Picking up a PS90 next week, exploring optics and a lower profile mount. Currently it appears that HB Industries has the best "system" for the mount and sling mount. *Thoughts on what optic-possible the Acro or Steiner-feedback on those? No experience with them. *509T-same as above. *Aimpoint Micro and using a Holosun 515 series. *This is not about FRT or SBR--- Thoughts? https://hbindustries.net/shop/fn-p90-ps90-low-profile-optic-mount-trijicon-holosun-aimpoint-dpp-vortex-canik-burris/ |

| Excellent! I actually went by the shop, looked at the Holosun ARO, going to get that instead along with the HBI mount, the ARO is micro footprint. Unless I'm missing something, the DM does not have a sling mount to mate with the optic mount. They should since it shares the same holes. |

I like the DM attachment but they don't offer the sling mount like HBI-then I wonder if I simply use the longer screws with the HBI mount and into the DM mount? I'm going to simply go with the HBI so I don't have to worry about filing, sanding, re finish etc if the DM is tight. Initially was concerned with how the HBo attached then realized the factory attaches the same way-- Again, I find it odd that DM doesn't offer a sling mount to go with the optic mount-other than the method. |

I did order the HBI Micro from FN Specialties, arrives Sat I hope. I should order the sling stuff later and then decide on the SBR stuff. |
