Sneak Peek: Circle 10 AK Folding Stock Adapter

Circle 10 AK will be releasing a new folding stock adapter soon that should be plenty interesting to those of us who own AK’s with side folding stock trunnions with the 4.5mm pin (there may be a 5.5mm version available at a later date). The new adapter will allow you to swap out the stock for a collapsible AR-15 style extension that will accept AR style stocks. It will retain the ability to fold though it will not use the latch when folded. The images below shows an early prototype of the adapter while folded. Expect the production units to differ slightly than what is shown.

I recently tried to purchase a similar adapter from an overseas source. The entire experience was a pain in the rear and took forever. When I finally did receive it, it didn’t fit either of my AKs with this style of stock and it the extension was commercial diameter so I didn’t have a stock that would fit. It will be nice to have an adapter like this available from a domestic source.

Stay tuned for release details.

    Go to ACE rifle stocks and get their AK receiver block, then get their side folding mechanism, and then their AR stock adapter… Excellent gear, good pricing.

      That will work for guys with a standard rear trunnion but not for those with side folder trunnions. This is for use with AK100 style folding stocks.

    The beauty about our design is it folds flush against the receiver over the optics rail.
