In a twist with their usual designs, Slide Fire Solutions came out with a completely different approach to their rapid fire bump fire stock systems in the SSAK47-HYB. Unlike their other models for the AK and AR, which have a very simple appearance, this one is actually made from aluminium and accepts aftermarket or standard issue AR platform telescoping stocks and pistol grips. The design wraps underneath the receiver, replacing the previous grip with a setup to accept AR grips. It still has the famous Slide Fire switch that unlocks the mechanism to place it in a rapid bump fire mode, although the new one has much less sticking out than the previous one. And of course, the AR tube allows the stock to be set at normal locking positions, without hindering operation of the bump fire. It also has a QD mount built into both sides. Overall, I think it addresses some of the concerns with their other products in that they alter the appearance of the firearm substantially and look almost flimsy. MSRP is going for $299.95.

The first video was taken at SHOT 2015, but the product wasn’t ready to be released yet. The second is a simple video from Youtube showing how other aftermarket stock tubes are attached to an AK platform.
