CETME Buffer

[drhall762]

Now that my parts are disassembled and cleaned up, I need some more information.

What composes the buffer? Is there a spring in there? How does it work? Can it be disassembled?

:thanks:

Yes, it can be disassembled. Look at this website that sells replacement buffers. They have a nice diagram.

I bought one of those Blackjack replacement buffers but it's still in its little baggie. I tried off and on for about a year to get the buffer apart to replace it. I never was able to get it apart... Lots of penetrating oil, torque, tools, hammer blows, heat, cold, and emotion...decided the original was OK. :wallbash: Maybe I should shoot some Indian ammo at it. I understand it blows things up.

I didn't have a problem with mine...but I see Dr Zero used this method.

Taking the buffer housing apart can be kinda hard but a clever tool was designed by a CETME Forum member here is his instructions.

I used a 5/8 castle nut. I used a piece from the end of a LARGE mending plate I had kicking around for the bar part. I pressed it into the castlations on the nut, then cut it off so it was only about 1/4 inch taller than the nut face. A bit of dressing it up with a file insured that it fit the slots in the back of the buffer and was flush with the sides of the nut.

I locked the plate of the buffer assembly in a bench vise, then set the new tool into the slots. This let me put a 7/8 deep well socket over the whole assembly and use a 1/2 in. drive ratchet to turn the plug out of the back with darn near no effort at all!! Replaced the old rubber buffer and reassembled with the same tool. Job took about 3 minutes with the right tool. Hope some of you guys benefit from this.

Thanks for the info. Life is good.

Getting mine apart was also a nightmare and I'm not at a loss for tools and methods. Whatever Century puts on the muzzle brake threads, they also put on the buffer tube threads. After all the trouble I went through getting it apart, I wound up shortly thereafter going with a G3 buffer assembly when I changed to a G3 stock. I did toss the bronze spring assembly and put a BJB replacement in it and it did improve perceived recoil on my behalf. I highly recommend the BJB replacement.

I'm not familiar with this "BJB buffer replacement"

can you tell me more or post a URL?

we just did Steelcore, BJB=blackjack buffer...the link at the top.

My buffer came apart trying to unscrew the rear bolt! Now I'm fighting to get the buffer end cap off of the bolt, because its still stuck!:o

[Hoot]

Can you reach the buffer end cap so that you can oil it up? Does it protrude far enough from the stock to get it in a vise? That's a heck of a pickle!

I split the stock completely into pieces. I now have the screw and cap soaking in Super-Pen.

Good thing stocks and such are cheap for these puppies right now eh?

[WildBillCody]

That's what I had to do to one also.

I used a 4' long piece of angle iron with assembly in a vice. Put it back togather that way too.

[97th Signalman]

Yup, I tried the special socket tool and the angle iron tool. I Bent the angle iron without budging the buffer plug at all. If I didn't know better I would swear it was welded in. Maybe the monkeys used permanent Loctite. I have given up and the Gun shoots just fine.

[drhall762]

As with everything I find rust on, I soak it down with PB. 24 hours and it comes apart fine. Used it on the stock bolt and the buffer. The castle nut idea worked great.

Sorry, I had a 'hi-density moment' there...right. BJB=BlackJack Buffer.
