I'm looking at the Young Manufacturing AR-15 Bolt Carrier Phosphate Complete. 1. What can you tell me? 2. Would it be better to get a chromed BCG? 3. What other coatings are available and what are the benefits? 4. Is Phosphate the same as parkerized? 5. How does this unit compare to the Bravo Company BCM? 6. How does this unit compare to CMT or LMT BCG's? |

The BCM as offered by Bravo is very good quality. They are greenish parkerized steel with a hard chrome interior as they are suppose to be. The price of the BCM is right as well. This is all that I can offer you. What are you looking for in one? If you get a complete chrome one v/s mil spec chrome lined, then it will be nice and shinny thru your ejection port, is that what you want? Phosphate and parkerizing are the same, depends on who is selling the product. |

A M16 bolt carrier alone along with normal AR15 parts cannot fire full auto. The parts that make it a full auto are in the trigger group, inside the lower, so an M16 carrier in the upper doesn't even begin to fall into that area. Here is a partial " cut & paste " reply from one of the users form "the highroad.org" "Any weapon which shoots automatically, more than one shot, without manual reloading, by a single function of the trigger, is a machinegun as defined in 26 U.S.C. 5845(b), the National Firearms Act (NFA). In addition, the definition of a machinegun also includes any combination of parts from which a machinegun may be assembled, if such parts are in possession or under the control of a person. An AR-15 type assault rifle which fires more than one shot by a single function of the trigger is a machinegun under the NFA. Any machinegun is subject to the NFA and the possession of an unregistered machinegun could subject the possessor to criminal prosecution. Additionally, these rifles could pose a safety hazard in that they may fire automatically without the user being aware that the weapon will fire more than one shot with a single pull of the trigger. In order to avoid violations of the NFA, M16 hammers, triggers, disconnectors, selectors and bolt carriers must not be used in assembly of AR-15 type semiautomatic rifles, unless the M16 parts have been modified to AR-15 Model SP1 configuration. Any AR-15 type rifles which have been assembled with M16 internal components should have those parts removed and replaced with AR-15 Model SP1 type parts which are available commercially. The M16 components also may be modified to AR-15 Model SP1 configuration. The first and second paragraphs define what a machinegun is. More than one shot per trigger pull = machinegun. They say nothing about any specific part making an AR15 a MG. The last paragraph says that IF you have none of those parts, THEN you do not have a machinegun." Here is another one: "It's NOT illegal. Those are ATF guidelines for company's manufacturing ARs. If you don't have enough parts to make the gun go bang more than once with one pull of the trigger, or in a condition that it can be readily adapted to do so, you are not in violation of the law. Auto-sears are considered "machine guns" in and of themselves, so obviously that part would be a no-no. If you possess an AR15 and the M16 fire control parts, you're breaking the law. Many DCM shooters use the M16 carrier, including me. There's a simple reason for it. It is heavier.... it keeps the bolt locked for a tiny fraction of a second longer which reduces primer set-back and blown primers. It has nothng to do with making the gun full auto.... all the 16 carrier does in that capacity is trip the auto-sear.... which releases the disconnector....without the sear, 16 disconnector, 16 hammer, selector and trigger.... you're not gonna get more that one round off with one pull of the trgger. The only 16 parts I own are carriers, Many many thousands of early ARs were manufactured with M16 bolt carriers."
