Carrier Replacement

Of course, after you’ve put a good number of rounds through an AR, it’s not a good idea to seperate the Bolt and the barrel extenstion/chamber that have got to know each other well and have worked in (unless the bolt breaks:mad:). What about the bolt carrier? Is it a bad idea to replace the carrier? Is seperating an upper and carrier a bad idea after they’ve worked in? Will it effect anything? I have about 1K rounds through an AR that I’m considering swaping out the BC.

I just got a complete EXO Coated (FailZero) BCG from Spikes. I was going to use it on a new build, but I’m thinking of replacing the carrier with the new EXO coated one I just got. Could this cause any issues?

PS: I’m really interested to know if this could cause accuracy or function issues. Please don’t post something like “fancy finishes are crap, forget the EXO.” etc. Thanks.:smiley:

There is no reason to swap the BCG. Aside from a failure of the carrier key, it will probably last a lifetime.

I agree with Iraqgunz. The carrier should last a lifetime unless the key breaks. Of course regular maintenance is required to remove the buildup of carbon in the carrier.

Dropping in a new carrier is fine and should not create any issues. Interchangeability of parts is needed for mil type weapons- of course working under the assumption of in-spec, quality parts. As correctly stated earlier, bolt carriers rarely need to be replaced due to wear. However, I have swapped out a few older non-shrouded carriers for full profile shrouded ones.

FWIW, the Spike’s Tactical nickel-boron coating is different than FZ’s.

Go on…

Something about the % of nickel or boron or something in the coating

Bolt group coatings are just a big waste of money at any “% of nickel or boron or something”. About as affective as painting the backside of drywall…

Disregard my comments about Spike’s.

It was a previous coating. All current nickel-boron finish BCG’s they sell are done by FailZero.

Based on what?

There are more important things to spend money on in an AR15

If you were constantly operating in a maritime saltwater environment, I would say a coating on the BCG would be fine but otherwise…

It’s a niche product. As I stated in my review of the FZ, the real advantage comes when shooting suppressed or FA SBR’s. Nothing eats lube quite like a suppressor.
So, even if it doesn’t apply to you (‘you’ being the collective ‘you’, not individually), it doesn’t mean it’s a, “waste of money” or, “worthless”.

Even with a regular old AR, it’s kinda nice not to have to lube for extended periods of time.

Too funny. Did the NiB haters read my entire initial post. I could say a lot for getting a NiB, but that’s not what this thread is about. If you want to bash NiB then start a new thread.
