   Modify an M4A1 to comply with the given specifications

   Colt M4A1 5.56x45 assault rifle

   How it has to end up

   Build it in the builder

   • Ergonomics ≥ 40
   • Recoil ≤ 280
   • Durability ≥ 60
   • Magazine ≥ 60
   • Weight ≤ 5 kg

   With these parts on it

   • AR-15 Alexander Arms MK10 rifle length handguard
   • KAC QDSS NT4 5.56x45 sound suppressor (FDE)

   Recoil is the sum of vertical and horizontal, which is how the quest measures it. The builder shows vertical only.
