This mount will accept the T-1 / T-2, the Vortex Sparc ll, and the Romeo-5, and the ACSS Cyclops by Primary Arms.
For people battling with astigmatism the ACSS Cyclops by Primary Arms is what we recommend, due to it being an etched reticle and reasonably priced. As a bonus it also works with our FX3 3X Optic Flipper!
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.
Please note that FN casts their receivers for the P90/PS90 so the tolerances within the receiver are like snowflakes, no two are identical, and can be tens of thousandths different. Thus fitting a precision part into said receiver will have varying results. If your mount happens to be extremely tight (to the point of beating it in with a hammer), give us a call and we will shave down the sides/repaint it for no charge.
*If mounting a Sparc II Vortex please E-mail (Dmachineri@verizon.net) after ordering as the recoil lug for the sparc is slightly different than the Micro adaptation. We've solved this issue with a small attachable aluminum piece, precision machined to sit on top of the mount's existing recoil lug. You do not necessarily need this adapter, but it makes it much more stable versus not using it.
*For a bead blasted, unpainted product, giving you the ability to paint it yourself, we provide this product 10% off. Use discount code "NOPAINT" at checkout. (Product will come sand blasted and unpainted).
