Hi Folks

I have one of the long Delrin buffers for the gen 1 GSG-5 that I am going to install. Do you need to use any kind of glue to keep it in place or will it stay put after you put it on ?

Thanks

It should be a tight fit in the cocking tube, no glue needed

Thanks for the reply, I installed it and you are definately right it was a tight fit. I think something is wrong though. When i pull the bolt back and let it go the cocking handle is stopping about a half inch from the receiver and it is very hard to pull the handle back. I have to give it a couple good whacks with the palm of my hand to get it loose to pull the bolt back again. Is the buffer supposed to stop the handle that far from hitting the reciever and should the buffer/ charging handle be that tight and hard to pull back ? Do I need to work it back and forth a little to break in the buffer and loosen it up ?

Thanks

I have a delrin buffer in mine that somebody was selling on the EE last year along with screw kits. It is rather loose...I will probably have to shim it or something...

A quick fix for that is put the buffer end to end in a bench vice and tighten the vice as hard as you can.

But should the charging handle be about a 1/2"  away from hitting the receiver after you pull it back and release it ? I know you don't want the handle to smack into the receiver but that seems like a big gap now.

That seems a little far, but if there is still play in the charging handle spring before it starts to move the bolt back, it should be okay.

Your charging handle should not be sticking with the buffer installed though.

I'm starting to think this Delrin buffer is a piece of shit. First it is binding on the inside of the cocking tube housing causing the cocking handle to stop about a half inch from hitting the end of the slot and wedging itself inside the cocking tube so tight I have to take a small plastic hammer and tap on the cocking handle to break it loose so I can pull it back. So i take the cocking tube out and lightly sand the Delrin so the cocking tube/Delrin will now slide smoothly inside the housing, put it back together and now the cocking tube handle travels all the way and it appears that when it stops it is still making contact with the end of the slot. I didn't sand anything off the length of the Delrin, Is the length of the delrin cut that close that the post on the cocking handle should still come to rest against the end of the slot ? If you measure the post on the cocking handle to the end of the delrin it is 3" Any help or answers would be appreciated.

Ok just to clarify, when you put it back together you did put the buffer in the short side if you were to measure it from the cocking handle?  Is your rifle a gen 2 or 1?

Hi

it's a gen 1. It is on the short side, on the end going towards the end of the barrel.

I had about the same experience.  I wore mine down with steel wool until it would penetrate into the cocking tube all the way.  Then I worked it back and forth a few times.  It now closes, just like mentioned above, seemingly all the way up against the metal.  However, upon very close inspection, I believe it stops at something like 1/64 " from the metal.  The sound it makes when it stops is more lilke plastic on plastic as opposed to against metal.

I hope.
