Question for those with the RMR-style sight on their Glock GBB, I am assuming most are not using RS RMR, how are the ACM clones with the cycling on a GBB? GBBRs been known to just destroys some of the cheaper aimpoint/eotech clones, I'd actually think a pistol in most cases is worse since the sight actually are moving with the moving parts, where as on GBBRs are just a shake....
