Young Manufacturing Bolt Carrier Group

So I bought this AR-15 BCG directly from YM. Its their chrome version but not the national match unit. It cost a fair amount more then its milspec counterparts but was only slightly more then some of the best like LMT. Holy cow is this thing an example of machining perfection and beauty. Wait until you see it!

heres a few quick pics

That does indeed look top notch!!

From the first pic, it didn't look like the gas key was staked.  Can I see that area close up?

[Microgunner]

Yep, the second thing I noticed also, after the high quality appearance.

Ill post later why it is not staked

Damn, they're pretty adamant about that. I'd stake it anyway after permatexing and torquing.

[imschur]

Well this is going in a paper puncher so Im  going to leave it as is and see how it goes

We stake them at work, just to quell the masses that insist on staking the gas keys. My NM Young BCG is not staked but is Permatex'd, torqued to spec(60"/lbs)Loc-Tite'd.  ;D

[imschur]

I think that the correct torque and the loctite are the key to  YM's process. Perhaps if the spec was written today with the availability of modern thread lockers the spec might read different.

The other side of the argument would be heat. Is it possible for the BCG to get hot enough to neutralize the loctite? I would think if that was the case the barrel would be on the verge of a melt down.

Interesting stuff for conversation

I've had them barrels hot enough to make grilled cheese sandwiches on. Smoking the oil off.

Having spent 21 years dealing with Mil Specs, I can honestly say the military will almost always go one step passed what is trully necessary. Everything has a torgue and very often we had to mark across set screws with a marker or stencil so anyone looking at the item after assembly would know the screw hadn't loosened.

I ordered a NM this time for comparisons sake. You guys are just as expensive to hang with as my guitar friends  :confused: :swars:

[Microgunner]

Hell, it's just green paper til you convert it into something you need or want.

[imschur]

Heres my latest, a stripped Young Manufacturing carrier. It a stripped National Match to mate up with the  bolt and barrel I bought from Ranier Arms.

Playing with a new lens so you all have to put up with pictures  ;D

[Microgunner]

Damnation that's pretty.
