Slide Fire Solutions SSAK-47 XRS Bumpfire Stock

Slide Fire Solutions SSAK-47 XRS Bumpfire StockOver the years I’ve often considered picking up an AK-47 but to be honest, I’ve never bitten the bullet and done so.  One of the reasons for this is that although I’ve shot them a number of times, I’m not much of an AK fan and I definitely am not as well versed with them as I am with the AR platform.  Still, I do have some interest in getting to know the AK a bit more if for no other reason than to be better educated when it comes to the AR vs. AK debates.  There are also a ton of AK related products that I’m sure our readers would be interested in but they are kind of difficult to review if one doesn’t own an AK.  ;)  When the guys at Slide Fire Solutions mentioned they were developing the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock (an AK-47 version of their SSAR-15 stock), I started thinking more seriously about adding one to my rifle line up.  Inevitably, it happened.

So what does the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock do?  It works off the recoil of the firearm and allows everything from the receiver forward to slide back and forth in the stock while keeping your trigger finger stationary.  Keeping the stock and your trigger finger stationary while pushing forward on the forearm will create the “bumping” effect which in turn increases the rate of fire while conforming to all laws which require a separate trigger pull for each round fired.  When used correctly, this stock allows for much greater control of the rifle than any other bumpfire method making it the safest way to achieve rapid fire without purchasing an NFA regulated gun.

The installation of the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock is pretty simple.  I had a good understanding of the concept since I have previously reviewed the SSAR-15 stock and it’s more or less the same.  Remove the original stock and pistol grip, install the interface block, and slide the interface into the new SSAK-47 stock.  This process requires the removal of 3 screws which are then replaced with 2 nut/bolt combinations.  So easy, my Grandmother could probably do it.

How well does the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock work?  Hell if I know.  After the great success we experienced with the AR version, I was very excited and had high hopes/expectations for the AK one.  Unfortunately, my results from this stock differ quite a bit from the previous model.  I’m not going to say it doesn’t work but I will say that between the 3 of us who tried it out, the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock does not function as effortlessly as the SSAR-15.  One thing that I believe would make a significant impact would be the use of a front post grip.  Not only will it keep you from burning your hand as the barrel heats up but it will also allow for better leverage when pushing the front of the gun forward.  The recoil of the AK is vastly different than that of the AR so more pressure appears to be required to keep the “bump” action going.

I’ve taken the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock out on two separate occasions and used it on two different AKs.  The first time I went out with pleary454, a regular reader of this site as well as a lifelong fan of the AK-47.  The stock worked off and on but we discovered a feed issue which may have been caused by a dented top cover.  Because of this, I’ve held off writing this review until I could try the stock on a different AK.  The second time out I invited jetsetterak who won the last Slide Fire giveaway we did.  This time, I installed the SSAK-47 on my brand new AK which has been outfitted with a Tapco AK G2 trigger.  We tried 3 types of ammo in 3 different kinds of magazines, all of which provided the same results.

Mag 1 unloaded perfectly.  From then on, it was hit and miss.  We found an issue with light firing pin strikes while bumpfiring so we decided to lock the stock and test it one shot at a time.  The rifle fired fine doing this so that tends to make me lean towards the stock itself being a contributing factor.  I’ll also reference back to the previous front post comment and suggest that had we used a post grip, we could have controlled the forward pressure better and perhaps that was enough to create the problem.  I’m just throwing this out there but it could be similar to the effect seen when people “limp wrist” a pistol and get FTF.

While proof reading this post I decided to visit Slide Fire’s website and read through their FAQ on the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock.  I found this:

  1. The amount of pressure used to push the gun forward has been the biggest problem in regards to the effective use of Slide Fire™ stock systems. The amount of force needed is far less than most would assume, and only 4-6 lbs. of forward pressure should be needed. This should be just enough to barely pull the trigger, and any extra will counteract the recoil and restrict bolt movement causing miss-feeds or trigger reset failures to occur. There is generally a two magazine learning curve and for some it takes a few tries to get the “touch” right.
  2. Quality ammo is very important to the performance of our stocks. Our design works by using the recoil produced by the firearm. Lower quality ammo with less power cannot produce enough recoil to effectively operate the firearm with our product. The amount recoil given by a 9mm is the lowest amount of recoil generally recommended in order to properly use the Slide Fire™ stock system.
  3. The type of trigger your rifle has also can have an impact on operation of the Slide Fire™ stock system. We have seen consistent issues with triggers designated as “match” style triggers. Two-stage triggers or those designed for a light trigger pull have a tendency to cause problems with light primer strikes and inconsistent trigger resets.

I’ve seen many a video where the Slide Fire Solutions SSAK-47 XRS Bumpfire Stock works just fine, including on Saiga 12 shotguns,  so I’m inclined to think there could be some operator head space issues involved here.  With more practice, I’m comfortable in saying that the stock will most likely perform as it should.  The learning curve is just a bit higher than that of their AR model.  I’m sure one of you AK47 peeps will be more than happy to win this stock and figure it all out.

Special thanks to Patrick and Chris for helping out with this review.

    Does anyone know if it would be possible to mount one of these on an SKS tactical style stock?
