Colt LE6920 Question

Well I just recently acquired a Colt 6920 that I haven't had the chance to shoot yet.

Just today, I was messing around with the action and something unexpected happened when I had the bolt locked open. When I pulled on the charging handle, I only had to pull about a quarter of the way back and the bolt was automatically released. Now correct me if I'm wrong, I thought that wasn't supposed to happen until you pulled the charging handle all the way back. This isn't my first AR and that's never happened before.

Are you sure you didn't bump the bolt release in the process? If you locked it back by hand, the bolt may not have been caught on the lock tab correctly, and it released due to you moving the rifle. I've seen that happen when the catch snagged on the bolt carrier face, and not the bolt face.

I'm pretty sure I wasn't anywhere near the bolt release, but I'm not 100% on that.

Whatever it was, I can't duplicate it.

See if you can intentionally get the bolt catch to snag on the front of the bolt carrier itself (ie: between bolt and carrier). If it stays there for a moment, give the whole thing a quick shake, and it'll probably let the bolt slam home. That's probably what happened to you earlier.

It is also possible the bolt stop was barely engaged. Ask my middle fingernail how I know

I was inspecting the chamber for cleanliness when the bolt went home on my finger. I know nothing manipulated the charging handle or bolt release.

Thanks for the responses guys. Whatever happened, it must've been user error because no matter how much I try, I can't get it to do it again.

But if anyone else has any ideas on what it could've been, by all means share. But I think WoodenPlank may have hit the nail on the head.

Was there a magazine in the gun or not?

Magazine was removed.

I do have to ask before I let this thread die, is it even possible for this to happen if the bolt catch is fully engaged?

Assuming all parts are in spec and no operator error involved, it shouldn't be.

I'll be taking it out for the first time either this week or next and I plan on putting around 250 to 300 rounds through it. If I go through that whole shooting session with no problems, can I go ahead and assume all is well?

It depends on what kind of problem you might face. Plenty of AR issues are magazine related, and have little to nothing to do with the rifle itself.

For me, I feel I can trust a rifle after I have run a minimum of 300 rounds through it, including different types of ammo, and whatever I plan to feed it as a HD/SD load.
