Been reading the site for a while now. There is some very good info here.
My question is will a buffer spring from a six position tube work properly in the shorter 4 position tube. Or will it cause to much force to cycle the bolt carrier properly.
The amount of ‘stops’ on the receiver extension (buffer tube) has no correlation in relation to the buffer spring length. All CAR receiver extensions are the same length just as all the rifle (A1/A2) are the same length.
