I notice a lot of the high end uppers built by vendors and indivduials use the Young NM bolt carrier assembly. What are the advantges to using these rather than the M16 or AR 15 enchanced carriers? Easier to clean?

DPMS also has a chromed bolt carrier assembly as well for a few bucks less. PK Firearms has these in stock and I'm so tempted to order one to try out.

Wes,

How's the quality of the Young chrome plated bolt? Are they MP tested and how well are they holding up from breaking at the cam pin hole?

Lastly, is it true that Les Baer BC groups are made by Young Manufacturing?

Wes,

Is that the MOACKS?

Wes,

I just read Pat Rogers article in SWAT on staking keys and I could have sworn he quoted a higher torque value, something like 50-58 inch-lbs IIRC. I also recall he quoted a TO on staking procedures, I assume that's where he got the data from.

Are you sure the number you quoted is correct? That's a pretty decent difference. Just curious.

Wes,

Thanks for the info!

BTW, what bolt do you use with the Young Manf. chromed carrier?

I HAVE NEVER USED THEIR BOLTS, MYSELF. I AM CONFIDENT THEY WOULD BE TOP NOTCH, HOWEVER, LIKE EVERYTHING ELSE Y/M MAKES.

CORRECT - YOUNG MFG ORIGINALLY DESIGNED, PATENTED, AND NOW MAKES THE LES BAER CUSTOM BOLT CARRIER.

Do you sell these still Wes?

How much am I looking at for just a chrome carrier, be it young or les baer marked?

Also, I seem to recall these carriers are lightened ... this true?

WE SELL THE Y/M NAT'L MATCH CARRIER FOR $145 AND THE LES BAER CUSTOM FOR $195. BOTH ARE FULL M-16 WEIGHT.

YOUNG MFG MAKES A LIGHTENED VERSION WE USE IN OUR COMPETITION UPPERS. WE DO NOT OFFER THAT CARRIER SEPARATELY.

VERY OBSERVANT. YOU ARE CORRECT.

Thanks. I'd ask you if they weighed the same but you really should be building rifles instead of answering some PITAs questions like mine

Just add the cost of a Bolt and you have a ballpark figure..

Wes,
I've always been curious what exactly a "fitted bolt" is. Has it indeed been fitted by removing material from an oversize part for optimal dimensions relative to the mating barrel/chamber (I'm thinking NO, since we're talking mass-produced CMT/Stag or LMT parts here)? Or, have multiple bolts perhaps been precisely measured and dimensionally categorized to mate with barrels/chambers within corresponding tolerance zones? I assume (something I hate to do less it make an a$$ of me) that we're not talking simply go/no_go checks here. Please elaborate if you can.
Thanks!

Do either of these companies make a full auto version of these bolts or are they strickly for semi rifles?
Link Posted: 10/23/2006 9:53:46 AM EST
From my limited understanding there is no difference in the bolts between the AR and M16. As to fitted bolts, I know BigBore has posted before that when he recieves 10 barrels from WOA that he also gets a bag of 10 bolts. They are not fitted to one particular barrel.

Then what would they be fitted to? I'm not trying to be a smart a$$; it's just that this doesn't seem logical to me.

What I meant to say was; Do either of these companies make full auto versions of these bolt carriers? Or would the advantages of the carrier be lost on a full auto weapon?
Link Posted: 10/27/2006 9:11:05 PM EST
I too have been wondering about the "fitted bolts". My roommate just received his Denny's Recon barrel with "fitted bolt" but it looks pretty ordinary to me. Just like any other MPd Stag bolt out there. The receiver extension looks just like any "4" marked receiver extension out there.

On the YM bolt carriers, the same roommate just got one of those too. It looks incredible. I basically got wood when I held it. The machining is top notch. I'm thinking of switching to some of these as well.

I had pretty much dismissed all super-dooper chrome plated carriers as a really bad idea. Supposedly the US Armed Forced quit using them and took them out of service during the Viet Nam era because they were found to cause excessive and premature wear to the forged aluminum uppers. Is this not so or is there some reason the Vietnam era chrome plated arriers caused this problem that has been somehow addressed with these carriers?

Does the chromed carrier aid reliability because of the chrome's innate lubricity?

Wes, how do feel about Robar's NP3? I was thinking of getting one of the BCs in discussion and then getting this treatment done. Do you have any experience with it?

I am theorizing the parts required for the ultimate reliability in a DI carbine.

You gonna stake that carrier key?

Thats the one big reason i havent bought one yet. Maybe after i get a MOAKS.

at the time i bought it, ~ 2002, Young was using red Loctite on the key. it certainly hasn't moved in about 2000 rounds. nevertheless, next time i send off some parts i think i'll get it staked -- just in case.

After shooting about a thousand rounds at the last AZ Big Sandy MG shoot through my MRP with a chrome carrier supposedly made by Smith Enterprise (has a D stamped on it, DMPS ) and an LMT chromed enhanced bolt, I agree it's easier to clean.

I let a friend borrow a Colt carrier and bolt, he shot as many rounds as I did through his in full auto. Since I got to clean both carriers and bolts, I had an impromptu side comparison.

During the shoot, the chromed carrier and bolt continued to function smoothly whereas the Colt carrier and bolt seemed to start to drag a little. I sprayed some CLP on the Colt unit, didn't touch the chromed b/c. The chromed parts were easy to take apart and clean, I had problems pulling the Colt bolt out of its carrier.

I'm a believer of chromed b/c now, and in the process of replacing most of the b/c with chromed units. So far I have a tried and true Smith Enterprise (or DPMS ) carrier, a LB carrier made by YM (haven't shot it yet, but it's smoooooth inside the Vltor MUR as though it was rolling on ball bearing), and just ordered POF's chromed b/c

Was gonna take the LB/YM carrier to the Big Sandy shoot, to my dismay, I realized it wasn't a full auto carrier Does YM make a full auto carrier?

A buddy of mine used one of these (for the record, not purchased from MSTN) in a recent custom build with a CMT M4 upper receiver. The sucker was so tight, the rifle wouldn't function well at all for about 100 rounds. The carrier just wouldn't freely move back and forth in the upper.

After about 100 rounds of ammo, gratuitous amounts of lube, and some serious hand cycling, it finally runs well enough to actually use.


After his experience...I certainly wouldn't buy one.
