These guys are great professionals, very open and friendly. They replaced the factory sights on my CZ 75D PCR with Meprolight while I was waiting so I didn't even need to leave my gun with them for a week or so. Nice job, very professionally done. It required some additional steps because the new sights were not a perfect match, but everything worked as expected. They even stayed for 30 minutes later to finish what they started and return it to me. I will test the gun on the weekend, but I guess there is no adjustment required, looks pretty much centered in my mind.
