[ARCHIVED THREAD] - Upper and bolt problem

Posted: 8/21/2008 7:59:35 PM EDT

I just bought a LMT 16in upper from Bravo company and my Lmt bolt or charging will not go all the all in the chamber. It ticks out about half a inch. What do I need to do? Is this somrthing I can fix or do I need to send it back to Bravo Company and get it replaced?

How familiar are you with the AR system?

I only ask because I don't want this to turn out that the dust cover is closed and you're not pushing hard enough.

I just CLP real good and pushed real hard and it went in. I just didnt put enough lube in the first time.

You shouldn't need ANY lube to get it to close by hand, with little or no force. Sounds like either the gas tube isn't quite centered, or the barrel is just off center enough to have the edges of the locking lugs hitting the sides of the barrel extension lugs on the way in.

It should just fall into place. No force required.

Should I be worried now? after I lube it its works fine real smooth. The bolt sides back and forth fine now

New gas rings can cause the bolt to be pretty tight in the carrier. I usually hand cycle a new bolt group a bunch of times if the bolt feels really tight, just to help break the rings in a bit.
