Little has made as big a splash in the AR-15 market as Slide Fire Solution’s recent introduction of the SSAR-15 stock, which enables users to bump-fire their rifles at the extraordinary rate of 400 to 800 rounds per minute—and vary that rate as desired with a bit of practice (see in-depth video of the AR-15 stock here).

Now, the same system is incorporated into a stock for the AK-47. To use, pull the Slide Fire SSAK-47 XRS buttstock firmly into your shoulder, reach your trigger finger through the trigger guard and put the fingertip firmly on the stock’s support pad. Then, gripping the fore-end with your off hand, slide the rifle forward in the stock’s track. The trigger will contact your trigger finger, firing the rifle, and recoil will pull the rifle back and allow the trigger to reset as a fresh cartridge is chambered. Since you are maintaining forward pressure on the handguard, the rifle will again slide forward in the stock, and—bang bang b-b-b-b-b-b-bang!

Don’t believe it? Watch the video. Legal? Sure. Every stock comes with a copy of the BATF approval letter. The stocks are built here in the USA of glass-filled nylon, and are tough enough to pound railroad spikes.

Price is $300, and the stock may be ordered direct at Slidefire.com.
