Most AR-15 stocks sold today are adjustable and have a few different configurations for mounting slings. Some even have storage compartments for batteries or other items. DOUBLESTAR<\/a>\u2019s ARFX-E AR-15 Skeleton stock, however, does none of these, and yet is an option you may want to consider. The tubular-looking stock is easy to install and only had one thing about it I didn\u2019t like.<\/p>\n

With AR-15 rifles, there are so many options for configurations that it\u2019s cool and annoying at the same time. I\u2019ve spent more time than I want to admit looking at stocks, pistol grips, handguards, and other parts. Looking for that special part that stands out to you, can turn into a long search. And when you do see one that looks like a potential fit for you, there\u2019s always that question about quality. Is it worth the money? Will it hold up over time?<\/p>\n

While I like adjustable stocks, I also like the idea of a solid stock that won\u2019t move or rattle. I also wanted a fixed stock that was shorter than a standard A2 stock. The DOUBLESTAR checked both of those boxes.<\/p>\n

Installing the ARFX-E<\/h2>\n

Instillation on the ARFX-E skeleton stock is easy except for one part, which I will get to shortly. It uses a standard carbine buffer spring (the same as the adjustable stocks) so there are no additional parts to buy. If you had an A2 stock\/tube with a rifle-length spring, you may also need to switch out the buffer weight. Rifle-length tubes often use a 5.2 oz weight and carbine tubes a 3 oz. Standard adjustable stocks use carbine tubes, so if that is what you are replacing, you should be good.<\/p>\n

\"Doublestar

Once the castle nut is unscrewed to the rear, pull the back plate to the rear as well. Take out the small rear takedown detent spring so it doesn\u2019t get lost. Now, unscrew the buffer tube while keeping your thumb over the buffer tube retention pin. When the tube is off, you will be ready to install the new tube (see photo above). Use the square notch on the back to tighten it with an armorer\u2019s wrench.<\/p>\n

DOUBLESTAR includes a foam pad that slides over the buffer tube at the same time as the frame of the stock. You are supposed to place the front of the stock over the buffer tube, then add the foam pad and slide them both onto the buffer tube at the same time. That little takedown detent spring should also be put back on before you start this process (see photo below). The foam pad is where I ran into trouble.<\/p>\n

\"Installing

Installation failure?<\/h2>\n

According to the instructions, you can use an air hose to blow air under the foam pad to help it slide more easily. This didn\u2019t work for me. The foam pad has a rubber-like backing to it that sticks to the metal tube like glue. I\u2019m sure this is great for keeping it in place once installed, but I couldn\u2019t get it installed. I will admit, this could easily be my error and not that of the product. I tried everything I could to slide the foam pad over the buffer tube but eventually, I pulled, and it ripped.<\/p>\n

I\u2019m not sure if there was a seam or how I managed to do it, but it ripped from one end to the other. I finished installing the stock by sliding it over the tube without the foam pad. When it\u2019s pressed against the back of the lower receiver, a screw goes into the back of the tube to secure it. This should be the end of the process, but now I had a metal stock with no foam pad. I thought about gluing it on but who knows if that would hold up.<\/p>\n

\"Foam

[Photo: Jason Mosher]<\/figcaption><\/figure>Instead, I turned to my go-to fix-it tape (aka Duct Tape) and decided to just wrap it in black. Of course, this doesn\u2019t look anywhere close to how it should look. I like the foam pad and metal look, but again, mine wasn\u2019t about to go on. I\u2019m wondering if the humidity made it worse. Anyway, I placed the foam over the tube with the seam at the bottom and wrapped it in black Duct Tape. I e-mailed the company about the issue, and they promptly sent out two replacement foam pads within a few days. This was great customer service!<\/p>\n

Is a fixed stock right for you?<\/h2>\n

A fixed stock like this one may not work for everyone. I have longer arms, but it\u2019s still comfortable for me to use. At some point, I plan to add a side folding adaptor like the Sylvan Arms<\/a> Folding Adaptor. Stern Defense also makes a Rab-Ad adaptor that lets the stock come completely off the rifle. Either of these adapters would add just a little bit of length to the stock. This would add some length to the stock if it’s too short for you. An adaptor also helps with storage because you can fold the stock to the side or remove it.<\/p>\n
