Checkout this .300BLK AR Pistol, yes pistol. But, it’s not an AR pistol with a short-barreled and a brace instead of a buttstock. This custom made gun can actually be shot and carried like a handgun.
Elijah Duray of Eagan, Minnesota is the builder of this almost look a like Han Solo blaster. His .300 Blackout pistol on an AR-15 platform weighs about 38 ounces, which is about the same as a 1911 pistol.

Elijah saids he built this as a side project with the hunter in mind, but a little different. But, I think this would make a fantastic survival gun. When you look at it you’ll notice there isn’t any buffer tube. The gun is not a semi-auto, but a straight-pull bolt action with a side-mounting charging handle acting as the bolt handle. Yes, its a manual.

This Blackout doesn’t need a large gas system. Every time you pull the bolt back, it cams, ejects a round, and chambers a new one. Elijah built this gun this way so as to trim as much weight as possible.
“You don’t need a gas block, a gas tube, you don’t need a hand guard, you don’t need a normal charging handle, you only need half a bolt carrier you don’t need most of your gas key, you don’t need your bolt catch, your buffer tube, your buffer, your spring, all these part that you can eliminate by making it a straight-pull bolt action pistol,” says Elijah.

Running Quiet
Another cool thing about Elijah .300 Blackout AR pistol is that you can run it suppressed. Elijah wanted this gun to also be more quiet than the regular AR pistol.
Because this gun don’t have to have enough pressure to cycle the action you can load subsonic in any weight that you want. The result is that it is very quiet when suppressed.
Another piece to eliminating the action noise while trimming weight and parts, this AR frame uses a hybrid polymer lower and upper (with metal inserts) and is manually-operated.
Without the need for a Bolt Carrier Group he says he uses one that is basically cut in half and drilled and tapped for the left-side charging handle. At the same time, he still has all of the modularity of a standard AR when it comes to triggers, parts, magazines, etc.
This Blackout can hold a 10 round, 20 round magazine. Not sure if it comes with a 30, but probably. You all can correct us on that.

The Cost
The Solo cost Duray about a few hundred dollars to make and he can use hand loads with bullets from 60-grains up to 265 with a very subtle sound signature when fitted with a screw-on can and minimal recoil. This gun looks like a fit for plinking, varmint hunting and loads of other fun with a suppressor.

We all love the AR platform because its so reliable and as long as you keep it maintain, it can last a life time.
The only drawback from this platform is the 5.56 cartridge. Some folks want a little more punch.
There have been some cartridges that have come down the pike as an alternative, but the only one that stands out is the .300 AAC Blackout.
The .300 AAC Blackout was designed to give the AR platform extra umph in terms of power and penetration on intermediate ranges with reduce recoil while holding the 30 round mag.
Its original intent was to provide outstanding terminal performance and accuracy going through suppressed with subsonic or standard ammunition. So here are the numbers.

Strengths & Weaknesses
Both calibers are used for the same general purpose.
Both cartridges are perfect for target shooting, hunting, home defense, and plinking.
Somethings to consider from each strengths & weaknesses.
-The 5.56 is half the cost of 300 BLK and is available in more high-end loading suitable for precision rifle fire.
-The 5.56 also shoots flatter, has less recoil, and the ammunition weighs about 40% less.
-The 5.56 is also safer for use inside a building for home-defense because the rounds are designed to break apart upon impact.
.300 Blk
-The .300 Blk has a wider range of projectile choices
– Due to the .30 caliber bore, burns its full potential in a 9-inch barrel, and is a much better choice for hunting.
-Has the ability to cycle both super and subsonic ammunition without modification.
– Its strengths shines with short barreled rifles and silencers and when barrier penetration might be needed.
– Whether for hog hunting from 0-200 yards or conducting CQB work, this baby is godsend.
Back to more numbers.

The table above you can see the compared ballistics of both the 300 BLK and the 5.56 NATO.
– Shows the barrels that the cartridges were designed approximately 20-inches for the 5.56, 9-inches for the .300 BLK, and the most popular civilian barrel length of 16-inches.
Exterior ballistics are the qualities associated with how a projectile flies through the air.
**The wind drift, bullet drop, and zero range all fall into the category of exterior ballistics.**

You can tell that the 5.56 is significantly flatter than the 300 BLK in flight.
This is due to a faster velocity.
-The .300 BLK uses bullets with a higher ballistic coefficient but isn’t moving fast enough to take advantage of its sleeker projectiles.
This is why the 5.56 shoots flatter, with less wind drift although having almost half as much energy.
Terminal Ballistics

Terminal ballistics of a round are the qualities it has when it hits the target.
The sectional density, the relationship of its mass and its weight, its ability to penetrate rather than fragment, and the wound channel it creates due to its bore size are all the study of terminal ballistics. (tissue damage)
It’s important to note that while energy numbers can give you an idea of power around is, it’s only a single data point.
The stouter bullets, with more mass of a larger caliber seems to be the more effective round.

To the untrained observer the 300 BLK seems to have the edge in terminal ballistics.
So which is better?
Target shooting, training, or plinking is just plain fun.
-It can get expensive when shooting so many rounds, so this round goes to the 5.56.
-The 300 BLK’s lethality and stopping powers isn’t needed when all you’re doing is punching targets that don’t fight back.
If you’re pressed with the $ issue, stick with the 5.56.
Home Defense
For home defense, you should be thinking heavy hitters, walk softly and carry a stick chambered in 300 BLK.
-Having a suppressor with subsonic ammo in a home defense situation is ideal for your hearing.
-The .300 BLK is still great when you either can’t or care not to have NFA firearms.
-If you find yourself in a state like California defending against zombies, with a tight magazine ban and zero NFA goodies, get the bigger bullet.
With modern bullet designs the gaps between the killing power of calibers is shrinking.
-If you’re into small game, go with the 5.56. The wide range of factory loading for predator hunting edges out the 300 BLK.
-If you plan on hunting medium or large game such as deer, hogs, or smaller bears, the 300 BLK is far superior.
-The extra mass gives more reliable penetration than the 5.56.
Here’s a video that demonstrates the comparison visually from Youtuber Langley Firearms Academy.

In the End
The .300 BLK will never replace the 5.56 for the most ubiquitous AR-15 cartridge but it does have some key areas where it really shines.
Let us know below when you can think of a time where you wished your AR-15 had some “umph” to it?

solves the need for multiple magazines


Review and photographs by Oleg Volk

unimag_loaded_leftside_DSC3966With the proliferation of AR15s and STANAG-compatible rifles, many of us end up having to keep numerous incompatible magazines on hand. For example, 6.8mm SPC and 338 Spectre require one type, 223 Remington, 300 Blackout and 458 SOCOM another, 7.62×39 a third. Keeping them straight for a range trip is half the problem. Changing over chest rig pouches from mostly straight 223 to curved 7.62×39 is more annoying. And the cost of getting numerous magazines for every caliber isn’t trivial, either. The Unimag by Ross and Zheng Engineering solves this problem by using a stainless-steel body shaped much like a regular GI magazine and a clever articulated follower that automatically adjusts to the shape of the cartridge column. It worked well for me in a variety of AR15s, ARAK21, TAR21, RDB, MAD556 (a roller-lock rifle with very fast cycle). The magazine body is treated with slick anti-corrosive finish on the inside and with textured finish on the outside. This design should be of a special interest to 458 SOCOM users, as it holds a dozen large-bore rounds instead of the usual ten that fit in a conventional GI magazine. unimag_loaded_DSC3972
