Hope your PSA pistol upper runs for you. I was running a heavy buffer and full auto bcg and still had to go with an adjustable gas block to get it to cycle right. But once it was tuned in

Non full auto cut carriers have less material, and some say can break easier. Most non full auto cut carriers aren't properly staked, and may not have an MPI/HPT bolt.
Just buy a quality full auto or m16 bcg and be done with it op. |

Ok, in all seriousness I have an LMT with an M16 and SR-15 with a semi auto carrier. No issues from either. If I bought a new one, I'd just get a full auto BCM and call it a day. If I had cycling issues, I'd remedy those by tinkering with the buffer weight and spring before I got a lighter BCG. |

I can't say for sure, but I have been told bolt weight can be a factor in recoil in a rifle. I can't remember if it lowers recoil or not though. I'd guess it "absorbs" recoil being heavier?
If that's the case, it would be better in a pistol I'd assume. along with the proper buffer. But people who know what they're talking about will be along shortly. |

Quote HistoryQuoted:
Why are semi auto carriers even still made? Why were they created in the first place? I'm assuming some feel good lawyer crap. Because the ATF issued a bulletin to all FFL's back in the mid 1980's that said having ANY full auto components in an AR-15 was considered a machinegun. Around 2005 Colt wrote the ATF a letter asking if installing a Full Auto BCG constituted making a machinegun. ATF s did not specifically endorse the use of a full auto BCG, but stated if the addition of the full auto carrier did not allow the rifle to fire more than one shot per single function of the trigger it was not a machinegun under the NFA. Therefore Colt began shipping their rifles with the Full Auto profile BCG's and soon everyone else began to follow suit. |

If any of your other ARs have a semi BCG get the M16 cut one, if it does not cycle properly just swap with an AR cut one.

The reason the cut AR15 carrier is in existence is to make the bolt carrier, hammer, and firing pin bind up if you attempted remove the connector.
The notch exposes the rear of the firing pin to the notched hammer, and if the hammer was still tripped as the bolt slid back into battery, the notch cut into the ban area bolt carrier would ride up and catch the edge of the exposed firing pin thus jamming your rifle. |

Quoted:
My complete rifles obviously came with BCG's. I've done some lower builds, but bought complete uppers that also came with BCG's. Now I'm doing an AR-pistol build, and the pistol gas length upper I got on a PSA Black Friday deal does not come with a BCG. I plan on using the pistol with a SIG SBX brace, and a buffer / spring / tube that come together as a package. So, back to the BCG....are there pros and cons to getting a 'full auto' cut vs. a 'semi' cut in a semi pistol? I assume the full auto cut has more weight to it... Educate me please. The Full Auto cut BCG's seem to be more reliable to me. YMMV. |

Damn! I've never seen more BS in all my life. There is zero advantages to using a auto carrier over a SA carrier in an
AR15. Anyone who believes otherwise is just plain ignorant. Luckily ignorance can be cured. The only difference between a semi and auto carrier is a very small amount is cut back more on the semi. The amount cut back is so it cannot trip an auto sear. The difference in weight is .3 grams, that's 1/100 of an ounce. Anyone who believes that 1/100 of an ounce will make any difference in the operation of the action in an AR15 is just plain stupid, for that, sadly, there is no cure. ETA: Now the old Colt half circle carriers, that's a different thing. Those were just plain stupid from conception. |

Unless your looking for reduced weight/recoil but a plain SA carrier isn't going to give you either. There are plenty of specialty carriers designed for low mass. Quote HistoryQuoted:

Driving the hammer with the firing pin, instead of the bolt carrier, is my biggest gripe with them. m16 is m16. Plenty of ways to skin the semi cat, and god only knows what fuckery was decided upon. |

Out of curiosity, I just went through the safe and checked the BCG's in all my rifles. Having not paid specific attention before, I was surprised to see that they were all 'full auto' cut BCG's. Not having had any cycling problems with any of them...from different manufacturers...I guess I'll stick with what has been working.
