LCT has prepared 2 instructional videos on how to install both guides. Thanks to the PK-200 and PK-340 guides, the AR-15 collapsible stocks can be mounted in the vast majority of AK carbine replicas. The PK-200 guide is dedicated to replicas with a fixed stock and only one mounting tail (e.g. AKM).
For replicas with left-side folding stock (AKS-74, AKS-74U, AK-74M and derivatives) you can use the PK340 guide.
The use of any of them allows you to fit basically any telescopic stock dedicated for the AR-15 system.
The fashion for modern and adjustable rifle stocks continues. Only the AKMS users must continue to use the classic solution from the 1950s.
Mounting of the PK-200 on the example of an AIMS replica:

Unfortunately, the PK-340 file provided to us was corrupted and we cannot present it. However, installation is very simple - take out the hinge axle of the stock and replace the factory stock with the supplied guide by putting the axle back in place. The stock is folded to the side by pressing the "old" round button on the replica's receiver. To unfold it from the transport position, you need to push the guide slightly down until it passes the hook on the axle and then rotate it into the extended position.
Modern Cossack stocks modeled after products of the Russian ZentiCo, i.e. the PT-1 and the PT-3 are fitted in the same way and only fit replicas derived from the AKS-74 and the AK-74M.

The PT-1 and PT-3 stocks can also be used in GHK gas-powered replicas.
