A while back I built the Zvezda 1/72 Mi-24 Hind. I got the opportunity to do this review and grabbed it, as I wouldn’t have to build the entire kit just to add the nose guns
The package contains two guns. The kit gives options of two different guns in the nose turret. The one I used is the Yak-B 4 barrel Gatling-type gun, 12.7 mm. The other is a twin-barrel gun the G-Sh-30, a 30 mm weapon. The 12.7mm has been phased out, and the 30 mm is preferred, as it has more punch, particularly on light armored targets.
The G-Sh-30 is definitely superior to the kit parts, as the kit gun comes in 2 parts, so you have to deal with a seam. The QB part has slightly finer detail, which is still hard to see in 1/72.
The Yak-B looked quite a bit like the kit part, and fit into the turret nicely. The only outstanding difference was that the hump on the kit part is a recess on the resin part.
