Take a look as this tuned MP5 AEG by Bolster in this video by Patrol Base... "The sneaky counterpart to the Bolster Tuned CM.041 upgraded SMG-5 AEGs has returned and it's better than ever! Enter the CM.041 SD5 SMG-5 Upgraded Edition; a full metal SMG-5 SD5 replica built by the same team behind the ultra-high-end Bolster Armouries AEG series and previous Bolster Tuned AEGs."
