300 Blackout Hunter Carbine (pt. 1)
Whether you’re a fan or not, you must admit the 300 Blackout is a pretty versatile cartridge. From 110 gr supersonic (> 1,100 fps) to a 220 gr subsonic (<1,100 fps), the 300 BLK is suited for both hunting and defensive applications. That’s why just about every rifle and ammo manufacturer is making something for it. Unfortunately, due partly to the manufacturing process, the price of ammo has kept 300Blackout/ Whisper as somewhat of a wildcat. The cartridge in itself consists of a .308 diameter bullet, stuffed into an opened up 5.56 casing packed with pistol powder. It is a short to medium range cartridge. Ballistically, they like to compare it to a 7.62×39. We’ll be covering more on the 300 Blackout in another article, in the meantime there is plenty of info available out there so there’s no need for me to dig deeper into the subject.
Now to give this article a little backstory. About 10 years ago, I became good friends with a dude playing Ghost Recon on Xbox Live. I was living up in Hollywood while he was stationed down in San Diego. Once he was retired from the Navy, he moved back to his home town of San Antonio. So for the past 5 years, before we ourselves moved to Texas, my brother and I had been driving to the midwest to meet up with him and a few other friends for an annual hog hunt.
It was sometime early last year that this buddy of mine asked me to build him a lightweight AR15 good for hunting deer and pig. We discussed different calibers such as .233 rem and 6.8 spc. The .308 win was ruled out because of size, weight and cost. We took into consideration the reliability issues of the 6.8 spc and decided against it. In many states it’s illegal to hunt deer with a .223 rem but in Texas it’s quite popular although shots have to be extremely well placed. That being said, we felt more comfortable with a heavier bullet. What I can tell you is that I have shot plenty of hogs with .223 only to watch them escape through the thick Texas bush. Their skin is like rubber, chest like armor and if you don’t hit them in the right spot… well you get the picture. But lets see those suckers get back up after getting dropped with a 110-125 grain bullet traveling at 2350-2150 fps. Anything within 200 yards is bacon which is why we chose the 300 blk.
Since we got that out of the way, we began the project with a budget of $1500 and plenty of time before hunting season. Because I was going to build it for him, I’d get to use it when I was in town which meant I could leave mine at home. I tried to explain to him the benefits of running a short barrel but he’s as stubborn as a mule and insisted on a carbine since it was going to be used for hunting only. So I put together a few options for each part of the carbine and let my buddy make the final decision. Patiently, I waited for sales and tried to order in as much bulk as possible so we could save on shipping. Here’s what we came up with.
At the core of our project we have the receivers. For the lower, he already had a SunDevil Manufacturing. It was CNC machined from solid billet, many areas reinforced heavier than mil-spec and finished in satin black hard anodized. The tension screw built into the receiver eliminates possible slop between the upper and lower. Simple and clean.
As for the upper, he chose the Battle Arms Development “LW BAD556.” It’s CNC machined from 7075 billet aluminum and hard anodized flat black. As seen in the picture, pockets in the receiver have been made to reduce weight. Pretty sweet looking.
The Rubber City Armory 5.56 “Standard Mass” M16 complete BCG is marked with the Noveske logo. The carrier features 8620 steel with 9310 bolt and tool steel extractor and cam pin. Its Black Nitride finish by H&M Metal Processing increases wear-resistance, fatigue strength, corrosion resistance, and lubricity. This is one attractive looking BCG.
