Review: Strike Industries Viper Stock

Last year I had the opportunity to review Strike Industries’ Viper hand guards and really found them to be a solid value for the money. Now that the Viper stock from Strike is shipping, I was given the chance to review the matching stock. Now to be fair I have become a bit of a sucker for Strike Industries’ product line, there is just something about a company that provides a quality product at a reasonable price makes me gravitate towards their parts.

The folks over at Strike sent me a Viper stock in black and flat dark earth for review, when they arrived on my doorstep if found two stocks that were exactly as I would expect from Strike. From a quick go over the Viper seems to be a wonderful value if you are looking for a stock in the sub $50 range.IMG_1301

The stock’s aesthetics are a perfect match for the Viper hand guards from Strike that I previously mentioned. When I am not testing products I normally run a good sling on my rifles so the QD port that SI included as well as provisions for threading a sling directly into the stock is something I really appreciate. While the stock does not have some sort of lock the latch did provide a reasonably tight lockup in whatever position I chose. If you compare the Viper stock to the Magpul MOE stock another $10 buys you a QD port and a slightly nicer overall finish, not a bad trade off. The only downside I found was that the Viper stock will only work on Mil-Spec buffer tubes, maybe Strike will rectify that in the future with a commercial version of the stock. IMG_1303IMG_1941

The Mega Fins free float hand guard works well with the Viper stock, but as much as I can appreciate aesthetics, how the stock feels when shooting is the important part.


My friend Bryan got the chance to take some shots with the rifle with the Viper stock equipped and liked it quite a lot. If you have facial hair like Bryan or myself you are probably well aware that some stocks will trap your facial hair between the stock and buffer tube. While I am sure it is possible on the Viper neither one of us experienced any discomfort, the extra 1/2″ of length on the Viper may have something to do with that.      IMG_1434Stock

After spending a few days at the range with the Viper stock I have to say I am rather pleased with the stock. Features like the large latch, the QD port, and the extra length make it a solid option if you have a mil-spec buffer tube and are looking for a upgrade around the $50 range.

You can learn more about the Viper stock on the Strike Industries web site by clicking here. The MSRP of the Viper stock as tested is $49.95 for the version with the black QD mount and $50.95 for the Redline stock with a red QD mount.

    I still don’t understand why we have commerical and mil spec buffer tubes.

    • Patrick R.

      The best that I have been able to figure is that DPMS figured out they could save some money many years ago by altering the buffer tube.

      California. AWB. Other nonsense.

    • Khezquiyahu Yisrael

      1994 AWB, so we couldn’t use collapsible stocks, ended in 2004, industry kept it alive building new stocks, for post ban rifles

      • Cymond

        How does that make any sense?
        We’re discussing ‘commercial’ diameter collapsible stock tubes.

        • Khezquiyahu Yisrael

          Colt changed both the pin hole and stock tube dimensions for cilviian rifle during the ban. The industry followed and never dropped commercial size tubes to appease the post ban owners. Checkout out my blog, Khezcorner.Blogspot.Com

    The one I got was a little less than “solid”.

    • politicsbyothermeans

      Curious how/when that happened? Is that just from normal use or…?

      • GearHeadTony

        (Full disclosure) I had a round stuck in the chamber due to an issue with a fresh upper build. I mortared the rifle with this stock against a wooden table *crack*. I swapped the stock out for a spare plastic “M4 style” stock that I had laying around. 2 more mortars on the cement and the stuck round is out and the M4 stock is still going strong.

        • politicsbyothermeans

          Awesome, thanks for the background. If a piece of kit fails to survive a legit expedient stoppage reduction method that is valuable info. I suppose at that price point it’s not much of a surprise but it really should have survived a whack against a wooden table.

    • Patrick R.

      Woah! I will admit, I did not mortar my rifle when testing the stock. Have you emailed Strike about the stock breaking?

      • GearHeadTony

        Sent an email two weeks ago, never got a response. Disappointing, because it looked cool and felt good when shouldered.

        • Patrick R.

          I sent a message to someone at the company, hopefully they reach out soon.

          • GearHeadTony

            [Update] I have been in contact with Strike and they are sending me a new updated version of the stock. They’re a little slow to respond to emails but they are very nice and are taking care of the issue for me.

          • Patrick R.

            I am really glad to hear that they took care of it.

    • Strike Industries

      Sorry we didnt get the email. You can email and we’ll take care of you immediately. Let us know when you ordered the stock and where you ordered it from in the email. The thing is without the rubber pad, which is almost ready, and hard surface mortaring its likely you could cause this to happen on the early batches of stocks. There has been improvements made since directly due to this and we would be more than happy to replace it with a new one for you if you contact our support team. Perhaps you could be one of the first to test out the new rubber pad for it when ready too! Thanks!

    • Matthew Whittington

      Did you get it resolved Tony?

      • GearHeadTony

        I emailed them Friday the 6th and haven’t gotten a response yet. Hopefully just because it’s a weekend. I’ll repost as soon as I get a response.

    Looks vaguely like a Mission First minimalist.

    • TennTexan

      Having used both on my 9mm SBR, I’m going to be switching back to the Minimalist. The Viper rattles around on the buffer tube too much for my liking. Plus the butt end is just hard plastic, rather than a nice rubber pad like the Minimalist.

      • ozzallos .

        I love that rubber pad too. Mission First makes a lot of good stuff. Magpul Tier if there is such a classification.

  • Redfoot

    I really like mine, but I have in fact moved to a Magpul MOE carbine fixed stock for $18. Seriously, if you guys use the stock about 3 clicks out, give it a shot. The Strike will find a home on another lower though, I really like it. BTW, I have split at least 2 “OEM” stocks mortaring in the last 10 years.

    • Ergo

      i really like the fixed moe. I have a few. I’m thinking of putting a h6 in a lower with one just so i can run a 20inch upper on it.

    Also, another importance in difference between milspec and commercial is. Milspec tube uses 7075 aluminum and commercial is made from 6061. 7075 is roughly twice as strong of 6061 aluminum. Then add in the manufacturing process. And a milspec buffer tube is significantly strong over a commercial tube. Using a commercial tube is just one of several manners to keep cost down. Some companies are crafty in their market scheme, by saying the buffer tube is milspec in diameter. However, the rest of the tube is by commercial specs.

    • Ergo

      for even more fun don’t forget the milspec diameter commercial tubes made of 6061

    The SI Viper stocks are like the hollow-cored Magpul stocks except that the heels are more streamlined in profile.
