I ordered a Young Manufacturing Black Phospate AR15 BCG complete. I got it in today and the craftsmanship looks A+, but the gas key screws are not staked. This is the first Young BCG that I have ever held and was curious if they don't stake their carrier key screws from the factory. It does not bother me, I know how and have the tool to do it...I just found it strange that an "upper end" manufacturer did not send it out the door with the carrier keys staked.
Anyone else get a Young BCG that did not have the gas key screws staked? |

Quoted: Young never stakes his BCGs. He recommends not staking them, but uses an extra strength, high temperature thread locking solution instead. Has anyone that uses Young BCG's ever kept theirs NOT staked and had a problem with them, i.e. Should I follow his recommendation and NOT stake it? |
While I dont believe you need to over-do it, I'd definately have some kind of staking on the key, to where at least it's touching the screws. That said, as long as theres NO staking, you might as well give it a decent job. Dont go with only locktight. See the sections above for the how-to.

Young uses red locktite and that's probably ok if you never push your rifle hard but if you do, the locktite will break down under high heat.
It is a good idea to stake it. I bought both of mine from Rainier and they staked them. A friend bought one from Steve (Young Mfg) and had no problems for several thousand rnds until he took a carbine course. He made it almost through before one screw came loose. Hope this is helpful C |
| I believe most of the distributors that sell Young's products stake the keys (Spike's did on mine). This argument is both long and old. I do sense from the number of threads I see related to this subject that there is too much emphasis on a relatively simple task. Stake them, don't stake them, Loctite them, whatever gives you peace of mind and performance. There just seems to be too much written on this subject in my mind. I've seen hundreds of thousands of rounds go through these rifles and have only seen one key ever loosen up, the owner put a couple of new fasteners in, torqued them and moved on that's what needs to happen with these topics. |

I purchased a Young Mfg. Bolt Carrier Group (BCG), from a rep. at Puyallup WA. gun show. It seems deferent from other BCG's, I've seen or owned. I've been shooting M16's and it's variants since 1975. Now just AR's. Seen lots of BCG's.
I was just this week putting together two 'carbines' and dropped in the BCG's and cycled 20 times. Tested function check, oiled everything up and repeated process five or six more times. each. Had glued in pad on receivers to prevent hammer from contacting firing pin. Took apart to inspect each. This is what I noticed. The carrier key looks as if the left surface was done with a surface grinder. It doesn't affect function but it looks...odd. Never seen this before. Does not appear to be machined. Key is not staked. More of a concern is the Carrier itself. The bearings surfaces are narrow. <.080". Compared to Colt .117" to .122", checked some friends BCG's. None was less than .115". All surfaces were approx. 50% wider than the Young BCG. |

Ordered the same BCG as you and mine didn't come staked. It seems if you order from a vendor (Rainier and PK come to mind) that they'll stake them. This. Quoted:
