5 Best .300 Blackout Bolt Carrier Groups (BCG)

It is no easy job to find the right BCG for a .300 Blackout.

The explanation is that the business is saturated with a lot of them.

Many are inexpensive and low-quality, making it hard to find a decent one that exactly suits a rifle.

We’ve taken the liberty of hunting down five of the strongest BCGs for a .300 Blackout to minimize the amount of headaches and lost time, nonetheless.

As of this writing, these are what we consider to be the strongest on the market.

We’re going to explain what a BCG is and the purpose of it before we unveil the list.

On top of that, we’ll give you a few fast tips on how to pick a BCG of high quality over a model of low quality.

What is a BCG, and how does it function?

BCG stands for Bolt Carrier Party, first off. It is supposed to be the .300 Blackout rifle’s core.

It is pretty much worthless without it. This is the engine, so to say, of your vehicle.

And, of course, if the vehicle does not have a working motor, it can not work.

So what would the BCG do with your rifle, exactly? It is built to guarantee that you have consistent shooting patterns and are less prone to glitch and jam.

The same can even be said about your rifle’s reloading system.

That’s what you ought to expect from a BCG of decent standard. It’s pointless if one always jams or causes you grief throughout the reloading process.

The bolt in this accessory is built to lead the next round through the magazine through the chamber that emerges.

It would also guarantee that the round is properly positioned and completely balanced such that it will not jam before ejecting.

Aspects to Remember Before Buying a BCG

Blackout Bolt Carrier Groups (BCG)

The crucial thing is to realize what considerations are going to go into your decision making before you can suggest buying a BCG.

Not only is seeking out a product on a whim unwise, but it may also be a dangerous decision.

Not only can a continually malfunctioning accessory create issues for your weapon, but it may also pose a safety danger.

When selecting a high quality BCG, this should be worth bearing in mind.

With that in mind, before making a purchase, here are several things to consider:

Price

If you are a .300 Blackout rifle owner on a budget, in your purchase choice, you would obviously regard price as one of your key considerations.

That is totally comprehensible.

One thing you ought to hold in mind is that in your decision, price should not be the only consideration.

The aim here is to find a high quality BCG that is sold at a price that suits most budgets.

The primary explanation is to guarantee that you avoid buying low-quality and cheaper goods and do not break the bank by purchasing it.

Material

As stated, prior to everything else, consistency should always be a top priority.

That is why it is important to pay attention to which materials are used for the development of these BCGs.

They can typically be produced from a high-quality steel or aluminum nine times out of ten.

Blackout Bolt Carrier Groups (BCG)

The chrome lining used on the inside of the BCG itself is one aspect to pay careful attention to.

It is meant to protect the interior from rusting or corroding.

If you see a BCG that does not, in fact, have this chrome lining, avoid it at all costs.

Without the correct lining, the durability will not be as long-lasting.

Installation Difficulty

The BCG is, of course, what makes a rifle work. So, naturally, it needs installation.

How quick it is to install is the key thing to search for in a BCG.

The keywords you want to check for are “drop in” when seeking something that is quick to install.

Drop-in suggests that without the use of equipment or a gunsmith’s technical facilities, they are simple to mount.

Full-Auto vs. Bolt Carrier Groups for Semi-Auto

So, what’s the difference between bolt carrier groups that are fully automatic and semi-automatic?

And is it lawful to possess them? The quick response to the issue of legality is yes.

Bolt Carrier Groups

However, prior to buying, it is necessary to double check the local and state rules, just to be sure.

Other than that, there is a rear lug in a completely automatic BCG that will force the sear release downward, enabling the gun to shoot in full auto mode (or burst shoot mode).

Semi-automatic BCGs are cut in particular, so they would not take up a ton of mass.

If you want the highest of durability, the lower volume of mass is indeed a bonus.

Compared to their full-car counterparts, Semi-Auto BCGs are more affordable.

Final Verdict

It doesn’t have to be a struggle to find the right BCG for a .300 blackout.

However, if you want your .300 Blackout rifle to work properly, it is a must-have.

It may take some time to look, but it’s important to find the right one that suits your rifle correctly and can last you for years or even decades.

When you come across a BCG that you like before purchasing, make sure to do more in-depth analysis.

We hate the remorse of the customer and don’t want you to go through that.

So be careful to listen to what people are talking about it and, when the time comes to pick your own BCG, use your best judgement.

