Looking for buffer assembly diagram

Hi guys,

I went to the range after work tonight to test fire my build and ran into an issiue. on the 6th round the rifle did not eject. I noticed this as the trigger had not reset. Going through drop the mag and pull the charging handle, I noticed that the CH would only come back about 1/3 of the way (not cool). Popped the rear pin and the bolt came out with an empty, no problem. As it moved around, there was a sliding sound from the butstock. End of range session.

Came home and removed the buffer (awful light). The buffer is in pieces on my bench now and I am wondering if there is a special order for the weights and spacers to go back in it. I have had zero sucess with google and our search. Please help.

Thanks

Get a new buffer. Once they are broke I don't think they are worth trying to fix.

Sounds like the buffer got stuck in the buffer tube??? Maybe the spring got hung up between the buffer and tube??

You may want to look at the whole buffer, buffer spring and buffer tube replacement......something might have been out of spec?

One thing I like to do is grease up the buffer spring.....keeps it quieter too (no SPRUUUUNG noise).

I am also going to assume that you took the buffer apart? if not, buy a new one, if you did take it apart.....the rubber discs go between the steel discs.

and for the most part.....you can NOT mix rifle buffer parts with carbine buffer parts (atleast not with out some extensive working knowledge of the whole interaction between ALL the parts involved.

Tim is right. Make sure you're not using a carbine buffer in a rifle length tube. The carrier key will smack into the lower receiver.

There should be a roll pin holding the buffer guts in. If that broke it would be a first I've heard of it.

Make sure you have all 223 parts or all 308 parts. Somebody told me they are different in the buffer area.

To answer your question..this is what goes in first and then so on. Long spacer, rubber washer, weight, washer,weigh washer...etc. lastly polymer buffer held in by roll pin throught the body of the buffer. FWIW I have seen buffer assemblies without the roll pin installed and they do just about what you describe. KurtM

Thanks for the info all.

Kurt, you are right about the Roll pin, there isn't one :surprise: ! Looks like it got past QA/QA and shipped. I called the suplier about my other post on Barrel weight and mentioned this issiue, and they are shipping a new one out first thing in the morning :cheers:.

Now, I am really glad that I put the new furniture and upper on my old(er) lower and gave it to my dad instead of letting him have this one.

How hard would it be to drill this one for a roll pin?
