One of the most common questions people ask about the .300 Blackout is, if you already have an AR 15 in 5.56, is it a good idea to buy a .300 Blackout upper, or just purchase a complete .300 Blackout rifle?
Whether you should get an upper or a complete rifle in .300 Blackout depends on a few factors. If you’ve gotten really comfortable with your specific AR 15’s handling characteristics, then getting a .300 Blackout upper for it might be a good option.
This allows you to use the same lower receiver and some of the same components, while still giving you the versatility of using both 5.56mm and .300 Blackout cartridges. This also means you spend the minimum dollar amount while having a dual caliber rifle setup.
But there’s always that tiny problem of you having to frequently switch uppers whenever you need to use the one that is currently not installed on the lower. If you’d rather not mess with any of that, then you should look into buying a complete .300 Blackout rifle.
This way, you can be sure that your new rifle is built from the ground up with all its components fitted together specifically for the .300 Blackout cartridge, which can help optimize its performance. You may also find that a complete .300 Blackout rifle offers better accuracy and reliability than an AR15 with a .300 Blackout upper, since it was built specifically for the .300 Blackout.
And if money isn’t a consideration, you’re sure to get a really good .300 Blackout rifle. But if you have no idea what to look for, here’s my list of the 7 BEST .300 Blackout Guns in 2023. Without further ado, let’s begin.

Barrett Firearms Manufacturing is a company based in Murfreesboro, Tennessee. The company is famous for their high powered line of rifles which includes the M107 and M107A1 chambered in .50 BMG. But we’re only interested in their REC7 DI rifle.
The Model REC7 DI is available in both 5.56 and .300 Blackout. If you go to Barrett’s website, you’ll only find the 5.56 variant there. The one we’re interested in, the .300 Blackout variant, isn’t on their website, but as of the making of this topic, Omaha Outdoors has some listed for $1,899 apiece, with manufacturer product number 17176.
The REC7 DI has a high precision barrel with a length of 16 inches and a 1 in 8 twist rate. It uses a direct impingement system, an M LOK mounting system, Barrett’s proprietary three pronged flash hider, and a whole host of aftermarket Magpul accessories such as a set of Magpul back up front and rear iron sights, a Magpul MOE six position adjustable stock, and Magpul grip.
With a lengthened gas system that ensures reliability with or without a suppressor, the REC7 DI can be a real pleasure to shoot. The upper and lower receivers are both machined from 7075 T6 aluminum, and all aluminum parts are Type 3 Class 2 hard coat anodized, then finished with Cerakote for the best aesthetics.
You will also appreciate Barrett’s attention to detail as all human touch points on the rifle were refined using the finest parts, including a custom Radian Raptor ambidextrous charging handle, a Geissele or ALG Defense trigger, and an extended slimline Barrett hand guard with Magpul M LOK accessory mounting slots.

The ASF 20 is available in more than a few different chamberings and has a base price of $2,499. You can configure your very own custom rifle build using JP Enteprises’ Rifle Builder on their website, but you’ll first need to register for an online account and do an email verification.
