in High Tech 114, in Kalashnikov box, under AK74, it says that AK74 features a 'prominent muzzle brake. The muzzle brake was effective but increased muzzle blast (+2 to any Hearing or Vision roll to locate an AK-74 firing in the dark)'
'Effective muzzle brake'. Muzzle break is a synonym for recoil compensator according to wikipedia here.

Does that mean that AK74 comes with free 'Compensator' as it appears in Tactical Shooting 76? The hearing/vision bonuses at least align.
