Does anyone know of any other sight adjustment tools besides the FN tool and the MPF Tech tool?

I've heard U can just use an allen wrench and work it by hand. But MPF is the cheapest sight tool I've seen.

Are there simple DIY methods of making your own adjustment tool?

I have the FN one and it would be pretty difficult to make a copy of it youself.

But for DIY, all you really need is a allen wrench and a penny or a dime.
Use the allen wrench to loosen the hex screw then use either a penny or dime to turn the outer screw. Once its in the location you need, then use the allen to tighten the hex scew up.

edit: The locking mechinism is very simular to many infant/childrens toys.

I'll look into some other methods!

I successfully made an adjustment tool:

Great - glad U figured it out...

I think I know which thread U meant to link to, but that URL just goes back to the index - not a thread...

The URL works for me; it takes me to the correct thread.

Back to the index for me. Must be because it goes to something personally set up for U thru your login. Strange.

that is strange!

Well, here's the post I made in the other thread:

Materials required: Highlighter marker cap (Standard sized highlighter) of ~0.54" OD

Tools required: grinder

Find a cap that is about 0.54" OD. Grind off enough material so that 2 notches about 0.1" wide remain. Keep trimming until it fits the adjustment bushings on the reflex sight.

If you break one cap, find another one. A whole pack of highlighters or markers can be bought for under $2 USD. It sure beats $28 or $50, and we only really zero out the sights a few times at most since the PS90 was never intended to be a target/precision rifle.

Why plastic? It's easy to work with, it won't scratch the weapon, and the highlighters/markers are usually non-toxic so it's safe to work with. The marker caps are soft enough to grind through quickly so watch the RPMs. The marker caps are also hard enough to turn the adjustment bushings.

I love working with metal until I get steel shavings/chips embedded in my skin, or covering the garage floor.
