I added the Rifle Dynamics AK to M4 Stock Adapter to my Arsenal SGL 21.
The stock adapter angles the stock straight off the back of the rifle unlike other adapters and AK stocks which slope down. The cheek weld is very high and is designed for use with an optic. It really forces you to mash your cheek into the stock when looking through the sights.
It requires an AR-15 Buffer Tube, End-Plate, Castle Nut and AR-15 Stock. I chose a Mil-Spec Magpul CTR with Mil-Spec parts. Mil-Spec parts are highly recommended. No permanent modification of the rifle is necessary and it takes about 15 minutes to install (if you’ve done this before on an AR-15). As always, make sure you stake the buffer tube castle nut with the end-plate!

Always good to have spare parts for your weapons.
I’m half tempted to keep it as-is. I like the classic look but I’ve already started with the cut down barrel and the comp. So, I’ve been secretly buying parts while Owen was putting it together.
