#1 Aero Precision .308 BCG (Black Nitride)
The first model we are going to review is a good but rather expensive solution for big-bore builds. This .308/7.72 BCG is made of case hardened 8620 steel, and it’s also high pressure tested and magnetic particle inspected. Thanks to high-quality coating and solid elements, you can enjoy a long-lasting and smooth experience. The carrier has forward assist serrations for better performance.
#2 ODIN Works Nitride BCG Black
For a lower price, you can find this interesting model. A bolt carrier group made of Case Hardened 8620 Steel with nitride finish that is compatible with mil-spec uppers. An attached with Grade 8 hardware 4130 steel gas key and high pressure tested bolt together with O-ring compatible extractor and mil-spec firing pin allows you to feel what the real shooting is. So don’t miss this device if you see it on the market.
#3 FosTech Outdoors AR-15 Complete BCG
If you need a full-auto BCG compatible with Echo AR-II and the Echo Sport, this model is a good purchase. Good balance, affordable price, durable materials — this is what you want to see in a bolt carrier group for your AR-15 rifle. As always, nickel-boron coating reduces the need for lubricants and ensure corrosion resistance, so you don’t have to worry about the lifetime.
#4 Spikes Tactical M16 BCG
One more full-auto M16 BCG made of mil-spec 8620 tool steel that offers good characteristics for a quite standard but yet not cheap price. All elements are high pressure tested and MPI marked. The bolt is shot-peened, and the carrier key is firmly attached with Grade 8 hardware. The O-ring on the extractor facilitates installation and use. It’s a reliable model that is totally worth buying if you need such parameters.
#5 RISE Armament AR-15 BCG
A nice, durable, and well-tested bolt carrier group for 5.56x45mm NATO, .223 Remington calibers can make you satisfied not only with decent characteristics but also with a nice price. A magnetic particle inspected bolt made of 9310 steel, a heat-treated 8620 tool steel carrier, reduced friction, and smooth operation will make your shooting experience simple and enjoyable. The gas key is staked properly, and the extractor is shot-peened.
#6 FosTech Outdoors AR-15 Complete Lite BCG
What have we got here? This is a low-mass bolt carrier group that is designed for 5.56/.223. caliber and it has some peculiarities. First of all, it’s really lightweight, and it’s only 8.6oz. Due to such sizes, this model is not mil-spec compatible. The finish is one of the strongest advantages of the BCG. If you want to make a lightweight but solid and reliable build with no glitches and snags, it’s a perfect solution. However, it will cost you some money, so be ready for it.
#7 JP Enterprises Complete JPBC BCG
Talking about lightweight BCGs, we should mention a 9mm bolt carrier group designed by JP Enterprises. It’s one of the most reliable 9mm systems, and it features reduced stroke length, reduced bolt bounce, and a tighter firing pin channel. Thanks to these elements, the bolt carrier group is very durable but lightweight. The finish here is also good, it increases reliability and allows you to forget about the constant use of lubricants.
#8 Aero Precision AR15 5.56 BCG
In the 8th place, we have an M-16-cut bolt carrier group machined from 8620 steel and designed for 5.56x45mm NATO caliber. Despite the low price, this model has a nice range of features that any professional or amateur shooter will like. First of all, materials are solid. Besides, the BCG is shot-peened, high pressure tested, and magnetic particle tested. The gas key is firmly attached and properly staked. The extractor has an O-ring insert for easier use. In addition to this, forward assist serrations make operation smoother.

Another model by ODIN that makes customers happy for a long time. There is nothing special about this bolt carrier group — it’s all about the perfect balance between the price and characteristics. Here you will find a mil-spec compatible BCG made of case-hardened 8620 steel and coated with a black nitride finish. All details are HPT tested and MPI marked, the operation is smooth and simple. Build an accurate, reliable, and cheap rifle with custom elements like this.
#10 FailZero M16/M4 BCG
Regarding this model, it’s a cheap but great solution for 5.56/.223 calibers for M16/M4/AR15 rifles. It’s super easy to install on the majority of mil-spec uppers, and it ensures nice durability thanks to the EXO nickel-boron coating that reduces friction and corrosion. It can be a great add-on for your fire-arm, so don’t think twice if you can buy it. This will be a good buy.
#11 TRYBE Defense Milspec Complete 9mm Hybrid BCG
If you have a 9mm AR-15 carabine, this BCG is what you need. It’s suitable for Colt- and Glock-style lowers and it ensures good durability and smooth, fast operation. This model is made of 8620 steel and has a nitride finish, which means no extra friction while operating and long service life. The BCG has mil-spec dimensions.
#12 Ballistic Advantage .308 BCG
Thanks to an 8620 alloy steel carrier and a bolt made of 9310 alloy steel, this 7.62/.308 BCG BCG designed by Ballistic Advantage ensures nice performance and durability. The only downside of this model is, probably, the price because it’s not low. All the characteristics are good, and the features are useful. Except for high-quality elements, this bolt carrier group offers a properly staked gas key, a shot-peened bolt, high pressure tested and MPI marked details, Viton O-ring, and forward serrations.

#14 FailZero AR15 BCG
Previously, we’ve been reviewing the same bolt carrier group but without a hammer. This model has a hammer and offers the same range of features. Basically, it’s a good, balanced, and very durable bolt carrier group that comes with a hammer. Nickel finish makes this BCG even better, ensuring smooth operation and resistance. Improve any semi-auto AR-15 rifle with a good-looking and easy-to-use BCG.
#15 Midwest Industries 5.56/AR15 C158 BCG

Tactical accessories are another passion of mine that I could write about endlessly - my house and garage are full of tactical gadgets, luckily my family shares my interests.
I'm infatuated with traveling that's why work at one place with a daily routine and standard schedule is not for me. I prefer copywriting and English tutoring as a freelancer. I live in a male family among constant talks about cars, guns, hunting, fishing, and, of course, dinosaurs 😊.
My husband is an obsessed hunter, and my two sons are fans of «Demolition Ranch» of YouTube blogger Matt Carriker. They are my best consultants about weapon and all-around ammunition topics. All together we share a love for adventures. Every camping or mounting hiking trip is a "small survival", giving irreplaceable experiences. Nothing can be better than the satisfaction of observing wild nature.
