What You're Getting
This is a 100% USA made M16 full auto cut bolt carrier group — the same Colt-spec carrier used in our Super Safety combos, now available as a standalone unit. Everything from the carrier body to the bolt is domestically manufactured to mil-spec tolerances. This is a complete, drop-in BCG ready for any mil-spec AR-15 upper.
The M16 full auto cut carrier is heavier than a standard AR-15 carrier. That added mass produces a slower, smoother recoil impulse — improving reliability across a wider range of ammunition, suppressed setups, and adverse conditions. It is fully legal in all 50 states and functions identically to a standard BCG in any semi-auto lower.
M16 Cut vs Standard AR-15 BCG
M16 Full Auto Cut
Full relief cut on the underside of the carrier. More mass. Smoother, slower recoil impulse. Better suppressor compatibility. Compatible with all mil-spec AR-15 uppers. Legal all 50 states in semi-auto builds.
Standard AR-15 BCG
Lighter carrier, no relief cut. Functions identically in semi-auto. Less mass means a sharper, faster recoil cycle — less forgiving in adverse conditions or suppressed setups.
Why M16 Full Auto Cut
- More reliable cycling — heavier carrier provides greater momentum through full travel, clearing dirty or underpowered ammunition that stops lighter carriers
- Smoother recoil impulse — added mass slows the carrier slightly, distributing recoil over a longer window for a flatter, more controllable feel
- Suppressor optimized — M16 carriers handle increased backpressure from suppressed fire more reliably than standard carriers
- Super Safety compatible — the M16 carrier's consistent cycling impulse pairs ideally with the Hoffman Tactical Super Safety's active reset cam
- Drop-in installation — fits all mil-spec AR-15 uppers with no modification required
What's Included
- Carrier — M16 full auto cut, Colt-spec geometry, 100% USA made
- Bolt — mil-spec, USA made, ready to run
- Cam pin — mil-spec
- Firing pin — mil-spec
- Firing pin retaining pin — mil-spec
Fully assembled. Drop it in and go.

Pairs With
This BCG is the same unit included in our Super Safety combo bundles. If you already run a Hoffman Tactical Super Safety or are building a new Super Safety setup, this is the recommended carrier — the M16 cut's consistent cycling impulse gives the Super Safety's active reset cam the most reliable interface possible.

Frequently Asked Questions
What is an M16 full auto cut BCG?
An M16 full auto cut BCG has an additional material relief cut on the underside of the carrier compared to a standard AR-15 carrier. In a semi-auto lower it functions identically to a standard BCG. The M16 carrier is heavier, which provides more reliable cycling, smoother recoil impulse, and better performance in suppressed setups.
Is an M16 BCG legal in a semi-auto AR-15?
Yes. An M16 full auto cut BCG is legal to own and use in a semi-auto AR-15 in all 50 states. The BCG itself is not a regulated component. Installing it in a semi-auto lower does not convert the firearm to fire automatically — full auto fire requires additional registered components. The M16 BCG simply functions as a heavier, more robust carrier in your semi-auto build.
What is the difference between an M16 BCG and a standard AR-15 BCG?
The primary difference is the full auto relief cut on the underside of the M16 carrier and slightly more mass. The added weight produces a smoother, slower recoil impulse which improves reliability, especially with suppressors or adverse conditions. In a semi-auto lower, the M16 BCG fires and resets identically to a standard BCG.
What does Colt-spec mean for a BCG?
Colt-spec refers to the dimensional and material specifications set by Colt, which established the original mil-spec standard for AR-15 and M16 components. A Colt-spec BCG meets or exceeds the original military tolerances for carrier geometry, bolt material, and gas key staking.
Does this BCG work with the Hoffman Tactical Super Safety?
Yes. This M16 full auto cut BCG is fully compatible with the Hoffman Tactical Super Safety. The Super Safety's active reset cam interfaces with the carrier as it cycles — the M16 cut does not affect this interface. The added carrier mass can actually improve Super Safety reliability by providing a more consistent cycling impulse.
Is this BCG 100% USA made?
Yes. This bolt carrier group is 100% USA manufactured — carrier, bolt, cam pin, firing pin, and retaining pin are all domestically produced to mil-spec tolerances.
Does this BCG come with a bolt?
Yes. This is a complete bolt carrier group — it includes the carrier, bolt, cam pin, firing pin, and firing pin retaining pin, fully assembled and ready to drop in.

