MTL SightPic Picatiny RTA Clone

[zouzounaki]

I do tend to agree with you. Relatively recently I wanted to revive my old Galaxies RDTA, which was left for 3 years or so with some small residues in.
After dismantling and cleaning, I've realised that I am unable to assemble it back as the orings have swollen that much taht I would brerak glass rather than re-fit it.
Therefore I do believe that three years is max for "normal" orings. I do know that more expensive tanks are using other than buna-n or epdm material, e.g. the one I've just ordered today: The Rook uses Viton orings, so these shall survive longer.
Yet: I really doubt if the original (not mentioning the clone) would have this in mind.

i think it may be that the design of this tank would put more strain on these o rings than normal.

golden greek had the tilemahos armed, where the idea was to use zirconium wire, which is springy, and the coil just slightly wedged between 3mm gaps in the posts. it actually worked fine with 316l wire, and no need for any kind of hinged mechanis and springs.

my thinking is you rarely need to replace screws but i think you will definitely need to replace the orings on this attie.

Time will tell but for what I paid for a clone I can't say I'm bothered.

As much I wanted to like it never got on with that tank
But never tried building that way,
Maybe it’s worth a revisit,

use 28g stainless wire and wrap it on the tool that comes with it. you’ll need quite a few wraps, but can also space it widely.

Going to require some digging to find that thing, but will give it a go
