The front ends, Yugo AKs have three air  holes (gaps) which is an easy way to determine a Yugo. The WASR-10 is  a standard fixed  stock, full length version. The Yugo Krink AKS-47U is a SBR (Short Barreled Rifle) an NFA item that requires a background check and a $200 federal tax to shorten the barrel

The receivers side by side. The Yugo Krink is above (left) and is built on a Global Trades (Arsenal USA) AK47 receiver, the  WASR-10 is built on a Romanian AK47 receiver (with no dimples)

The two styles use different pistol grips the Yugo Krink uses it's unique pistol grip, the WASR uses a standard AKM pistol grip. The Yugo Krink has the typical muzzle brake, short barrel, and front sight  ont he gas block. The WASR-10 has the standard length barrel with separate front sight and  gas  block. Krink has no cleaning rod

The two side by side, with the Yugo Krink under folding stock opened and closed

The two side by side again. The Yugo Krink doesn't look much smaller but when held the few inches difference really makes a difference. the Krink is a much better weapon for inside a building, for hallways and doors

Two receivers side by side. Notice the  polished bolt carrier of the Yugo Krink, this is a characteristic of most Yugo AK47s

Another shot of both AKs. While they look mostly similar, they are vastly different in quality and their  prices reflect that. While the WASR costs less than $500, the Yugo Krink SBR will cost closer to $1400 after the federal tax

These two rifles disassemble quite  differently. Krinks have an attached receiver cover with a hinge where the rear sight  block typically is. The WASR-10 disassembles the same as  any AKM

The gas piston and bolt carrier are also modified in a Krink, and the  dust cover is hinged. this example  from Ohio Rapid Fire has an aftermarket safety installed

Some shots of the  sights ont he Yugo Krink. Almost all  Yugo AKs have flip up night  sights, this Krink has a flip up night sight in front and two night sight 'dots' on the rear sight

The unique wood on a Yugoslavian AK with three air holes (gaps). The Global Trades receiver looks great on this US made Yugo Krink
