up to the high expectations I developed from the research I did. It has a nice finish, and the Diamondhead flip-ups and rail are solid and tight. I've put only 200-300 rounds through mine so far, mostly American Eagle and some steel cased Tulammo, but the rifle has performed without fail through the little shooting I've done so far. Windham has my vote when it comes to price/ quality value, especially when you factor in the discount from SOS.
