The RPK is a 7.62x39mm light machine gun of Soviet design, developed by Mikhail Kalashnikov in the late 1950s, parallel with the AKM assault rifle. It was created as part of a program designed to standardize the small arms inventory where it replaced the 7.62x39mm RPD light machine gun. However, this is the RPKS-74, the paratrooper model of the RPK-74, equipped with a wooden folding stock from the RPKS.
When it comes to replicating AKs into the Airsoft form, LCT are one of the best in the business. This is one of the most accurate looking replicas on the market and doesn't have the same problem as most AK AEGS as their receiver is a centimeter than it should be, where the receiver meets the stock, as it has to make space for the actual gearbox, but a lot of AK AEGs are like that.
The RPKS-74MN is a finely made AEG as it's made out of Aluminium, Steel and Plastic to give its weight, which is around 4.5KG. LCT tried very hard to make the best replicas as there are parts that really show off its RPKS-74 qualities. For instance, the wooden, folding stock is a dead giveaway, the folding bipod and the magazine is a lot slimmer as it holds different caliber bullets (5.56). The airsoft version's magazine holds 600 BBs. That's a LOT of BBs.
When it comes to taking it for a spin, it shoots very well. Around 30 meters from your target, you'd hit it very frequently. The hop up unit is very sensitive so we would suggest using 0.25g BBs to make up for it. The PRKS-74MN is NOT a CQB weapon. It shoots at around 400 fps which is way too high but it's perfect for outdoor skirmishes as a suppressive weapon. There is a reason why the Russians love these AKs and we can definitely see why in the LCT product line.
