This mount will accept the T-1 / T-2, the Vortex Sparc ll, and the Romeo-5.
This system is very rugged, made from 6061-T6 aluminum, and machined to fit the sight angle as well as the receiver angle. These angles are very important although most of the time over looked. They provide a much better contact point so it stays tight and true. The receiver is a casting and needs a 1 deg. wall taper to release form the mold, if you don’t machine this into the mount you’re not going to get a proper fit.
The dot itself is as low as it can go, providing a great cheek weld, very fast on target, as well as pinpoint accuracy. I still would go with the RMR for Secret Service, CQB work, kicking in doors all day, etc.. But for most guy’s the T-1 / T-2 is the way to go. It turns the P/PS-90 into a much more usable rifle with no comparison between sights. It’s something that needs to be held to appreciate.
