    Thanks for that info. Didn't know there was a spring in A5 buffers, since I haven't been able to get my hands on one yet.

    One could also make a peice of proper length'd delrin to go on the other end of the buffer spring.

    I didn't really want to effect the preload of the spring, but I suppose it wouldn't matter all that much, especially temporarily.

    Putting a 3/4" long spacer under the spring is going to cause you mucho grief. Make the spacer go thru the spring, not under it, thus not compressing the spring.

    I've already done that using aluminum instead of Delrin. Works perfectly. I started with a piece of 7075, 15/16" diameter, 3/4" long, and turned all but 1/16" of it down to 3/4" diameter. The spring sits on the full 1/16" shoulder and holds it in the bottom of the tube. the rest of the spacer obviously goes into the spring. Then you can use any weight carbine length buffer you want. Been doing this for a couple years now.

    Because I have a 3gun match this weekend and haven't even shot my new rifle yet. Did I mention I was an idiot? Yeah...

    That's pretty much what I did, except I attached it to the back of the buffer. Didn't trust a screw alone to hold it at the back, so I screwed and cemented it to the back of the buffer.

    I like the aluminum idea though. How much for you to make me one of those? I have zero access to a mill or anything like that.

    I think you were saying this but I may have lost it in the sauce, the A5-1 has a tungsten weight with a dimple and spring then the rest steel. The A5H2 and 3 have the steel up front with dimple and spring.

    So far I have taken every one apart and recorded the data and illustrations of each, if you looked at my Data workbook and had no idea what a buffer was you would think I was a sicko.
    If it would be beneficial I will put together a good copy the data and send it to IG to do something with on here.

    Would you mind linking me to that?

    Yeah no problem, let me fix it up and put everything together first. I need to make sure it's ok if I do also, I do not want to step on anyone's ground.

    These are what we knocked out of 303 stainless on a CNC lathe for our own use. Carbine buffer that weighs between a H2-3, and a 6.175oz buffer to fit the A5 tube. We have run these with 5.56, 300blk, and 6.8 calibers with 9", 10.3", and 16" barrel lengths.
