Guys,
I was reading a report from the 60's or whatever on the HK G3 a while back and something in the report raised a question. Basically the report said that one of the contributing factors to the HK's reliability was that the bolt group had a lot of available overtravel before the carrier hit its rearmost stop. This allowed the rifle's mechanism to deal with shot-to-shot cycling variations within the stroke available to the buffer spring and thus not experiencing bolt bounce (or it would remain 'on the spring').
What this has to to with AR's is that if one were to use a heavier carbine buffer with a rifle length spring in a rifle buffer tube I would think that this would have the same net effect as outlined in the HK above.
This might necessitate having to shim the buffer spring (I would guess at the back of the tube) to get the correct installed spring height, but so what 5 min on the lathe to make a shim.
What do you guys think?
Anyone played around with something like this?
