When is the right time to use the DMR and the Battle Rifle?

Solution 1:

This depends on a few factors:

• Range
• Your skill
• Enemy's skill

The DMR is more accurate at long-range, but the Battle Rifle is easier to use due to the burst fire.

Chances are if someone is beating you at mid-to-close range with the DMR, they are pretty skilled with it. The single-shot nature of the gun makes it (normally) more difficult to use at close range.

If you find yourself losing often to the DMR at close range, I'd consider switching to it and seeing if you can't master it. Granted, you'll probably see a performance drop for a while, but if you can nail every headshot as fast as you can fire with the DMR, you'll win.

Solution 2:

So far as I've seen, the answer is simply: Always use the BR.

What you mention about range is accurate. On paper the DMR should be slightly better at long range. The thing is, you have to be a really good shot to see the advantage. What the BR gives up in range and damage per shot it makes up for big time with its burst fire. When aimed at the general vicinity of the enemies head, I find I get many more headshots, simply due to the burst pattern.

Solution 3:

For anything other than really long range you want to use the BR. The spread will help with imperfect aim. But at long range the DMR is better if you have good enough aim.
