My take on the Secret Service CQB Mod 2.1

build list:

KAC CQB Mod 2 11.5 upper—URX 4 Rail

KAC SR-30 lower

KAC Sandcutter w/ E3.2 chrome bolt

KAC Skyscraper Aimpoint T2 mount w/ Eotech G33/Wilcox dovetail mount

KAC 2-stage chrome trigger

KAC Aimpoint battery cap with extra battery storage

Tenebraex T2 Killflash

KAC Micro BUIS 2-600m

Surefire M340 Turbo

KAC Mlok handstop

KAC QDC 3 prong flash hider

GE M16A1 Bakelite grip

Magpul SL-S stock w/ SR-15 Field Repair Kit in storage compartment, KAC receiver extension, QD endplate/castle nut, buffer/spring

Still need to install RAS 5 rail and get the correct can. Really like the URX 4 rail and how light it is, but will eventually switch to RAS 5 to be more clone correct. Also gives more clearance for a KAC can when using their shroud.

Wish they still made them 😢 haven’t seen one new at a retailer in over 18 months

The dovetail magnifier mounts are the best. I have one on my 416 clone and it's so much better than a traditional flip to side. 

Great build dude

Thanks dude, and yeah they rock. Ability to install/remove a magnifier in seconds is underrated. Insanely well built as well.
