Love everything but the stock! 😅 Really wanna build ine of these with a BCA side charger. But BCA JUST cam out with a bolt action upper so 😅. Please do some more videos on this !
@@TheBlackTrapper thanks for the feedback! Ya, that stock doesn't look fancy... but I designed it to be the lightest fully functional stock at just 3oz. It's lighter than anything else on the market. The next closest would be the Farrowtech stock, if you cut up a milspec buffertube and replace all but the threaded end piece with a piece of carbon fiber tube. A friend of mine made one, and it came in at 3.2oz. At 3oz, the stock I designed has velcro for adding or subtracting a higher cheek riser, and an insert for getting shorter or longer length of pull. It also has enough of a shape to the bottom that it works well with a rear bag.
@@TheBlackTrapper it will be interesting to compare the solo300 side charging upper with what BCA came up with. From the pics I've seen, I think the weight of the solo300 will be hard to beat (with his aluminum Bolt Carrier) unless one builds their own with a magnesium or polymer upper.
Ordinary plastics are lighter than "carbon fiber." Carbon fiber / epoxy resin composite material usually has a density of around 1.6 g/cm3. On the other hand, Nylon 66 has a density of around 1.14 g/cm3, and around 1.05 g/cm3 for ABS. And if you want the ultimate in lightness for the pistol grip and hand guard, go with wood. Seasoned walnut for example, has a density of around 0.65 g/cm3.
@@MaximRecoil interesting information. The CF handguard you see on the rifle weighs 1oz, and has a 1mm thick wall. The CF pistol grip on the rifle weighs .97oz. The next lightest pistol grip I am aware of (that is not carbon fiber) is the 15 degree grip from Hogue. It is a bit over 1.5oz. If you are aware of lighter-weight alternatives with a similar strength to weight ratio, please add them to the comments below. Thanks!
@@ultralightoutdoors You probably won't find anything off-the-shelf that's lighter than what you already have, because companies making, e.g., a plastic AR-15 pistol grip, wouldn't be aiming to make it as light as possible. There are plastics strong enough to do it though (for example, Glock frames are made of some flavor of Nylon 6 or Nylon 66). So short of having something custom made you're probably about as light as you can get on those parts already. However, you _might_ save a little weight by going with an original style lower receiver, i.e., one like the early M16s and the Colt AR-15 SP1 used. Those don't have that "fence" around the magazine release button and the section in the rear that the butt stock attaches to has less material in it (that section was beefed up starting with the M16A2 to reduce the chance of it breaking there). There's at least one company that makes a reproduction of those for about $160 (search for 601 Slickside Lower Receiver). They are normally used for retro AR-15 builds. You could contact them to find out how much they weigh.
@@MaximRecoil thanks for the info. I believe the retro aluminum slickside lowers are around 8oz. There are a few polymer lowers out there, New Frontier makes one at about 4.2oz. The CF one I used in the video is a hair over 4.0oz. Here is the walnut version of the exact grip I use in the video... note it is 2.3oz, not the .97oz of the carbon fiber version. mdttac.com/mdt-pistol-grip-wood/
@DrewEdwardBacklas the upper is from solo300.com, the handguard I made from carbon fiber tube off of Amazon. Tight fit over a JAG composites barrel nut (with a bit of sanding).

Any chance of a parts list? I’m curious about where you got the upper receiver and the handguard. Or did you make them?
