AR BCG Failure to extract

[Tony617]

how does the charge handle look?

 

[Tony617]

Recommdations for my new BCG? I have a nirtride one from Spikes Tactical and I also have nitride BCM one too. I do have a Spikes Tactical rifle that I bought a few years now so I could use my Nickel Boron BCG in that rifle.

Personally I prefer nitride over NiBo anyway.

Do those other carriers cycle ok with the affected upper and Charge handle?

Sorry if it seems like I'm crowding your thread... It's an interesting issue that my OCD needs answered

BCM BCG has been flawless in my rifle. I strapped on a full-auto lower and it burned through 500 rounds with favorable results as well. Great product.

I have 18" chrome barreled upper that bought from Palmetto State Armory and bought a Nickel Boron BCG for that upper. I fired a little over 200 rounds with that upper with no issues at all.

With regard to my Spikes Tactical Nickel Boron BCG, shall I remove to rubber o-ring from the extractor? My BCM rifle does not have the o-ring on the extractor.

Just one more opinion .
Your getting too many opinions . You need to go through the process of elimination not just start guessing and accepting internet guesses .

 

[Mygrainman]

Make sure it was an issue with the bolt by trying one of your other bolts in the affected upper to make sure it will easily cycle.
Then try the suspect bolt in another upper to see if it doesn't...
Just be careful not to jam it in there and get it stuck.


Which ever BCG you pick, I highly recommend taking it to a Smith and having the headspace checked with go/no go gauges.

Thank you for all of the input people gave me. Strange that Nickel Boron BCG was undamaged. I put the BCM nitride one in instead. Also the BCM GFM MOD 3B was not working since charging handle way not letting the BCG go all the way forward. I am using the spare charging handle that I bought from Brownells instead.

Does this have an adjustable gas block? I had the same issues with a Palmetto upper with factory ammo not extracting and having to use a rubber mallet on the charge handle to open the bolt. Turned out to be way over gassed. I tuned the gas block down to barely lock back and all is good.

Seriously don't hit your charging handle with crap ....it's like the weakest most important part you know .

No it is a BCM low profile .750 gas block.

I run BCM and Fail Zero's.

Maybe I should have qualified what I meant by hitting my charging handle. I used a rubber mallet for setting tile and tapped on the handle a few times. With that said, I rather destroy a cheap charging handle than destroy any other part of my rifle. I realize this mortarizing is acceptable to some people, but we're not soldiers out in the field without tools. Smacking your butt stock against the ground put undue stress on the butt stock, buffer tube, and receiver. Don't motarize your rifle unless you absolutely have to

Mortaring an Ar should not hurt it one bit. The weak link will be the brass. If the cartridge doesn't extract it will just tear a chunk of brass off the case head. Julia Steel on the other hand, looks like she could hurt you. As always ymmv.

 

[titsonritz]

Be sure to fully collapse the butt stock. I don't think I'd want to try it on a commercial RE due the smaller thread engagement.

I took my repaired AR to the gun range today and fired 125 rounds through it. With my 3.5lb CMC Trigger it shoots very nice.
