Just got the PS90 (no rails) and I am interested in changing the factory optics to something more desireable.

Being new to this firearm, I am kind of in the dark as how to proceed. Looking for an all weather decent optics sight that will not cost an arm and a leg.

Is it better to get a rail and mount it to the rail or to replace the factory sight?

Kind of like the holographic - but thats an arm and a leg.

Soooooo many questions and not enough knowledge.

Thanks

Well, many companies sell the optic rail - 1 of our sponsors, MPF has the optic rail for the cheapest price I have seen. But, there are many rails available.

I have an EOtech, and I love it. Some prefer Aimpoints, That costs a bit more. There are some here with a Dr Optic - a small red dot. If U don't wanna spend in the $300 range for an EOtech, or over $400 for an Aimpoint or something else, there are some decent red dots out there around the $100 or so mark.

Which of these rail systems is the better? The single rail on top as seen at the MPF web site http://mpftech.4gunlovers.com/index.html?182.html&1 or the dual rail side system seen here http://www.halomfg.com/Details.cfm?ProdID=25&category=5. I have a weaver mount laser system and I will mount some type of holo sight as well. I guess that if I want to mount more thanone item, I will need two rails. Does MPF make dual rail systems for the PS90?

The 'simple' red dot sights are out for me. Don't like them, never did.

I was looking at the Bushnell with the weaver mount (I am told that weaver mount will fit picatinny rails but picatinny mount will not fit weaver rails) here: http://www.riflescopes.com/products/530021/bushnell_holosight_xlp.htm
This also looks more like a red dot.

I hate to spend the money on an EOTech but I guess that is the price one has to pay for a quality holo system. Who else makes holo systems besides EOTech and Aimpoint?

TIA

I have an optic rail (top rail) from Magazine Parts, and two of their side rails (1 on each side).

Now, MPF sells a similar rail to the one I have for less cost. He also sells side rails.

In addition, another sponsor here - Critical Dimensions - sells side rails and some other accessories. he doesn't yet have a website, but he sells stuff thru his forum here.

I personally prefer the side rails and optic rail to the tri-rail (1 piece with all rails connected)/ But, it can really be a personal preference. The tri-rail sits a tiny bit higher than the standalone optic rail.

U don't need side rails if U don't plan to attach anything. Or, U can just get 1 for 1 side. Or, U can get two - just for looks, even if U don't use them. Up to U.

Pretty much +1 to what Shipwreck has already said. You have a number of options for changing out the optics on your PS90. However, be advised that any optics setup using a replacement optics rail is going to sit significantly higher than the factory sight, thus reducing or eliminating cheek/chinweld if that's important to you (there is a new custom mount for the PS90 that costs about $100 that's made specifically for the mini-ACOG or the Aimpoint only that mounts them as low as the factory ringsight). The Eotech is an excellent combat-proven optic, is the first optic I had mounted on my PS90's and is very fast on target. I comes w/everything you need right out of the box (ie: no mount to buy unless you want QD like the GG&G Accucam) and is significantly cheaper than the Aimpoint. Unfortunately it sits signifcantly higher than the Aimpoint and other tube-style sights and the rear-facing buttons aren't as fast/easy to adjust brightness as the Aimpoint's (and other's) rotary controls which is why I eventually switched to the Aimpoint CompM4. You can get the Eotech 512 (uses AA batteries, appx 1,100hrs runtime on a fresh set of lithium batteries) for appx $300 if you shop around. HTH...
