Cool. That is a good price. I was just thinking the other day about getting one of your super bolts and having FailZero treat it (don't know if they'd do it). I love my Spike's Nickel Boron BCG... would really like to have one of yours.

I get the coating makes it easier to clean the bolt but the carrier is what moves around the most and would benefit most from the coating IMO.

How do you think they compare to the chromed ones? I like how easy the chrome cleans but black is better IMHO....

These are a dark silver/ light charcoal color, they are a little slicker than chrome as far as sliding through the receiver and should clean just as easy.

I think the lubricity of the NB coating helps the bolt functioning... (as well as the ease of cleaning). I've seen a function test of the FZ BCG where there was no cleaning/lubrication done over a 4 day period (two very high round count rifle courses). They had no failures attributed to the BCG during those two courses. Not a big deal for plinking, hunting, etc... but good for a SD/fighting rifle.

Helping the carrier slide back and forth in the receiver I can see, very little of the bolt touches the carrier, the 3 gas rings and a small band .080" wide just behind the extractor pin.
The NB carriers combined with Mobil 1 or the machine gunners lube is a very slick combination.

Oh... okay. Thanks for the info. I thought that the bolt had more contact with the carrier and the coating would help as the bolt rotated in and out of the carrier. That's one reason why I keep coming here... to learn new things (or correct misconceptions).

I'm using wheel bearing grease at the recommendation of an instructor... but I've heard a lot of good things about Mobil 1.

H, how do these Nickel Boron BC's compare to the Nitro-carburized (melonite) BC's?

Nickel Boron is apx 45-50 Rockwell, Nitro is apx 70 Rockwell and the AlTiN coated carriers are 90 Rockwell. The NB carriers are the slickest and why most want them, fail Zero has done a lot of advertising promoting them.

Thanks H, NB sounds like the way to go, especially if you don't want to run a really wet gun. I sent ya'll an e-mail this afternoon requesting that the Nitro-Carb BC in my order be changed to your new Nickel Boron BC.

BTW, do you have a thread that you post status updates to regarding the ETA for the next shipment of barrels & bolt carriers? Can't wait until your next batch of 6.8x43 16" Nitro Carb barrels come in!

I don't have a thread but, I'll bet it's mid March before we see them.

H - I taked with Donna last week and ordered a 18" 68 x 43 rifle from you built using a mega monolithic upper and piston.
Can the carrier used with the piston system get the Nickel Boron coating?

No, those carriers are one piece and come from Adams Arms.

OK - I didn't know if you were having the Nickel Boron coating added or not.
Would there be another option to upgrade the Adams carrier similar to the NB - or am I just spinning my wheels?

Thanks!

You could sent it out to Ion Bond, the batch prices on other coatings is high $500 for Nitro or PVDs.

We buy the carriers NB coated.

Any of the NB coated carriers that are sterile of the 18186 or other markings?

Gotta ask a real stupid question constructor. Do they all have the 18186? I got a 18186 in the mail today. Thanks! looks good in the upper. I guess it's going to be mid March for the barrel. I still need to gather up mare parts anyway to complete the build. Looking good so far! Thanks again.

Yes, must be a lot number or manufacturers number.

In you opinion constructor is the NB coated carrier better than say a Young Manufacturing Chrome NM Bolt Carrier? The reason I ask is after looking over the Adams piston kit and its cost etc and the limits it puts on what rails I can use I may lean back towards going on a DI upper SBR using one of those bolt carriers, I have been told a 6.8 burns up more of its powder than 5.56 so DI in a SBR isnt as big a deal. Also when do you guys plan to build SBRs again? I see it on your site but their is no options listed on them. Also please to hear your using Mega recievers now.

Most chrome carriers are decorative chrome not hard chrome like on the inside of carriers so yes I think the nickle boron is better. We can do SBRs any time as long as the use the same mid length gas system which means 12" barrel or more, it is a $65 option to cut, re-crown and re-thread, just need to call the office for that one.
