CONFIG A "Reaver" This DRG-1N is designed to be fast (~101km/h) Raider able to harass and take some punishment. CONFIG B "Reaver II" Config B drops the larger XL engine in favor of an XL-300 which drops the speed down to ~90km/h. However this config has a higher armour rating, an AMS and houses 2 MPLs in favor of the 2 MLs currently equipped. The AMS and 1 ton ammo can be dropped for an extra 1.5 tons of armour given that AMS is now longer as necessary due to the LRM nerf.
Well aren't you just a Mr. Scrooge there, Michael...just messin' This is probably my favorite Dragon chassis, because the 2 missile slots let you use 2xSRM4 instead of 1xSRM6, which is a significantly better SRM platform. The Reaver II build is actually pretty similar to my 1N. I swap out the AC/2s for a single UAC/5, 1 ton of AC ammo for 1 ton of SRM ammo, and got armor to near max. I'd probably drop AMS and pick up another DHS or ton of ammo now, though. Overall, solid build, and I bet you kill a lot with it.
