Purchased the Brownell's ejector removal vise and practiced removing the ejector on a spare CMT bolt I have - it was easy (and kinda fun) especially since this bolt is a spare, not being used, clean, never fired. But I'm a little bit nervous about taking the punch and hammer to one of the bolts in use that has several hundred rounds of crud around the retainer pin.
Does anybody remove the ejector for cleaning? Is it necessary? How often? I'd much rather leave it alone and not find out how fragile those 1/16" punches are !! |

This is the ejector you're talking about and NOT the extractor?
The little round spring loaded thing in the front of the bolt,. not the hook that catches cartridges for extraction? I've never heard of anyone removing the ejector for routine cleaning, nor have I ever seen this mentioned in any manual I've read. Replacing the ejector if it' jammed or broken, yes. For cleaning, no. Now the extractor gets pulled every time the rifle is cleaned. BSW |

Removing the ejector is easy IF you have the right tools. Here's what you need:

Thanks for the replies. Fact is I have an LMT bolt that had the retainer pin sticking out about 1/16" as received new. Didn't notice it until I went to clean it after about 100 rounds. When to smack it back in but with no success - I bent the punch and the pin.
Well, I'm embarassed to say the least. But what is ISO 9001 good for if they (LMT) can't prevent this BS from leaving the dock. Purchased a new punch from Brownells and gave it one good WAMBO hit and it finally came loose. Then it was difficult getting the new pin in. The learning curve is prooving longer than expected for this task. Will take your advice - I will leave it alone as to not let my tinkering addiction get the best of me !! Regards, |

I picked up two used USGI bolts as spares. I added BCM Extractor springs, inserts, and new gas rings.
I took the Ejector and spring out just to make sure they weren't rusted, then lubed and reassembled. I've never heard of anyone replacing the Ejector or spring, but I have a few on hand in case I break one.

its hard to remove because the spring tension is holding the pin,
you dont need special tools other than a vice and a punch, bolt face against vice and tighten, punch pin out, release vice, reinstall is the same spring in , ejector in (correct way) slowly compress ejector in vice and install pin. |

It's not a big deal. I'm not seeing why you think it is? Special tool? Not needed. Most clean them every 500 rounds or so. Some every time they clean, some never. Does arfcom have an ignore user feature? No, I would have used it after reading this. http://www.ar15.com/forums/topic.html?b=3&f=7&t=488215 |
