kapp sight rail?

[Laku]

True. So maybe it's meant for classic RT like OPBN suggested.

Wonder if mine is a KAPP as well. It's black with slightly different holes on the side. They're more straight up and come to a point instead of slant back like yours. It's a shame too because I really like it, thought about just having it milled to allow a fitting in there.

i'm pretty sure these are for a spyder, and were mislabled.

or, you put it on backwards. flip it around, and see if it fits then.

I'll turn it around tonight and see if it helps any.:)

Use a hammer and a piece of 1 1/8 od heavy wall pipe. I had mine for years and they do fit spyders, so I looked at as nothing ventured nothing gained. So it was pound and check and pound, I was rather put out when the air port was covered. Now I'm just trying to figure where to put a hole and how long I'm going to spend fileing on to fit right. I'm letting mine sit before frustration turns it into scrap. It won't rattle though, it's still very tight. So break out the hammers and tongs and torture yourself.

...or just sell the things to people with spyders and then use that money to buy a proper automag sight rail...or something. lol.

Yeah I flipped it around but still covers air port on valve,so yeah prolly for spyders but does look cool.:)
