Does anyone have data on carrier weights?
Unshrouded Colt C carrier Unshrouded Ar15 carrier Shrouded Ar15 carrier Shrouded M16 carrier Want to see if carrier lightening is worth it for a lightweight build... dont want to do a skeletonized carrier, aluminum carrier or titanium carrier as I dont want to have to do an adjustable gas tube and adjustable gas blocks would end up costing weight vs saving it and not be as reliable and hassle free. If I cant save at least a full ounce vs an M16 carrier its not worth it for me. |

These carrier weights are with gas keys. Bolt, cam pin, firing pin, and cotter pin had been removed. Unshrouded Colt C carrier - 8.6 oz Shrouded LMT AR15 carrier - 9.2 oz Shrouded Colt M16 carrier - 9.5 oz Note: I used a digital postal scale and weigh it at least 10 times each carrier to eliminate any errors. |

Awesome, thanks a ton! Has your C carrier been reliable for you? I have never run one before. Yes, my Colt C carrier runs fine but I've only been running it on my Colt R6530 Sporter Lightweight carbine with a Colt A1 length fixed stock (A2 style), rifle metal buffer and my upper was an A2, 16" lightweight gov't profile carbine barrel. I mostly use Winchester white box 55 gr and Mil surplus 62 gr ammo no FTF at all. |
| The heavier the carrier the longer it takes for the bolt to open. We're talking miliseconds, however, if you plan to run heavy bullets with full charge loads go with a heavy weight carrier. The only people running light weight carriers are three gun competitors shooting 40 grain bullets as fast as they can. As fast as they can means their trigger finger AND velocity. Heavy carriers allow chamber pressure to subside when using 68 to 77 grain bullets. Nobody will know the difference under normal shooting conditions and you're primers will thank you for it. |

I understand this already, but thanks... and the gun will be running 55 grain ammo. My personal rifle has an M16 carrier and H2 weight buffer that rund 75 grain TAP. My goal is strictly the least weight with full reliability using 55 grain ammo for this build. |
