| I recently purchased a Young MFG lightweight chrome BCG. It looks like it's just skeletonized for lighter weight and shorter cycle times. This is my first upper build, but coming from anyone that's used them before, is there anything I need to look out for? Should a standard buffer work alright with it? |
Use an adjustable gas block to tune the system and you'll be happy.

What problem were you trying to solve? BSW |
| No problems it was just about the only one I could find in stock. Learn as you go I guess! I think I'll go with an adjustable gas block. It would be cool to have a rifle tuned for shorter cycles - just want to make sure it's also reliable and not a pain to keep running. |

| Im running the the same BCG in my rifle. I chose to go with and H2 buffer so the cycle rate would be slowed a little. With this BCG and an H2 buffer your looking to gain an ounce or two more over the standard setup. I haven't experienced any problems thus far. I have never tried running this setup with the standard buffer but I doubt you would have any problems. I just chose to go that route because I wanted the weight of the buffer and BCG setup to similar to that of an M16 |
| The buffer and BCG move as one unit. If you were to buy the lighter BCG and I heavier buffer you would in theory cancel out any change that might have taken place relating to weight. I wouldn't even consider the weight difference between the standard and Young lite BCG to be material anyways. The Young lite BCG would be considered super heavy when compared to some of the other Race Gun BCGs on the market today. |

Not arguing, but it's curious that you spent the money on the lightened BCG and H2 buffer when you could have puchased the M16 BCG to begin with. Especially since you say the weight difference is insignificant.
Also, the M16 uses a 5.2 oz buffer, and M4 uses a 4.6 oz buffer. (H2 per Colt IIRC) Seems that you would need an H3 or 9mm buffer depending on the weight of the lighter BCG. I know they move as a unit, but there are more physics in play there. Aren't those BCG's more prone to hydrogen embrittlement as well? |
| Exactly. I like the chrome bcg's and short of spending every waking minute on EE for someone to post a decent BCG, PK Firearms deal seemed pretty good since it was in stock for immediate shipmment. What it seems I should be taking from all this is that it may work just fine as is but an adjustable gas block would help tune things out. And, if all else fails a heavy buffer could be used as well. Both of which can be readily found too. Thanks for all the responses, and any more to come! |

Aren't those BCG's more prone to hydrogen embrittlement as well? I guess the risk of hydrogen induced cracking would be greater because of the chrome plating process. However, I have never heard of one of Young's bolt carriers failing because if this. If your worried about that then I guess you shouldn't buy any parkerized barrels as well. |

I believe he bought the lightweight because it is all that is available. Have you tried to buy an M16 bolt carrier group lately? There aren't many to be found. I guess having a lightweight is better than having none at all. FYI, I was referring to 40cal's posts rather than the OP. My bad. |
