Lightweight Chrome BCG Review
Written by: Buddy Murphy
This is a review of the Semi-Auto/Full Auto M16 Complete Bolt Carrier Group (BCG), manufactured by Young Manufacturing Inc. This bolt carrier group is manufactured using MIL-SPEC quality steel and milled on their in-house CNC machines, ensuring precision and reliability in every component. The particular carrier in this review is their SLC (Super Lightweight Carrier), which they no longer have on their site, but can still be found for sale on 3rd party sites. All attributes from this carrier extend to their M-16 BCGs - except weight.
Each bolt carrier undergoes a meticulous process of getting heat-treated, hard-chromed, and the bolt throat is then chrome-lined for enhanced durability and performance. They remove all sharp edges and rough finishes. Ensuring smooth operation and preventing any unnecessary wear and tear on your firearm.
What does hard-chrome do for you? Well, it adds durability to the BGC and it makes the surface very hard so carbon has more of a problem sticking to it. Here are some before and after pictures. With half of a dry paper towel and about 10 minutes, this BGC went from this…
…to this.
That carbon has been building up since Forgotten Weapon’s “Moons Out Goons Out” in March of 2024. It has done several other competitions and practices since – all suppressed in a direct impingement rifle. I have run Nitrided BCGs and they will get sticky (and NiB to a lesser extent) after getting a sufficient amount of carbon, this BCG did not get sticky. I have become a Piston AR snob because of direct impingement BCGs becoming inoperable without constant care, when shooting suppressed. But with this BCG, I am starting to question my own snobbery.
Now, let me draw your attention to the innovative HMB Bolt by HM Defense, that is included in this carrier group. The HMB Bolt represents a significant advancement in bolt design by eliminating the traditional pass-through cam pin hole. Replacing it with a cam pin socket and radiused cam pin. This patented design addresses the inherent weak point in Mil-Spec bolts. It increases the amount of metal—and thus strength—at the cam pin location. The result? No more broken bolts, at least at the cam pin.
Moreover, the HMB Bolt reduces contact between the cam pin and firing pin, allowing for smoother operation of the firing pin, bolt lugs, and aft gas rings. The cam pin socket also retains lubrication, ensuring extended operational performance.
You may have noticed in the photos that the gas key is not staked, that is intentional. Here is a link as to why they don’t stake their gas keys from the Young Manufacturing President: Read it here. The long and short of it is if you do it well enough, they don’t need staking. The gas key is supported by a recoil lug, a feature designed to enhance overall reliability and function.
