I need help

Especially in swat. I am am beast with the Magnum and Battle Rifle but the DMR is weird. It feels like your spartan is holding the weapon sideways and the scope is huge. The DMR in thja game looks like the plasma rifle in Turok 2 Seeds of Evil and I can’t hell but fire from the hip. If you ever played Turok 2 Seeds of Evil you would understand. To tdis day, I have never been positive with the DMR in swat. My closest was 19/20. It is strange because I am always positive with the Battle Rifle in swat, I never been negative. The Magnum I am positive 85% of the time. I need tips with the DMR.
