I have a Gracoil with LOP adjustment new for sale, I bought it for a gun than decided not to use it. Model # GC15 LP
Same features as the standard GraCoil, but with the added feature of "length of pull" adjustment, which allows adjustment up to 1". MSRP $240.
If interested I will let it go for $200 + Shipping. I do have also a new KickEez pad for it $25.