An epic adventure with a rich cast of characters
Format: Paperback
Scout paints the Mojave as bursting with life, a poetic world full of chaparral and chinquapin, of creosote scrub and conifers. These wild vivid landscapes are a backdrop to the real heart of the story, which, like all great stories, is always about People.
The Human Drama, sometimes of People vs the Environment, but more often of People vs Themselves. Overcoming our own fears or injuries or burdens that life inevitably deals to us all. This book captures the pursuit of people stretching themselves, challenging themselves to change and grow.
He does an excellent job of capturing the "esprit de corps" of the trail, of near strangers and fast friends looking out for one another, and the crescendoing intensity as they race against Father Winter. We meet a wide ensemble of characters, which is one of the most magical aspects of any long hike. It is the great equalizer, where people from all walks of life come together and share fellowship.
There are numerous role models within this book. It is impossible to not be inspired by Jan, the quintessential Fixer, or the protagonists who demonstrate exemplary examples of forgiveness and reconciliation, and other humble benefactors and do-gooders who understand that their gifts are more than simply money. They are giving opportunity. The fixers, the reconciliers, the benefactors....we should all aspire to be these types of people.
I hope this is but the first of his trail books. I'm certain there are many of us who would enjoy reading about his adventures from New Mexico to Montana as well. How fortunate was he to meet such wonderful people, and how fortunate are we to share their experiences from the comfort of our homes.

OK book about hiking the Pacific Crest Trail.
Format: Paperback
I love books about people hiking the national trails. I thought this book was about the author's thru hike on the trail with his wife. Actually, this book had little to do with the Pacific Crest Trail and was mostly about the other hikers, their relationships, etc. It read like a fiction book, as the author often gave examples of conversations the other hikers had with other people, even when he wasn't around to hear them. He also gave examples of what they were thinking and even what the other hikers friends were thinking. There was no evidence of interviews, etc.
It is a very well written book, so I gave it four stars. If you like books about the relationships of thru hikers, especially their romances, I would recommend this book. But it reads more like a fiction book, in my opinion.

Walking from Mexico to Canada with a great cast of characters
Format: Paperback
I thoroughly enjoyed reading Journeys North. The story is about the Pacific Crest Trail and the people who hike it (thru-hikers) attempting to walk from Mexico to Canada. The author brings the trail to life across the story, but what really stands out is the story of the characters. You find yourself rooting for them as they encounter all kinds of challenges, and you get to know them through their backstory and past experiences that are shared. People attempt a thru-hike for many different reasons, and the story is enriched by their personal stories and histories that they carry with them each step of the way. Even their “trail names” had stories that often highlighted something about the characters themselves. One of the unique things about the book is the Pacific Crest Trail itself, as the author’s descriptions allow you to imagine what it looked like and felt like (including the aches, pains, and injuries along the way). The trail is ever present across this story of the people who walked it, bring them together, and then pulling them away from one other, sometimes for weeks or even months. The trail and mother nature create for an everchanging backdrop as the characters navigate their way north. I am not a thru-hiker and I doubt I would ever attempt to walk from Mexico to Canada, but I enjoyed tagging along on the adventure of Scout, Frodo, Blazer, Dalton, Tony, Nadine and many others whose lives intersected over the course of many miles. I found myself having a hard time putting the book down, particularly as the hikers neared the Canadian border. If you are looking for an armchair adventure along the PCT, or wondered what it would be like to tackle a thru-hike of a long trail, or are curious about the people who undertake such a challenge, you will enjoy Journeys North! I would imagine that if you are a PCT hiker you would find the book even more meaningful.

Incredible Life experience while hiking the PCT
Format: Paperback
As I began experiencing great stories about the "Camino" pilgrimage in Spain, books about "thru hikes" in the US seemed to find me too i.e. The Pacific Crest Trail, and did grab my attention for various reasons...
"Journeys North"-- To me, this story makes it more than apparent, that if you want to learn about yourself and open your "vault doors" so to speak, and free yourself of personal challenges-hiking the PCT could help. This book on it's own, is a wonderful treatise about the PCT, and taught me much about being open and honest with others to include oneself, and about being grateful."
This story "rings" of Freedom, is intense, and at times, raw. From the comfort of my living room... Frodo, Scout, Blazer, and company drug this old backpacker (me) a.k.a. "LightningLayne" along on a fantastic journey north clear from Mexico's northern border to Canada's southern one. Along the way, I noticed how the "goodness" in people replaces just about every negative the world throws in your face. Finally, I laughed, I cried, and even felt sorry at times for all the "participants." In the end, I was "grateful" for the individual and collective stories shared. This story is one that has burrowed in deep and is one I will never forget.
