Hi, local amateur AK enthusiast here.

It appears that we have an a AKS-74U sans folding buttstock with (from front to back):

-ZenitCo DTK-2 muzzle brake
-Zenitco B-11U lower handguard
-Zenitco B-19N upper handguard
-ZenitCo B-18U rail (appears to be the elongated variant)
-BelOMO PK-06 red dot
-Something resembling a Magpul PMAG 40 for an AK (Magpul does have 5.45 AK magazines, however their 40 round magazines are currently only available for the AR-15)
-ZenitCo RK-3 pistol grip

If I'm missing or misidentified anything, please let me know. Thanks.
