Websymplectic bundles we prove that the smooth locus of M Sp 2r is exactly the set of regularly stable symplectic bundles (for r >2). This proof, which requires a precise description of bundles associated to points of the moduli spaces, cannot be extended to another group G without a good understanding of the nature of these bundles.
