This DPMS A-15 is a great option for a Designated Marksman Rifle, having a 20” barrel and a bipod already attached. Being a little heavier of a setup, the felt recoil will be minimal allowing for faster and more precise follow up shots. Having the 20” barrel, this rifle will allow for full powder burn of 5.56, giving better velocity and accuracy. Over all this rifle is in good shape with few signs of wear.