BROWE 4×32 Combat Optic with .300-AAC “Blackout” reticle

BROWE 4x32 Combat Optic with .300-AAC

US-based BROWE Optics is launching a variant of its Combat riflescope with reticles for the increasingly popular .300-AAC “Blackout” caliber.

BROWE Optics, Inc. is a company based in Madison Heights (Michigan, USA)It sells DOCTER Optics and American-Defense-Mfg. mounts as well as its own brand 4×32 BCO (“Browe Combat Optic”).

This includes modern tactical riflescopes for numerous calibers and tactical applications as a robust, reliable and cost-effective alternative to well-known brands such as Aimpoint or Trijicon.

At the end of August 2012 BROWE announced the launch of a special version of the 4×32 BCO specifically for use with the .300-AAC “Blackout” caliber.

This is a cartridge that is gaining increasing popularity among American shooters.

BROWE 4×32 BCO optics are based on an internally adjustable optical system with roof prisms and an etched glass reticle, thus maintaining a short overall length.

This system has proven to be successful with products currently in use.

All BROWE lenses are precision ground from optical glass of the highest quality and are given an anti-reflection coating to make optimum use of residual light even in poor light conditions.

The reticle etched into the glass contains an LED with microprocessor technology and a cadmium sulfide photocell for measuring the target light conditions and automatically adjusting the reticle to the light conditions in the target.

BROWE 4x32 Combat Optic with .300-AAC

The 4×32 BCO .300-AAC “Blackout” reticle is based on the popular horseshoe and dot system and features a BDC (Bullet Drop Compensated) reticle for subsonic and supersonic ammunition.

The 7-MOA horseshoe has an inner diameter of 5 MOA and an illuminated ring of 2 MOA for fast target acquisition.

The central point of 1 MOA enables the shooter to fire precisely and is designed to be shot with Supersonic ammunition at 100 m or Subsonic ammunition at 25 m.

For long-range precision, the 4×32 BCO .300-AAC “Blackout” reticle contains a BDC reticle that covers up to 900 m for Supersonic and 400 m for Subsonic ammunition.

The horizontal measuring lines stand for 48.3 cm at the specified distances.

The reticle also features a horizontal milli-scale.

The 4×32 BCO AAC .300 blackout reticle is available in four color selections (yellow, blue, green or red).

Standard on all 4×32 BCOs, illumination is automatically controlled by BCO target light sensor technology.

The target light transmission is measured and the reticle is automatically adjusted to the correct illumination level.

The 4×32 BCO also provides manual override if a uniform light level is required.

SIG SAUER Elite Performance .300 AAC Blackout

News- Update // SIG SAUER expands its in-house ammunition series Elite Performance with .300 AAC “Blackout” caliber rifle cartridges.

The ammunition is intended for sport shooting and tactical applications in the AR-15 range. By the way, this is the first rifle ammunition from SIG SAUER.

SIG SAUER Inc, the North American subsidiary of the well-known German company, expanded its defensive ammunition series Elite Performance by launching new loads and calibers at the SHOT Show 2020.

The largest and most important addition to the series is the .300 AAC “Blackout” charge, the company’s first rifle ammunition on the market.

Designed for the AR-15 platform, this subsonic cartridge features a SIG SAUER-style 220 grain open-tip bullet (OTM), which is equipped with SIG Sauer’s proprietary lead alloy core for improved precision.

At the end of 2020, the new Elite Performance ammunition series from SIG SAUER will be further expanded with a supersonic variant of this caliber, the manufacturer told us at the SHOT Show.

This recoilless cartridge is ideally suited for use with a silencer, which significantly reduces the sonic image and muzzle flash.

This makes this ammunition one of the favorites of sports shooters who want to protect their hearing and tactical shooters who want to avoid noise and muzzle flashes. Moreover, many hunters with modern sport rifles prefer this cartridge even for limited hunting applications.

Especially when using a silencer, it is fun to shoot “blackout” with the 220 grain subsonic .300 AAC cartridge.

It can be loaded into a standard STANAG 4179 magazine without loss of capacity.

Modern sport rifles with chambers for 5.56 x 45 mm / .223 Remington can be converted to .300 AAC “Blackout” simply by replacing the barrel or the entire top of the case.

The Elite Performance series from SIG SAUER will be further expanded in the coming months.

The range of rifle ammunition for hunting and the tactical market will be added and the pistol ammunition range will be expanded.
