I don't know this for sure but I have read elsewhere that although the swap is easy, there could be warranty issues with some limb companies.
Makes sense with he way liability is these days but does anyone know this for sure?
If it were me, and I decided on the Dalaa, I would just use their limbs. If I wanted the ability to swap limbs of different makers, I would get an ILF riser.
I guess a good one to ask would be Wingnut, seeing that he makes them. If I bought a set of limbs from you and and I switched the bushing myself and then had problems such as the limb butt delaminating, would you replace them?
