Tech Sights for an SKS - anyone use them?

[Calculon]

Considering putting a set of these on an SKS. Increases the sight plane by 10 inches and if you buy the TS200 you also get elevation adjustment. I'm hesitating as there is a linked video by nutnfancy that talks about them. While he loves them he also says he had to dremel away part of the rear sight base (original sight) to get a clear sight line using the TS100 (not elevation adjustable)

I'd love to put them on and be able to tighten up groups at 50 and 100 yds but I don't want to permanently alter any part of the rifle. Anyone use them?
Thanks.

I've never used them, but mines just a "for fun" plinker. I'm happy hitting thughes ' steel plate every 4th time or so. I Def wouldn't take a Dremel to one though.

I've thought about them but don't like having to remove the rear sight blade (even though it is not a permanent mod). I can hit a standard IDPA-sized steel at 200 yards with 8 out of 10 shots and shoot 2" groups at 50 yards using the stock sights....I'm good with that.
