| Just finished my first build and I am anxious to do a live fire test. I have a PSA Premium full-auto BCG that I am using for this rifle, and it is in the cardboard shipping tube dry as a bone. I know that I need to thoroughly lubricate the BCG, but I would like to hear from y'all on what you do to prep a new BCG for service. |

Lube 'er up good, especially the bolt lugs and go shoot.
Good reference at the beginning of this thread. |
| Thanks for your post! That was my initial thought. I am not new to mechanics, just new to building these rifles (and to this forum). And, I have heard stories of people soaking new BCG's in motor oil and all kinds of other stuff. Just didn't want to do anything that was going to lock up my rifle on the first shot, then hear "well you shoulda' ..." |

interesting seeing people's different "rituals" for this. Me I just hit them with some brake cleaner, like I do all new parts, to strip off all the oils and dirt. Then lube them up (will take more since it strips the oil out of the pores) and let it soak in. Add a bit more lube if needed, then toss it in the gun and off it goes. Then again I use brake cleaner for a LOT of things. |

Then again I use brake cleaner for a LOT of things. This. New parts are shipped with some amount of "protective coating" (even the PSA premium BCG, just not on the phosphated surfaces) which is NOT a good lube. Cleaning that stuff off before lubrication helps by getting gunk out of the surface structures (pores, mill marks, etc.) of the metal. Then apply lube liberally and let it sit a while. That phosphate coating will hold plenty of lube. But don't forget the insides of the carrier, and especially don't forget to lube the bolt parts like the ejector and extractor. This isn't a "ritual," as much as a "proven practice," and it takes just a couple of minutes to do. Strip the BCG to the major parts, clean the gunk off of them, oil 'em up and reassemble. When it's all together and you've made sure the bolt moves smoothly in and out of the carrier, wipe off any heavy excess of lube. A new BCG will run better if you keep it kinda wet for the first several magazines. |
| Thanks to everyone who weighed in on this simple question. Apart from the fact that I wanted to get some direction from some seasoned vets, I thought it would be interesting and educational to hear the different approaches that people take when putting a new BCG into service. If anyone else who reads this thread has anything different that you do in this situation, please share. Otherwise, thanks again for your input! |

This. Except I also do a quick clean as well before lubing the first time. Tomac Quoted:

Lube and shoot This. Except I also do a quick clean as well before lubing the first time. Tomac This, I usually strip the BCG completely and clean/lube everything real good. |
