Daniel Defense H2 Buffer, Weighted with 2 tungsten and 1 steel weight to 4. A community to discuss Daniel Defense rifles. 308 Before settling on the Daniel Defense CAR H-Buffer Assembly, I considered a standard carbine buffer and a heavier H2 buffer. 25" carbine buffer for use with AR-15 rifles with carbine receiver extensions. 5, 16's. Daniel defense rifles tend be overgassed a bit, so an H2 might be a good idea. For a 16" V7 like yours, the standard H buffer, H1, and H2 should work, but the H2 might be a little too heavy/powerful- you'll have to test them out and compare. Note: Not compatible with the DD5V1, DD5V2 or Ambush .
