00053 here is the accu strut. there seems to be a lot of dodads to make the mini 14 shoot better.
The Original Barrel Strut for Mini-14s
I have seriously considered making a strut for a light barrel light gun build. i was thinking of making a gas tube that ran forward to the RSB you could maybe but a flash light or lazer in the front portion.
a strut running from the bottom of the RSB through the GB and forward to the muzzel could be done also.
Im thinking a heavy barrel that is flutted would give the same results. it would be easy to make up simple strut with some barrel clamps and try it with the hand guards removes on a standard barrel. Making the tension adjustable might give some results as well.
there are also tension barrels out there for various fire arms that possably be used on the AK.
