It’s a 16” mid length DPMS 308 with a 5.1 oz buffer and an orange spring. It shoots great, and very accurate. It has iron sights on it, and I really like it for carrying around the farm in the 4 wheeler. It’s not much heavier than a 556 and works well for being ready for coyotes or varmints around the farm when needed. Great brush gun. I have other rifles with scopes but this one is the one that I carry the most.
